word
sp
HELPS
sp
ME
TO
SORT
sp
OF
SEE
HOW
THE
LESSON
S
GOING
sp
RIGHT
sp
SO
sp
THAT'S
sp
MATHS
sp
IS
sp
IT
sp
HOW
DO
sp
YOU
FEEL
ABOUT
LAST
sp
WEEK'S
sp
ERM
sp
IT
WAS
GOOD
I
MADE
A
LOT
OF
sp
PROGRESS
IN
sp
IT
sp
COMPARED
TO
USUAL
sp
YEAH
sp
YEAH
sp
THAT
THAT'S
HOW
I
sp
FELT
THAT
sp
YOU
WERE
GETTING
sp
INTO
IT
sp
YOU
sp
WERE
UNDERSTANDING
sp
HOW
sp
THE
BITS
TIED
sp
TOGETHER
sp
YEAH
AND
MAKING
sp
SENSE
sp
OF
sp
IT
SO
sp
YOU'RE
sp
FEELING
HAPPIER
WITH
IT
sp
YEAH
A
sp
LOT
sp
BETTER
sp
OKAY
ERM
sp
WHAT
YOU
DONE
SINCE
sp
LAST
sp
TIME
ERM
sp
I
DID
THAT
sp
WORK
sp
YOU
ASKED
ME
TO
sp
DO
sp
GREAT
sp
GREAT
sp
AND
DID
IT
MAKE
SENSE
sp
SORT
OF
sp
YEAH
I
sp
WAS
A
BIT
OKAY
sp
IT
IT
GOT
AWAY
A
BIT
YOU
KNOW
AND
sp
AND
THIS
sp
THIS
IS
WHAT
I'M
SAYING
LAST
TIME
THAT
IF
sp
YOU'LL
sp
WORK
THROUGH
IT
sp
UNDERSTAND
IT
sp
OH
YEAH
I
sp
CAN
DO
THAT
sp
YEAH
sp
BUT
IF
YOU
IF
YOU
IF
THAT'S
ALL
YOU
DO
sp
THEN
IN
EVE
sp
EVEN
A
WEEK'S
TIME
sp
BUT
sp
DEFINITELY
IN
A
sp
FEW
MONTHS
TIME
sp
IT'S
JUST
GONE
sp
YOU'LL
JUST
HAVE
THIS
VAGUE
MEMORY
THAT
sp
OOH
I
sp
COULD
sp
DO
THAT
sp
ONCE
sp
NOW
sp
WHERE
D
sp
HOW
DO
I
GET
sp
STARTED
YEAH
HOW
DO
I
GET
INTO
sp
IT
SO
YOU
NEED
THE
PRACTICE
ERM
sp
BEEN
TENDING
sp
TO
CONCENTRATE
sp
ON
sp
SPECIFIC
THINGS
sp
WHICH
YOU
KNOW
sp
STAND
A
sp
GOOD
CHANCE
OF
sp
BEING
sp
ON
THE
sp
PAPER
AND
EVEN
IF
sp
THEY'RE
NOT
sp
WILL
sp
HELP
YOU
sp
WITH
OTHERS
sp
SO
HOW
MUCH
OF
IT
DID
YOU
UNDERSTAND
sp
ERM
sp
WHICH
BITS
sp
WERE
YOU
HAPPY
sp
WITH
sp
THE
sp
POSITIVE
sp
AND
THE
NEGATIVE
sp
OKAY
ERM
sp
SO
sp
FROM
YOUR
TABLE
sp
YOU
sp
COULD
FIND
OUT
sp
YEAH
sp
THERE'S
A
sp
GOOD
CHANCE
sp
THAT
sp
ONE
OF
THE
sp
POSITIVES
sp
WILL
GO
WITH
ONE
OF
THOSE
sp
NEGATIVE
YEAH
AND
YOU
CAN
sp
MAKE
SOMETHING
OUT
OF
IT
sp
RIGHT
sp
NOW
sp
WHAT
WHAT
WERE
THE
BITS
sp
THAT
sp
WERE
sp
A
sp
BIT
sp
TRICKY
sp
THEN
ERM
sp
JUST
REMEMBERING
SAY
I
sp
HAD
sp
TO
sp
PUT
sp
FOUR
O
HS
WITH
N
sp
H
sp
I
WAS
SOMETIMES
I
WAS
GETTING
IT
RIGHT
SOMETIMES
I
WAS
GETTING
sp
IT
WRONG
AND
sp
STUFF
LIKE
THAT
sp
RIGHT
sp
SO
FOR
THE
sp
FOR
THE
DIAGRAM
sp
IT
sp
WAS
JUST
WHERE
I
WAS
PUTTING
THE
sp
FOUR
I
sp
WASN'T
SURE
sp
ABOUT
YEAH
sp
THE
DIAGRAM
WAS
sp
OKAY
sp
WHAT
sp
WAS
PHYSICALLY
HAPPENING
sp
YOU
COULD
sp
RELATE
TO
sp
THAT
AND
sp
YOU
sp
GOT
THAT
SORTED
OUT
sp
NOW
HOW
DO
YOU
PUT
IT
DOWN
ON
sp
PAPER
sp
WHAT'S
sp
THE
sp
NOTATION
sp
THAT
YEAH
sp
THAT'S
sp
THE
ONLY
PROBLEM
sp
OKAY
YEAH
sp
SO
sp
YOU'RE
UNDERSTANDING
IT
sp
YOU
COULD
EXPLAIN
THAT
sp
TO
sp
ME
sp
YEAH
sp
YEAH
sp
YOU
sp
COULD
SAY
WHAT
IT
LOOKED
sp
LIKE
sp
AND
WHAT
sp
WAS
HAPPENING
AND
sp
THEN
SAY
sp
WELL
I'M
NOT
sp
QUITE
SURE
sp
WHAT
sp
THE
sp
CONVENTION
sp
IS
sp
FOR
WRITING
THEM
RIGHT
sp
DOWN
sp
WELL
sp
THAT'S
sp
FINE
I
sp
MEAN
THE
CONVENTION
IS
sp
EACH
OF
THESE
sp
EX
sp
I
MEAN
sp
WHAT
sp
YOU
COULD
HAVE
sp
YOU
COULD
PUT
sp
BRACKETS
ROUND
EVERYTHING
sp
IF
YOU
THINK
OF
MATHS
sp
YOU
sp
CAN
sp
YOU
CAN
PUT
BRACKETS
IN
sp
WHERE
YOU
DON'T
sp
NEED
sp
THEM
CAN'T
sp
YOU
sp
YEAH
SO
sp
YOU
COULD
sp
PUT
sp
THERE
sp
IF
sp
I
sp
WANTED
TO
sp
DO
SOMETHING
sp
LIKE
sp
THREE
ADD
sp
SIX
sp
I
sp
COULD
PUT
sp
BRACKETS
sp
ROUND
sp
THE
THREE
AND
sp
ROUND
THE
sp
SIX
sp
AND
IT
sp
WOULDN'T
sp
MAKE
ANY
sp
DIFFERENCE
ERM
IF
I
PUT
sp
TWO
sp
TIMES
sp
BRACKETS
sp
THREE
ADD
sp
SIX
sp
IT
DOES
MAKE
A
sp
DIFFERENCE
MHM
sp
YEAH
sp
MM
IT
MAKES
A
sp
BIG
DIFFERENCE
sp
WELL
IT'S
THE
SAME
sp
WITH
THIS
sp
IF
YOU
PUT
SOMETHING
LIKE
sp
N
H
sp
AND
sp
THEN
sp
O
H
FOUR
sp
WELL
sp
THE
sp
CONVENTION
IS
sp
THAT
sp
WHEN
IT'S
A
sp
SUFFIX
sp
STUFF
sp
A
sp
SUBSCRIPT
sp
AND
A
SUFFIX
sp
BELOW
THE
LINE
sp
THERE
AND
sp
JUST
AFTER
sp
IT
sp
IT
ONLY
APPLIES
sp
TO
THE
LAST
sp
ELEMENT
sp
YEAH
sp
USUALLY
sp
MEAN
sp
THE
LAST
sp
LETTER
sp
COS
MOST
OF
THE
{OOV}
sp
WELL
A
LOT
OF
THE
LE
sp
THE
ELEMENTS
sp
HAVE
sp
ONE
LETTER
sp
SO
THAT
WOULD
JUST
BE
sp
FOUR
HS
AND
sp
ONE
O
sp
RIGHT
TO
sp
MAKE
IT
MEAN
sp
THAT
sp
YOU'VE
sp
GOT
sp
FOUR
OS
AS
WELL
sp
YOU
sp
PUT
sp
IT
IN
sp
BRACKETS
sp
SO
sp
WITH
THE
sp
MATHS
sp
IT'S
sp
LIKE
sp
IT'S
sp
THE
sp
DIFFERENCE
BETWEEN
sp
FOUR
TIMES
sp
O
sp
H
OR
sp
JUST
SORT
sp
OF
O
sp
PLUS
sp
FOUR
H
sp
FOUR
O
sp
PLUS
sp
H
SO
sp
ANYTHING
THAT
YOU'VE
GOT
sp
FOUR
OF
sp
PUT
A
sp
BRACKET
sp
ROUND
sp
IT
sp
RIGHT
ERM
sp
IF
WE
HAD
SOMETHING
sp
LIKE
ERM
sp
N
H
sp
FOUR
sp
AND
sp
WE
sp
HAD
SOMETHING
sp
WITH
A
VALENCY
sp
OF
sp
EIGHT
sp
SAY
sp
WHICH
IS
sp
IMPOSSIBLE
sp
YEAH
BUT
sp
WE
HAD
sp
ONE
sp
WITH
EIGHT
SO
WE'D
HAVE
sp
WE'D
HAVE
THE
sp
WHOLE
sp
THING
sp
THERE
sp
TWICE
sp
SO
sp
HOW
MANY
HS
sp
WOULD
sp
YOU
sp
HAVE
IN
THAT
WEIRD
THING
sp
ER
EIGHT
sp
YEAH
AND
HOW
MANY
NS
sp
ONE
sp
NO
EIGHT
sp
TWO
sp
TWO
sp
SO
YEAH
ANYTHING
INSIDE
YOUR
BRACKETS
sp
MULTIPLIED
sp
BY
sp
WHAT
YOU'VE
GOT
OUTSIDE
sp
JUST
THE
sp
WAY
YOU
WOULD
sp
HAVE
sp
TWO
TIMES
sp
BRACKETS
sp
THREE
ADD
SIX
sp
CLOSE
sp
BRACKETS
sp
OKAY
sp
YEAH
sp
SO
sp
IT'S
sp
THE
SAME
sp
SAME
sp
WITH
THIS
IT'S
JUST
A
SLIGHTLY
sp
DIFFERENT
CONVENTION
sp
BUT
sp
MM
BASICALLY
IT
IS
sp
MATHS
sp
IT'S
TELLING
US
HOW
MANY
sp
SETS
OF
DIFFERENT
sp
THINGS
sp
WE'VE
sp
GOT
sp
RIGHT
sp
SO
sp
LET'S
HAVE
A
LOOK
sp
WHAT
sp
WE'VE
GOT
sp
HERE
sp
SO
sp
GOT
N
A
POSITIVE
sp
O
H
NEGATIVE
sp
N
H
sp
FOUR
POSITIVE
sp
AND
O
H
sp
NEGATIVE
sp
NOW
sp
WHAT'S
sp
GOING
ON
sp
HERE
sp
YOU'VE
sp
GOT
AN
ALKALI
sp
TRYING
TO
REACT
sp
WITH
AN
ALKALI
sp
IS
sp
THIS
sp
IS
sp
THIS
WHAT
YOU'RE
SUPPOSED
TO
sp
BE
sp
DOING
sp
WELL
THAT'S
NO
WONDER
YOU
sp
HAD
sp
TROUBLE
IS
THAT
sp
WHAT
I
sp
WROTE
ER
RIGHT
sp
WHAT
THAT'S
WHAT
I
WROTE
sp
BUT
WHAT
sp
I
SAID
sp
WAS
sp
EACH
OF
THE
ACIDS
sp
REACTING
WITH
sp
THIS
STARTING
AH
WITH
sp
HYDROCHLORIC
sp
OKAY
ONE
sp
THESE
sp
THESE
ARE
TWO
sp
THESE
ARE
TWO
sp
COMMON
sp
ALKALIS
ALKALIS
sp
OKAY
sp
THERE'S
N
A
O
sp
H
sp
WHICH
IS
sp
WHAT
sp
ER
sp
SODIUM
sp
HYDROXIDE
sp
OKAY
sp
AND
sp
N
H
sp
FOUR
O
H
sp
WHICH
sp
IS
sp
NITROGEN
sp
HYDROXIDE
sp
NO
NO
ER
sp
HAVE
A
LOOK
IN
THE
sp
TABLES
WHAT
sp
N
sp
H
sp
FOUR
IS
N
sp
H
FOUR
{OOV}
AMMONIUM
sp
AMMONIUM
sp
OKAY
sp
N
H
THREE
sp
ON
ITS
OWN
sp
AMMONIA
sp
WHEN
IT'S
sp
COMBINED
WITH
SOMETHING
ELSE
sp
IT'S
sp
N
H
sp
FOUR
ION
sp
AND
IT'S
sp
AMMONIUM
sp
LIKE
ERM
sp
CHLORINE
ON
sp
ITS
sp
OWN
CHLORINE
sp
COMBINE
IT
sp
WITH
sp
SODIUM
IT
sp
BECOMES
A
CHLORIDE
RIGHT
sp
SO
sp
LET'S
HAVE
A
LOOK
AT
THAT
NOW
sp
YOU
sp
SHOULDN'T
HAVE
ANY
PROBLEM
sp
WITH
sp
SO
sp
YOU'VE
sp
TRIED
sp
THERE
sp
WITH
sp
WHICH
ACID
DO
YOU
WANT
TO
USE
sp
HYDROCHLORIC
S
sp
PROBABLY
THE
sp
SIMPLEST
sp
SO
HAVE
A
sp
GO
WITH
sp
THAT
FIRST
sp
BECAUSE
THEN
YOU
CAN
SEE
THE
sp
PATTERN
sp
ER
sp
HYDROCHLORIC
sp
ACID
sp
IS
sp
ERM
ERM
sp
NO
ERM
sp
IT'S
GOT
sp
ERM
HYDROCHLORIC
sp
WHAT
sp
DOES
sp
THAT
sp
SOUND
LIKE
sp
HYDROGEN
AND
sp
CHLORINE
sp
OKAY
H
C
L
THAT
WAS
IT
YEAH
RIGHT
I
sp
COULDN'T
REMEMBER
OKAY
sp
GREAT
sp
SO
sp
IT'S
sp
H
sp
C
L
sp
AND
C
L'S
GOT
sp
A
VALENCY
OF
sp
ONE
sp
SO
THAT'S
sp
NICELY
sp
BALANCED
sp
ONE
C
L
sp
WITH
sp
ONE
sp
H
sp
PLUS
ERM
sp
NOW
sp
YOU'VE
DONE
THAT
sp
QUITE
A
sp
FEW
TIMES
sp
BEFORE
sp
N
A
O
sp
SO
sp
DO
THE
N
A
O
sp
H
FIRST
AND
sp
YOU
sp
SHOULD
sp
BE
ABLE
sp
TO
sp
WHIZ
THROUGH
sp
THAT
sp
YES
sp
ERM
sp
SO
THEN
sp
YOU
CAN
sp
WORK
sp
OUT
sp
WHICH
ARE
sp
POSITIVE
sp
AND
WHICH
ARE
RIGHT
sp
HYDROGEN
S
THE
sp
ONE
WE
sp
TEND
TO
sp
TREAT
AS
A
A
sp
METAL
sp
YEAH
sp
HYDROGEN
sp
IS
POSITIVE
sp
RIGHT
CHLORINE
sp
IS
A
NEGATIVE
sp
ER
sp
SODIUM
sp
IS
sp
A
POSITIVE
sp
HYDROXIDE
sp
IS
sp
YOU'VE
sp
GOT
sp
ONE
sp
HERE
THERE
sp
ARE
sp
SOME
sp
ON
THIS
sp
YEAH
ER
sp
NEGATIVE
RIGHT
YEAH
sp
SO
SO
MOST
OF
THESE
ARE
ONE
POSITIVE
sp
AND
ONE
sp
NEGATIVE
SO
sp
THE
HYDROGEN
sp
WITH
GO
sp
WITH
sp
HYDROXIDE
sp
OKAY
sp
MAKING
ERM
sp
SO
sp
THAT'S
sp
H
sp
TWO
sp
O
sp
PLUS
sp
THIS
TWO
H
DOW
sp
THERE
YEAH
sp
WHERE
DOES
THE
sp
TWO
GO
sp
DOWN
THERE
sp
RIGHT
sp
OKAY
sp
TWO
GOES
sp
DOWN
sp
THERE
SO
sp
IT'S
TWO
WHAT
sp
TWO
WHATEVER
LETTER
CAME
sp
BEFORE
sp
IT
YEAH
sp
TWO
HS
sp
AND
sp
ONE
sp
O
sp
AND
ON
sp
THE
C
L
sp
WE
sp
ADD
sp
THE
sp
SO
YEAH
sp
WE
sp
GET
sp
SODIUM
C
L
sp
IS
A
sp
NEGATIVE
N
A
IS
sp
IS
A
sp
POSITIVE
sp
HOW
MANY
sp
THAT'S
SPARE
sp
ONE
sp
SPARE
OKAY
sp
TRANSFER
sp
THAT'S
N
A
sp
C
L
YEAH
sp
THAT'S
sp
IT
sp
THAT'S
H
sp
TWO
O
AND
sp
S
O
YOU
WRITE
THE
EQUATION
OUT
FOR
sp
THAT
sp
NOW
sp
THAT'S
N
A
sp
C
sp
L
sp
ERM
sp
THE
sp
SORT
OF
sp
ERM
FROM
WHAT
YOU
START
WITH
FROM
sp
WHAT
IT
sp
GIVES
sp
FROM
sp
THE
HYDROCHLORIC
ACID
AND
sp
THE
OH
sp
RIGHT
sp
H
C
sp
L
sp
PLUS
N
sp
A
O
H
sp
IS
EQUAL
sp
TO
N
sp
A
C
L
sp
RIGHT
sp
YEAH
sp
PLUS
sp
H
sp
TWO
O
sp
RIGHT
sp
GREAT
sp
SO
WHAT'S
THE
sp
SORT
OF
sp
GENERAL
sp
TERM
sp
FOR
THIS
sp
THIS
sp
IS
AN
sp
HYDROGEN
sp
CHLORIDE
sp
YEAH
ER
sp
WHAT
ABOUT
THIS
sp
THEN
sp
SODIUM
HYDROXIDE
AND
sp
IT'S
AN
EXAMPLE
OF
sp
WHAT
sp
AN
ALKALI
sp
OKAY
sp
THIS
sp
IS
sp
ER
ACID
sp
SO
YOU
sp
CAN
sp
JUST
WRITE
UNDER
sp
IT
ACID
sp
PLUS
sp
ACID
sp
PLUS
sp
GIVES
sp
EQUALS
sp
N
sp
A
C
L
sp
IS
A
sp
ALKALI
sp
ERM
NO
IT'S
sp
NOT
IT'S
A
sp
SALT
sp
GOOD
sp
IT'S
A
sp
SALT
sp
AND
YOU
KNOW
WHAT
sp
AND
sp
WATER
RIGHT
sp
AND
THAT'S
A
sp
GENERAL
sp
REACTION
THAT
sp
HAPPENS
sp
WITH
VIRTUALLY
sp
ANY
sp
ACID
AND
ANY
ALKALI
ACID
sp
AND
ANY
ALKALI
SALT
AND
sp
WATER
sp
ER
SO
sp
HAVE
ANOTHER
GO
sp
NOW
sp
AT
A
SIMILAR
SORT
OF
REACTION
sp
SAME
ACID
sp
THIS
TIME
USE
A
DIFFERENT
ALKALI
sp
USE
sp
AMMONIUM
sp
HYDROXIDE
sp
WHICH
sp
IS
sp
AMMONIUM
N
H
sp
FOUR
sp
USUALLY
sp
PUT
sp
THE
sp
ACID
FIRST
sp
RIGHT
sp
THE
ACID
sp
AND
sp
WHAT
ACID
sp
GON
NA
sp
USE
SO
sp
USE
THE
SAME
sp
ONE
sp
SO
H
sp
C
sp
L
sp
PLUS
sp
AMMONIUM
sp
HYDROXIDE
THAT'S
N
sp
H
NOW
sp
IT'S
GOT
sp
FOUR
sp
SPARE
sp
ONES
sp
AND
sp
THE
sp
HYDROXIDE
sp
HAS
sp
GOT
ER
WHOA
WHOA
WHOA
sp
NOW
sp
IT'S
N
H
sp
FOUR
sp
RIGHT
sp
YEAH
SO
PUT
sp
THE
sp
PUT
sp
THE
sp
FOUR
ON
FOR
N
sp
H
sp
FOUR
NOW
IF
YOU
LOOK
sp
IT
UP
ON
THE
TABLE
sp
LET'S
HAVE
A
LOOK
sp
AT
ERM
sp
SAY
sp
CALCIUM
sp
DOUBLE
POSITIVE
sp
RIGHT
sp
ZINC
sp
DOUBLE
sp
POSITIVE
sp
THIS
sp
THIS
sp
TYPE
sp
OF
sp
ION
TRIPLE
POSITIVE
IS
sp
A
sp
TRIPLE
sp
POSITIVE
sp
BUT
sp
N
H
sp
FOUR
sp
SO
IT'S
A
sp
SINGLE
POSITIVE
sp
OH
RIGHT
sp
OKAY
sp
YEAH
SO
IT'S
FOUR
HYDROGEN
WITH
sp
THE
sp
FOUR
HYDROGEN
sp
ONE
NITROGEN
sp
ALL
THEIR
BONDS
GOT
sp
GET
TOGETHER
sp
AND
THERE'S
sp
ONE
sp
THE
RESULT
IS
sp
ONE
sp
POSITIVE
sp
BOND
sp
LEFT
OVER
sp
RIGHT
sp
OKAY
YOU'RE
NOT
TOO
BOTHERED
ABOUT
WHAT'S
GOING
sp
ON
sp
INTERNALLY
SO
sp
IT'S
N
H
sp
FOUR
sp
O
sp
H
sp
SO
sp
N
H
sp
FOUR
O
sp
H
sp
BECAUSE
sp
IT'S
sp
IT'S
JUST
sp
ONE
sp
POSITIVE
sp
ON
sp
THAT
sp
WHOLE
sp
N
H
sp
FOUR
sp
CLUSTER
sp
AND
sp
WE
sp
WE
sp
THINK
OF
THAT
AS
AN
ENTITY
sp
THAT'S
A
sp
POSITIVE
sp
THAT'S
sp
A
sp
NEGATIVE
ER
sp
THAT'S
A
sp
POSITIVE
sp
THAT'S
A
sp
NEGATIVE
sp
MHM
sp
SO
THE
sp
POSITIVE
sp
THE
NEGATIVE
sp
YEAH
sp
THAT'S
GOOD
AND
THE
sp
NEGATIVE
sp
THE
sp
POSITIVE
THAT'S
IT
THA
I
sp
LIKE
sp
THE
WAY
YOU
DID
IT
sp
BECAUSE
THAT'S
A
sp
GOOD
ONE
TO
DO
FIRST
sp
THE
H
POSITIVE
sp
AND
THE
O
H
NEGATIVE
ARE
GOING
sp
TO
GIVE
YOU
THE
sp
WATER
sp
NOW
sp
WHAT
ARE
YOU
LEFT
OVER
sp
WITH
sp
IT'S
sp
A
NICE
NICE
sp
THAT
FOR
WORKING
sp
IT
sp
THROUGH
sp
SO
THAT
PUT
sp
THE
EQUALS
UNDERNEATH
sp
SO
sp
H
sp
SO
THE
sp
CHLORINE
sp
AND
sp
THE
N
sp
H
sp
FOUR
sp
CHLORINE
HAS
GOT
sp
ONE
sp
SPARE
sp
ONE
RIGHT
AND

ALKALI
OKAY
NOW
sp
TRY
DO
YOU
REMEMBER
THE
FORMULA
FOR
sp
SULPHURIC
ACID
sp
SULPHURIC
sp
ACID
sp
ERM
sp
YEAH
sp
I
sp
WILL
DO
NOW
OKAY
OR
NITRIC
IF
sp
THAT'S
EASIER
sp
WHICHEVER
ONE
YEAH
sp
COMES
sp
FIRST
sp
ERM
N
A
O
sp
H
sp
NO
sp
THAT'S
SODIUM
HYDROXIDE
THE
ONES
ENDING
IN
O
H
YEAH
sp
ARE
THE
ALKALIS
sp
YEAH
sp
OKAY
sp
THE
ACIDS
sp
ALL
sp
START
WITH
I
KNOW
IT
IT'S
sp
JUST
THAT
WITH
AN
H
sp
YEAH
sp
WELL
YOU
KNOW
sp
WE
PUT
sp
THE
H
sp
FIRST
sp
H
sp
TWO
sp
S
O
FOUR
sp
BRILLIANT
sp
OKAY
sp
YEAH
SO
H
TWO
S
sp
O
sp
FOUR
RIGHT
sp
BEFORE
WE
GO
ANY
FURTHER
WITH
sp
THAT
sp
H
TWO
S
O
sp
FOUR
sp
HOW
MANY
HS
IN
IT
sp
TWO
AND
sp
HOW
MANY
SS
sp
ONE
sp
GOOD
sp
ONE
sp
S
sp
IF
WE'D
PUT
sp
BRACKETS
ROUND
FOUR
OS
THE
WHOLE
LOT
AND
THEN
A
FOUR
sp
DOWN
sp
THERE
IT
WOULD
HAVE
sp
BEEN
sp
FOUR
sp
BUT
sp
FOUR
OS
ONLY
sp
ONE
sp
S
sp
RIGHT
sp
OKAY
sp
PLUS
ERM
sp
PLUS
sp
YOU
COULD
DO
sp
AMMONIUM
sp
ERM
sp
NOW
LET'S
HAVE
A
sp
CALCIUM
sp
ERM
sp
HYDROXIDE
sp
CALCIUM
sp
THAT'S
C
A
sp
TWO
sp
PLUS
sp
C
sp
A
AND
sp
THAT'S
A
DOUBLE
sp
POSITIVE
sp
RIGHT
sp
SO
sp
SO
I'M
GON
NA
NEED
sp
TWO
sp
HYDROXIDE
sp
TWO
HYDROXIDES
COS
sp
THEY'RE
JUST
sp
A
sp
SINGLE
NEGATIVE
sp
WHICH
IS
sp
O
sp
H
O
sp
H
sp
NOW
HOW
sp
MANY
OF
THOSE
DO
sp
YOU
WANT
sp
IN
BRACKETS
sp
GREAT
AND
THERE
ARE
TWO
sp
RIGHT
RIGHT
sp
YOU
GOT
sp
THE
THE
O
H
IS
THE
sp
BIT
sp
YOU
WANT
TWICE
sp
SO
sp
WRITE
IT
sp
DOWN
sp
PUT
THE
sp
BRACKETS
ROUND
sp
IT
sp
AND
THEN
sp
THE
sp
TWO
sp
RIGHT
HYDROGEN
sp
IS
sp
POSITIVE
sp
RIGHT
sp
SO
sp
THAT'S
sp
POSITIVE
sp
THE
sp
SULPHUR
sp
SULPHOXIDE
sp
SULPHATE
sp
SULPHATE
sp
IS
A
DOUBLE
sp
NEGATIVE
sp
YEAH
SULPHOXIDE
sp
WAS
A
sp
GOOD
SORT
OF
sp
AND
sp
THEN
I'M
sp
I'M
A
BIT
sp
ANY
OF
THE
ATES
sp
ANY
OF
THE
ATES
HAVE
sp
GOT
sp
OXYGEN
IN
YEAH
sp
IN
sp
AS
sp
WELL
sp
SO
sp
NITRATE
sp
HAS
GOT
sp
NITROGEN
sp
AND
OXYGEN
IN
IT
THE
CALCIUM
sp
IS
A
DOUBLE
sp
POSITIVE
sp
AND
THE
sp
O
H
sp
IS
sp
A
sp
THAT'LL
BE
A
DOUBLE
sp
NEGATIVE
COS
sp
THERE'S
TWO
OF
THEM
NO
sp
WELL
NOW
sp
NO
NO
NO
NO
COS
sp
THEY'RE
sp
JOINED
TOGETHER
THAT'LL
BE
A
SINGLE
NEGATIVE
O
H
sp
O
H
IS
IS
A
SINGLE
NEGATIVE
BUT
sp
KEEP
IT
INSIDE
sp
THE
sp
BRACKET
THAT'S
IT
sp
AND
sp
DON'T
sp
FORGET
sp
THE
TWO
APPLIES
TO
EVERYTHING
sp
INSIDE
sp
THERE
SO
YEAH
WE'LL
sp
FINISH
sp
UP
WITH
sp
TWO
NEGATIVES
sp
ONE
FROM
EACH
sp
O
H
sp
SO
sp
HYDROGEN
sp
RIGHT
sp
REACTS
sp
WITH
sp
THE
O
sp
H
sp
YEAH
sp
AND
sp
THE
sp
S
O
FOUR
sp
REACTS
sp
WITH
C
A
sp
THE
sp
CALCIUM
sp
SO
sp
HYDROGEN
sp
THERE'S
sp
TWO
OF
sp
THIS
HYDROXIDE
sp
TWO
sp
HYDROXIDES
SO
IF
YOU
JUST
sp
WRITE
sp
TWICE
JUST
sp
WRITE
sp
O
H
sp
NEGATIVE
sp
AND
sp
THEN
ANOTHER
O
H
NEGATIVE
sp
YEAH
sp
H
sp
TWO
sp
ER
NO
sp
YEAH
I
NEED
sp
H
sp
TWO
sp
O
H
sp
MM
sp
NO
sp
TWO
H
TWO
O
sp
BRILLIANT
sp
TWO
H
TWO
O
sp
YEAH
sp
WHAT
WE'VE
GOT
IF
sp
YOU
WRITE
THEM
OUT
SEPARATELY
sp
YEAH
sp
JUST
TO
SHOW
WHAT'S
HAPPENING
sp
WHAT
HAVE
WE
GOT
sp
WE'VE
GOT
TWO
LOTS
OF
sp
H
POSITIVE
OKAY
sp
THERE'S
ONE
H
sp
POSITIVE
sp
AND
sp
THERE'S
sp
ANOTHER
H
sp
POSITIVE
sp
YEAH
sp
THEY'RE
sp
TWO
SEPARATE
sp
IT'S
sp
H
sp
POSITIVE
sp
TIMES
sp
TWO
sp
WHAT
HAVE
WE
GOT
HERE
sp
O
H
sp
NEGATIVE
sp
TIMES
sp
TWO
sp
TWO
LOTS
OF
sp
O
H
NEGATIVE
sp
RIGHT
sp
NOW
WE'RE
sp
JUST
sp
BACK
sp
ONTO
sp
WHAT
sp
WE
WERE
DOING
sp
HERE
sp
ONE
H
sp
POSITIVE
sp
ONE
O
sp
H
NEGATIVE
sp
GIVES
sp
YOU
sp
THE
H
TWO
O
WE'VE
sp
GOT
sp
TWO
LOTS
sp
OF
sp
THAT
sp
SO
WE'RE
GOING
TO
GET
TWO
H
TWO
O
sp
MHM
AND
YOU'VE
EVEN
sp
AND
sp
YOU'VE
EVEN
BALANCED
THE
sp
EQUATION
sp
AS
sp
YOU'VE
sp
DONE
sp
IT
AND
sp
THEN
WHAT'S
sp
LEFT
sp
OVER
sp
RIGHT
sp
TWO
sp
H
sp
TWO
sp
O
AND
NOW
sp
WE'VE
sp
GOT
sp
THE
sp
SULPHATE
sp
AND
sp
THE
sp
CALCIUM
sp
MHM
sp
AND
THEY'RE
sp
BOTH
DOUBLE
sp
NEGATIVE
sp
AND
DOUBLE
POSITIVE
sp
THAT'S
RIGHT
sp
SO
sp
IT'S
C
A
sp
S
sp
O
sp
FOUR
SO
THAT'S
sp
THAT'S
sp
SOMETHING
THAT
sp
YOU'VE
sp
NEVER
sp
DONE
sp
BEFORE
sp
AN
EQUATION
sp
YOU'VE
sp
ST
sp
PERHAPS
NEVER
EVEN
HEARD
sp
OF
CALCIUM
sp
SULPHATE
sp
BUT
JUST
FROM
THAT
LITTLE
sp
TABLE
sp
WHICH
YOU'LL
GET
sp
USED
TO
sp
AS
sp
WORK
sp
THROUGH
sp
THEM
sp
YOU
CAN
WORK
sp
WHAT
WOULD
sp
HAPPEN
sp
SO
YOU
CAN
MM
WORK
OUT
sp
WHAT
sp
WOULD
sp
HAPPEN
FOR
ANY
OF
sp
THE
sp
ANY
OF
THE
sp
ACIDS
WITH
ANY
OF
THE
ALKALIS
MM
ERM
DO
sp
YOU
sp
WANT
sp
TO
TRY
ANOTHER
sp
ONE
sp
YEAH
sp
YEAH
sp
YEAH
IT'S
sp
THE
sp
THE
THE
TIME
TO
sp
DO
ANOTHER
sp
ONE
sp
IS
WHEN
YOU
THINK
OH
YEAH
THERE'S
sp
NO
sp
PROBLEM
sp
HERE
sp
I'VE
sp
DEFINITELY
GOT
sp
THIS
sp
THEN
IT'S
A
sp
GOOD
IDEA
sp
JUST
TO
DO
ANOTHER
sp
ONE
AND
sp
MAKE
SURE
sp
OKAY
SH
SO
ERM
sp
LET'S
TRY
sp
MM
sp
SAY
STAY
WITH
ERM
SULPHURIC
ACID
sp
SO
sp
SULPHURIC

sp
PLUS
ERM
SULPHURIC
ER
YEAH
SULPHURIC
sp
ACID
PLUS
sp
WHAT
sp
SHALL
sp
WE
HAVE
sp
OUT
sp
OF
sp
THIS
sp
LOT
ERM
HOW
ABOUT
sp
AMMONIUM
sp
ERM
sp
HYDROXIDE
sp
H
sp
H
sp
TWO

WHAT
WAS

AGAIN
ERM
AMMONIUM

FOUR
ER
sp
O
sp
H
sp
RIGHT
sp
I
KNOW
sp
THAT'S
A
sp
POSITIVE
sp
THAT'S
A
sp
DOUBLE
sp
NEGATIVE
sp
THE
N

H
FOUR
sp
A
sp
POSITIVE
sp
AND
sp
THAT
sp
IS
A

sp
SO
AGAIN
sp
THE
sp
H
TWO
sp
AND
THE
O
sp
H
sp
RIGHT
sp
MAKE
ER
sp
H
sp
TWO
sp
O
sp
OKAY
sp
H
sp
O
sp
PLUS
WHAT
HAVE
YOU
sp
GOT
LEFT
OVER
sp
THE
sp
S
sp
O
FOUR
sp
AND
sp
THE
N
sp
H
sp
FOUR
sp
THAT'S
sp
A
DOUBLE
NEGATIVE
AND
sp
THAT'S
A
SINGLE

POSITIVE
sp
IT'S
GOING
sp
TO
BE
sp
TWO
sp
N
H
sp
FOUR
sp
S
O
sp
FOUR
sp
NO
ERM
sp
LET
ME
sp
THINK
sp
ABOUT
IT
sp
AGAIN
sp
ER
sp
WHAT'S
sp
WRONG
sp
WITH
S
O
sp
FOUR
N
H
sp
TWO
N
sp
H
sp
FOUR
sp
IT'S
sp
YOU
YOU
WERE
YEAH
sp
YOU
WERE
RIGHT
sp
THE
FIRST
TIME
sp
RIGHT
sp
SO
sp
IT'S
sp
N
H
sp
FOUR
sp
TWO
N
sp
H
sp
FOUR
sp
I
sp
SAID
sp
YOU'RE
GOING
TO
HAVE
TWO
LOTS
OF
N
H
sp
FOUR
RIGHT
sp
LET'S
sp
LET'S
sp
SAY
sp
WE
WERE
DOING
sp
RIGHT
sp
NOW
sp
WHAT
DO
YOU
MEAN
BY
sp
THAT
sp
WHAT
DOES
sp
THIS
sp
TWO
APPLY
sp
TO
sp
ERM
sp
THE
N
H
FOUR
sp
SO
sp
BRACKETS
LET'S
sp
WITH
THE
TWO
AFTERWARDS
sp
RIGHT
sp
BRILLIANT
sp
SO
S
sp
O
FOUR
sp
BRACKET
sp
N
H
FOUR
TWO
RIGHT
SO
IT'S
sp
THE
sp
RIGHT
WAY
ROUND
sp
N
H
sp
FOUR
N
H
sp
FOUR
sp
TWICE
sp
SO
sp
N
H
sp
FOUR
sp
TWO
sp
S
O
sp
FOUR
S
sp
O
sp
FOUR
RIGHT
ERM
sp
WHEN
YOU
PUT
sp
TWO
H
TWO
O
WHAT
sp
DID
YOU
MEAN
TWO
sp
H
sp
TWO
O
WHEREVER
sp
IT
sp
WAS
sp
THERE
IT
sp
IS
TWO
WATERS
sp
YEAH
sp
AND
HOW
MANY
HYDROGENS
sp
ALL
TOGETHER
sp
ER
sp
ONE
OH
NO
sp
TWO
sp
FOUR
HYDROGENS
AND
sp
HOW
MANY
OXYGENS
sp
TWO
sp
RIGHT
sp
SO
IF
YOU
PUT
THE
NUMBER
IN
sp
FRONT
IT'S
sp
AS
sp
THOUGH
YOU'VE
GOT
sp
BRACKETS
sp
AROUND
THE
sp
WHOLE
sp
LOT
sp
I
MEAN
MM
REALLY
YOU
SHOULD
HAVE
sp
BRACKETS
ROUND
THE
sp
WHOLE
LOT
BUT
sp
WE
DON'T
sp
BOTHER
sp
TO
sp
PUT
sp
THEM
sp
YEAH
SHOULD
sp
DO
sp
IT'S
A
sp
BIT
SLOPPY
IN
sp
THE
NOTATION
sp
CONVENTION
sp
SO
sp
IF
sp
YOU
JUST
WANTED
sp
TWO
HYDROGENS
sp
WHEN
YOU
sp
PUT
IT
sp
DOWN
sp
HERE
IF
YOU
JUST
WANTED
sp
TWO
sp
N
H
sp
FOURS
YOU'D
sp
PUT
sp
IT
DOWN
sp
HERE
OKAY
sp
YEAH
sp
SO
sp
I
sp
THINK
sp
YOU'VE
sp
DEFINITELY
GOT
THAT
RIGHT
sp
VERY
sp
WELL
ON
THAT
sp
ERM
sp
NITRATES
sp
SULPHATES
sp
AND
WHAT
ELSE
sp
ANY
OTHER
ATES
THAT
YOU'VE
HEARD
OF
ERM
NITRATES
sp
SULPHATES
OKAY
sp
NOW
sp
JUST
sp
STICK
sp
WITH
sp
THOSE
sp
I'M
JUST
THINK
sp
I
sp
I'M
JUST
THINKING
DON'T
WORRY
ER
sp
THERE'S
sp
THERE'S
ONE
IN
THERE
sp
YEAH
I'M
JUST
THINKING
sp
ANOTHER
ATE
AND
sp
IT'S
NOT
sp
IT'S
sp
NOT
sp
THE
SAME
AS
sp
THESE
sp
AS
sp
THESE
IT'S
NOT
sp
CHLORATE
sp
CHLORATE
sp
YES
sp
THERE
IS
A
sp
CHLORATE
sp
ERM
sp
THERE'S
sp
ONE
sp
DOWN
sp
THERE
sp
CARBONATE
sp
CARBONATE
sp
WHICH
IS
sp
NOT
sp
QUITE
sp
THE
SALT
sp
NOT

THE
SORT

OF
sp
THING
YOU
GET
sp
FROM
sp
AN
sp
ACID
sp
NORMALLY
LIKE
sp
SULPHURIC
sp
SULPHURIC
ACID
sp
GIVE
sp
YOU
THE
sp
SULPHATE
sp
WHAT'S
THE
SPECIAL
sp
THING
sp
ABOUT
sp
CARBONATES
sp
AND
sp
ACIDS
sp
I
MEAN
IS
A
CARBONATE
sp
ERM
AN
ALKALI
sp
ERM
NO
sp
WHAT
sp
HAPPENS
sp
WHEN
sp
YOU
sp
DRIP

ACID
ON
A

CARBONATE
sp
DON'T

DO
YOU
KNOW
ANY
CARBONATES
ARE
sp
YOU
sp
WARMING
UP
sp
I'LL
JUST
sp
I'LL
JUST

SO
sp
WHAT
HAPPENS
WHEN
YOU
sp
DRIP

ACID
ONTO
sp
A
sp
CARBONATE
sp
DO
YOU
KNOW
ANY
sp
CARBONATES
sp
NOT
sp
REALLY
sp
NO
WELL
I
PROBABLY
DO
BUT
OKAY
ER
HAVE
sp
YOU
sp
COME
sp
ACROSS
CALCIUM
sp
CARBONATE
sp
YEAH
sp
WHAT'S
sp
THAT
sp
LOOK
sp
LIKE
ERM
IS
IT
NORMALLY
A
SOLID
sp
OR
A
LIQUID
OR
sp
WHAT
sp
A
sp
LIQUID
sp
NO
NO
sp
ERM
sp
IT'S
A

ERM
ERM

OKAY
SO
WHAT
sp
HAPPENS
sp
WHEN
YOU
DRIP
ACID
sp
ONTO
MARBLE
CHIPPINGS
sp
ER
sp
YOU
TOLD
ME
sp
LAST

WEEK
sp
REMEMBER
sp
BUT
I
sp
CAN'T
REMEMBER
sp
ER
HAVE
YOU
EVER
SEEN
IT
sp
DONE
sp
NO
ER
sp
I
MAY
HAVE
BEEN
ABSENT
OR
SOMETHING
sp
RIGHT
OKAY
WHAT
sp
OFTEN
HAPPENS
WHEN
YOU
DRIP
ACIDS
sp
ONTO
sp
THINGS
sp
THEY
sp
REACT
sp

sp
MAYBE
sp
IT'S
sp
CARBONATES
sp
THEY
sp
EFFERVESCE
sp
YEAH
sp
EFFERVESCE
sp
THEY
sp
FIZZ
A
BIT
sp
WHAT'S
sp
HAPPENING
sp
ER
THEY'RE
PRODUCING
sp
GAS
THEY'RE
GIVING
OFF
OKAY
sp
WHAT
sp
GAS
sp
CARBON
sp
DIOXIDE
sp
RIGHT
MM
sp
SO
ACID
sp
PLUS
sp
CARBONATE
sp
GIVES
sp
ER
CARBON
sp
DIOXIDE
sp
RIGHT
AND
sp
PROBABLY
sp
A
FEW
OTHER
sp
THINGS
sp
YEAH
sp
LET'S
SEE
IF
WE
CAN
sp
WORK
sp
OUT
sp
WHAT
sp
IT
IS
sp
SO
sp
LET'S
PICK
A
NICE
SIMPLE
ACID
THE
sp
CHOICE
sp
IS
sp
YOURS
ERM
sp
WHICH
IS
sp
THE
EASIEST
ONE
sp
TO
PLAY
WITH
H
C
L
sp
YEAH
sp
H
C
L
sp
GOOD
CHOICE
sp
PLUS
sp
AND
WE'LL
PICK
AN
EASY
CARBONATE
ER
sp
WE'LL
PICK
THE
sp
ONE
THAT
sp
WE
sp
NORMALLY
sp
USE
sp
CALCIUM
sp
CARBONATE
sp
WHICH
sp
IS
C
sp
A
sp
ERM
AND
sp
CARBONATE
sp
IS
C
sp
O
sp
THREE
C
sp
A
sp
C
sp
O
sp
NOW
sp
THAT'S
A
sp
POSITIVE
sp
NEGATIVE
sp
THE
sp
CALCIUM
sp
IS
A
sp
DOUBLE
sp
POSITIVE
sp
DOUBLE
{OOV}
sp
POSITIVE
sp
YEAH
sp
AND
THE
C
sp
O
sp
THREE
sp
IS
A
DOUBLE
sp
NEGATIVE
RIGHT
RIGHT
HYDROGEN
AND
sp
THE
CARBONATE
sp
SO
sp
THERE'S
GOING
TO
BE
sp
H
sp
BRACKETS
TWO
sp
C
O
sp
THREE
sp
YEAH
OKAY
sp
WELL
sp
MAYBE
sp
MAYBE
sp
IT'S
A
sp
GOOD
sp
TRY
ERM
sp
THE
sp
CHLORINE
AND
sp
THE
CALCIUM
sp
IT'S
sp
A
sp
DOUBLE
sp
POSITIVE
sp
ER
sp
AH
sp
YOU
REMEMBERING
ANYTHING
sp
GO
ON
sp
CARRY
ON
I
COULD
WRITE
TWO
H
sp
C
sp
O
THREE
ERM
WELL
WHAT'S
THE
DIFFERENCE
BETWEEN
sp
H
sp
TWO
sp
C
O
sp
THREE
sp
AND
ER
TWO
H
sp
C
O
sp
THREE
sp
THAT'S
TWO
OF
sp
H
sp
C
O
THREE
RIGHT
sp
RIGHT
sp
H
sp
TWO
sp
IS
JUST
sp
TWO
OF
sp
H
sp
RIGHT
sp
SO
THERE
I
sp
THEY'RE
NOT
THE
SAME
sp
COMPOUND
sp
AT
sp
ALL
sp
YOU
CAN'T
sp
JUST
NO
NO
SWAP
ONE
sp
FOR
THE
OTHER
sp
SO
WHAT'S
sp
WHAT'S
HAPPENING
WITH
THE
sp
CHLORINE
sp
THEN
sp
ER
TWO
sp
C
sp
A
sp
YEAH
sp
OKAY
NOW
sp
WE
USUALLY
WRITE
sp
THE
METAL
sp
FIRST
sp
YEAH
sp
SO
WE'D
HAVE
sp
CALCIUM
sp
CHLORIDE
sp
YEAH
sp
SO
I'LL
REARRANGE
IT
OKAY
HOW
sp
WOULD
sp
YOU
WRITE
sp
THAT
sp
JUST
REARRANGE
sp
THAT
sp
RIGHT
sp
OKAY
sp
WELL
THAT'S
sp
QUITE
sp
POSSIBLY
WHAT
sp
DOES
HAPPEN
sp
NOW
sp
GO
TO
sp
THE
C
L
sp
IT'S
JUST
sp
ONE
ELEMENT
sp
WE
DON'T
sp
NEED
sp
THE
BRACKETS
sp
IT
sp
WOULDN'T
BE
WRONG
sp
TO
WRITE
sp
THE
BRACKETS
sp
ROUND
IT
sp
BUT
WE
DON'T
sp
USUALLY
sp
BOTHER
NO
sp
YOU
CAN
JUST
WRITE
sp
C
A
C
sp
L
TWO
RIGHT
sp
FOR
THAT
sp
NOW
THIS
sp
THING
H
TWO
C
O
sp
THREE
ERM
sp
SO
sp
YOU'VE
TRIED
THE
REACTION
sp
YOU'VE
TRIED
THESE
sp
DIFFERENT
sp
COMPOUNDS
sp
MM
sp
PULL
EM
APART
SHOVE
EM
sp
BACK
TOGETHER
sp
AGAIN
SEE
WHAT
sp
YOU
CAN
sp
MAKE
sp
AND
YOU'VE
MADE
THIS
sp
THING
sp
HYDROGEN
sp
CARBONATE
sp
YEAH
sp
AND
sp
CALCIUM
sp
CHLORIDE
sp
THE
sp
CALCIUM
CHLORIDE
S
sp
DEFINITELY
GOING
sp
TO
GET
sp
FORMED
sp
BUT
sp
WE
DECIDED
sp
THAT
YOU
GET
sp
CARBON
DIOXIDE
sp
OH
sp
YEAH
sp
RIGHT
sp
SO
sp
MAYBE
THIS
IS
AN
INTERMEDIATE
sp
STAGE
WE
DON'T
sp
KNOW
sp
BUT
WE
KNOW
sp
CARBON
DIOXIDE
sp
COMES
OUT
OF
IT
sp
WHAT
WOULD
sp
HAPPEN
sp
IF
sp
YOU
TOOK
sp
CARBON
sp
DIOXIDE
OUT
OF
THIS
sp
WHAT
DO
sp
MHM
YOU
KNOW
THE
sp
FORMULA
sp
FOR
sp
CARBON
sp
DIOXIDE
ER
sp
DI
sp
IS
TWO
sp
ISN'T
sp
IT
sp
RIGHT
GOOD
sp
SO
sp
IT'S
sp
CARBON
sp
WHICH
IS
C
sp
RIGHT
sp
C
O
sp
TWO
sp
OKAY
sp
SO
JUST
RE
sp
WRITE
C
O
sp
TWO
sp
UNDERNEATH
sp
IT
sp
C
sp
O
TWO
NOW
IF
YOU
TOOK
sp
C
sp
O
sp
TWO
sp
OUT
OF
THAT
sp
WHAT
sp
WOULD
sp
YOU
sp
HAVE
sp
LEFT
sp
YOU'RE
sp
LEFT
sp
WITH
H
TWO
sp
O
ER
sp
SO
IT'S
sp
RIGHT
sp
H
sp
TWO
O
sp
PLUS
C
sp
O
THREE
sp
PLUS
C
O
TWO
sp
RIGHT
sp
YEAH
sp
YEAH
sp
PLUS
C
A
C
sp
L
sp
TWO
NO
sp
YOU
DON'T
NEED
THE
BRACKETS
sp
YEAH
sp
IT'S
sp
BETTER
sp
WITHOUT
sp
THE
sp
BRACKETS
sp
THEY'D
sp
PROBABLY
ACCEPT
IT
sp
WITH
OKAY
sp
SO
sp
THIS
WAS
WORKED
sp
OUT
sp
NOT
sp
REALLY
sp
KNOWING
ANYTHING
ABOUT
WHAT'S
GOING
sp
ON
sp
HERE
sp
WE'VE
GOT
sp
THAT
sp
AND
THAT
sp
GO
TOGETHER
WHAT
WOULD
HAPPEN
sp
WELL
sp
PRETTY
GOOD
sp
BET
THAT
sp
YOU'D
sp
GET
sp
THIS
sp
CALCIUM
sp
CHLORIDE
sp
COS
THAT
SEEMS
TO
sp
FORM
sp
PRETTY
sp
EASILY
sp
MHM
THE
OTHER
REACTIONS
sp
WE'VE
sp
HAD
sp
CALCIUM
sp
HYDROXIDE
HYDROGEN
sp
CHLORIDE
sp
YOU
GET
sp
CALCIUM
sp
CHLORIDE
FORMED
sp
AND
YOU
GOT
sp
THIS
sp
THING
sp
WELL
IT'S
QUITE
LIKELY
sp
THAT
sp
THIS
sp
DOES
sp
FORM
sp
INITIALLY
sp
BUT
IT
DOESN'T
sp
LAST
sp
VERY
sp
LONG
sp
AND
IT'S
NOT
VERY
STABLE
AND
IT
sp
RIGHT
SPLITS
UP
sp
SPLITS
UP
sp
INTO
sp
CARBON
DIOXIDE
sp
AND
WATER
sp
MM
sp
ERM
AND
THAT'S
IT
sp
WE'VE
SORTED
sp
OUT
sp
THE
sp
REACTION
sp
SO
sp
JUST
GOING
BACK
sp
TO
THESE
ATES
sp
SULPHATE
sp
HAS
GOT
sp
SULPHUR
AND
OXYGEN
IN
sp
IT
A
sp
CARBONATE
sp
HAS
GOT
sp
WHAT
ER
sp
CARBON
AND
AND
sp
OXYGEN
sp
A
NITRATE
HAS
sp
GOT
sp
NITROGEN
sp
AND
sp
OXYGEN
sp
NOW
A
sp
CHLORIDE
CHLORINE
AND
sp
JUST
sp
THE
sp
THE
METAL
sp
AND
sp
THE
sp
CHLORINE
sp
SO
sp
SODIUM
sp
CHLORIDE
WOULD
sp
JUST
sp
BE
N
sp
A
AND
THEN
C
sp
L
sp
CHLORATE
sp
WOULD
HAVE
CHLORATE
sp
YEAH
sp
CHLORINE
sp
AND
sp
OXYGEN
sp
THAT'S
IT
sp
SO
THERE
IS
A
SYSTEM
sp
BEHIND
ALL
THESE
sp
WEIRD
NAMES
sp
YEAH
sp
THERE'S
A
sp
BIT
OF
A
sp
SYSTEM
sp
ERM
sp
ONCE
YOU
SORT
OF
sp
CRACK
sp
THE
sp
CODE
sp
AND
sp
GET
INTO
sp
IT
sp
THINGS
YOU'VE
NEVER
HEARD
sp
OF
sp
WHEN
sp
THEY
sp
COME
sp
UP
YOU
sp
WHEN
sp
YOU
KNOW
THE
SYSTEM
sp
YOU
THINK
OH
WELL
I
sp
KNOW
sp
WHAT
I
KNOW
sp
WHAT
IT
sp
MEANS
sp
BY
sp
THAT
SO
IF
sp
SOMEONE
SAID
sp
ERM
sp
BROMATE
OR
sp
BROMIDE
sp
SAY
sp
WHAT'S
sp
THE
DIFFERENCE
sp
BETWEEN
sp
CALCIUM
sp
BROMIDE
AND
sp
CALCIUM
sp
BROMATE
sp
WHAT
sp
THE
sp
DIFFERENCE
BE
sp
BROMIDE
sp
IS
sp
JUST
sp
THE
sp
BROMINE
sp
WITH
sp
THE
sp
YEAH
sp
METAL
sp
BROMATE
sp
IS
sp
BROMINE
sp
WITH
sp
THE
sp
OXYGEN
sp
GOOD
SO
IT
sp
MIGHT
sp
BE
sp
IT
sp
MIGHT
BE
SOMETHING
sp
LIKE
sp
B
R
O
sp
THREE
OR
sp
B
sp
R
O
sp
OR
B
R
O
sp
TWO
sp
SOMETHING
LIKE
sp
BUT
IT
WOULD
HAVE
sp
OXYGEN
sp
TO
sp
GO
WITH
sp
IT
sp
SO
sp
YOU'RE
sp
BUILDING
sp
UP
sp
NOW
I
sp
THINK
sp
A
sp
GOOD
UNDERSTANDING
sp
OF
sp
THE
ER
TERMINOLOGY
RIGHT
sp
AND
A
sp
GOOD
UNDERSTANDING
sp
OF
sp
THE
sp
THE
sp
SYSTEMS
AND
sp
PUTTING
THESE
sp
NUMBERS
sp
IN
sp
THE
sp
EQUATIONS
YEAH
sp
SO
AS
YOU
sp
FEEL
HAPPIER
WITH
sp
THAT
sp
YOU'LL
sp
B
sp
MORE
ABLE
sp
TO
sp
PLAY
sp
WITH
sp
THEM
sp
BUT
UNLESS
YOU
DO
PLAY
sp
THEM
sp
FORGET
IT
AGAIN
sp
EXACTLY
sp
IT'LL
sp
BE
COS
sp
WE
LOOKED
AT
sp
THIS
LAST
WEEK
AS
sp
YOU
SAID
sp
AT
sp
THE
END
sp
WHAT
sp
HAPPENS
sp
DRIPPING
ACID
ONTO
sp
ONTO
sp
CHIPS
sp
NOW
sp
THE
sp
THINGS
TO
KNOW
sp
ABOUT
sp
ACIDS
sp
BASES
sp
AND
SALTS
sp
A
METAL
sp
PLUS
sp
AN
sp
ACID
sp
WHAT
sp
HAPPENS
A
sp
METAL
sp
AND
sp
PLUS
sp
AN
sp
ACID
sp
DRIP
sp
METAL
ONTO
sp
AN
ACID
I'M
SORRY
ACID
ONTO
sp
A
sp
METAL
sp
RIGHT
sp
THINK
THAT
sp
MIGHT
BE
A
sp
BIT
sp
DIFFICULT
ER
IT
sp
MIGHT
BE
A
sp
BIT
sp
AWKWARD
IF
sp
YOU
IT
MIGHT
BE
sp
HIGHLY
REACTIVE
IF
YOU
sp
DROPPED
sp
MOLTEN
sp
METAL
sp
ONTO
sp
IT
ERM
sp
IT
sp
REACTS
AND
sp
PRODUCES
CARBON
DIOXIDE
sp
MM
sp
WOULD
sp
IT
NO
sp
A
METAL
WITH
AN
sp
ACID
IT'S
sp
A
sp
METAL
sp
ERM
sp
ERM
IT
EFFERVESCES
sp
RIGHT
sp
SO
sp
THERE'S
sp
A
sp
GAS
sp
GIVEN
sp
OFF
sp
WHICH
IS
sp
CARBON
sp
DIOXIDE
sp
HYDROGEN
sp
OKAY
sp
RIGHT
sp
SO
sp
THERE'S
A
S
sp
THERE'S
A
SYSTEM
sp
TO
WHAT'S
sp
GOING
sp
ON
sp
WITH
THE
ACIDS
sp
AND
IT'S
NOT
sp
JUST
sp
ONE
sp
ACID
sp
LIKE
sp
HYDROCHLORIC
sp
MOST
sp
OF
THE
ACIDS
sp
WILL
DO
sp
IT
SOME
OF
THEM
DO
IT
VERY
sp
READILY
sp
SOME
OF
THEM
sp
YOU
HAVE
sp
TO
GET
sp
THE
sp
CONDITIONS
RIGHT
OFTEN
sp
YOU
sp
HAVE
sp
TO
GET
sp
THE
TEMPERATURE
sp
HIGH
sp
TO
sp
MAKE
IT
sp
TO
sp
MAKE
sp
THE
REACTION
sp
GO
sp
BUT
A
METAL
sp
PLUS
AN
sp
ACID
sp
ERM
sp
THERE'S
A
sp
TYPICAL
sp
ONE
sp
ZINC
sp
H
TWO
S
sp
O
sp
FOUR
sp
GIVES
sp
ZINC
SULPHATE
sp
AND
THE
sp
HYDROGEN
sp
YEAH
sp
AND
YOU
CAN
sp
THINK
OF
THAT
sp
PRETTY
EASILY
IF
YOU
LOOK
AT
YOUR
sp
TABLE
sp
ERM
sp
JUST
sp
WRITE
sp
DOWN
sp
WITH
sp
THE
sp
CHARGES
ON
sp
THE
sp
THE
sp
IONS
sp
WHAT
sp
H
TWO
S
O
sp
FOUR
LOOKS
sp
LIKE
sp
H
sp
TWO
S
O
FOUR
RIGHT
sp
ERM
sp
WHAT'S
sp
THE
sp
CHARGE
sp
ON
THAT
sp
H
sp
POSITIVE
sp
RIGHT
sp
GOOD
sp
ER
sp
DOUBLE
NEGATIVE
YEAH
sp
GREAT
sp
HOW
DID
YOU
WORK
sp
THAT
OUT
sp
ER
THE
sp
HS
sp
ARE
POSITIVE
sp
RIGHT
sp
YEAH
AND
sp
THERE'S
TWO
OF
IT
sp
SO
sp
THAT
sp
GOOD
SO
THAT
WAS
I
LIKE
THAT
BECAUSE
YOU
WORKED
IT
OUT
sp
YOU
DIDN'T
sp
LOOK
IT
WITH
sp
TABLE
YOU
YEAH
sp
GOOD
sp
SO
IT'S
H
TWO
S
sp
O
sp
FOUR
sp
PLUS
ERM
sp
A
METAL
sp
ERM
sp
CHOSE
sp
ZINC
sp
THEN
sp
SHALL
WE
TRY
IT
NO
WE'LL
USE
ZINC
sp
YEAH
sp
HAVE
sp
YOU
GOT
IT
sp
IN
sp
HERE
sp
NO
NO
sp
OKAY
sp
WE'LL
USE
ERM
sp
YEAH
sp
ZINC
ION
sp
RIGHT
sp
Z
N
sp
TWO
sp
PLUS
sp
RIGHT
sp
THOUGHT
IT
SHOULD
sp
BE
IN
sp
THERE
sp
COS
sp
IT'S
sp
NORMALLY
OKAY
NOW
ALL
sp
THAT
HAPPENS
sp
HERE
IF
YOU
sp
IF
YOU
THINK
OF
IT
sp
GOING
BACK
sp
TO
THE
sp
PICTURE
WITH
sp
THE
sp
THE
sp
MAGNETS
OR
sp
THE
ELECTROSTATIC
sp
CHARGES
sp
OR
OR
sp
BONDS
WHATEVER
YOU
sp
LIKE
sp
TO
sp
THINK
OF
IT
YEAH
sp
YOU'VE
GOT
AN
S
O
sp
FOUR
sp
WITH
sp
TWO
sp
BONDS
sp
ON
IT
sp
AND
IT'S
HOLDING
sp
ON
TO
A
sp
HYDROGEN
sp
YEAH
IN
EACH
sp
ONE
sp
AND
THE
ZINC
COMES
sp
ALONG
AND
sp
PUSHES
THE
HYDROGEN
OUT
IT
sp
SAYS
sp
HANG
sp
ON
sp
I
WANT
sp
THAT
SULPHATE
sp
YEAH
sp
AND
IT
sp
DISPLACES
THE
sp
HYDROGEN
AND
sp
THAT
sp
WE
sp
THAT'S
sp
WHY
WE
DESCRIBE
sp
IT
sp
THE
sp
THE
ZINC
sp
DISPLACES
sp
THE
sp
HYDROGEN
sp
FROM
THE
ACID
sp
SO
sp
ZINC
SULPHATE
sp
GETS
sp
FORMED
sp
THE
ZIL
sp
THE
ZINC
sp
JUST
GOES
IN
IN
sp
PLACE
sp
OF
sp
THAT
sp
H
TWO
sp
SO
IT
sp
BECOMES
sp
Z
N
sp
S
sp
O
sp
FOUR
AND
THE
sp
TWO
sp
HS
sp
THAT
sp
GOT
sp
PUSHED
OUT
H
sp
TWO
sp
YEAH
sp
YEAH
H
TWO
sp
AND
THE
sp
CHARGE
sp
ERM
sp
NOW
AH
AH
sp
HANG
sp
ON
sp
YEAH
sp
THIS
IS
sp
THIS
ONE
IS
A
BIT
sp
TRICKY
BECAUSE
THAT
sp
IS
sp
NOT
sp
A
ZINC
sp
ION
sp
THAT'S
sp
ZINC
sp
JUST
ON
ITS
sp
OWN
sp
SO
sp
IT'S
JUST
sp
Z
N
sp
RIGHT
sp
ERM
IT
WANTS
TO
sp
BE
A
Z
N
sp
DOUBLE
sp
POSITIVE
sp
AND
GO
WITH
THE
SULPHATE
YEAH
sp
IF
YOU
LIKE
sp
SO
IT
sp
PINCHES
sp
THE
TWO
POSITIVE
sp
CHARGES
sp
OFF
sp
THE
HYDROGEN
sp
COS
IN
THESE
EQUATIONS
sp
THE
sp
CHARGES
sp
MUST
sp
MUST
sp
BALANCE
sp
AS
WELL
sp
SO
sp
THAT
sp
IF
sp
YOU
JUST
sp
CROSS
sp
THE
sp
DOUBLE
sp
POSITIVE
sp
OUT
sp
YOU
NEED
TO
YOU
sp
CAN'T
WRITE
IT
IN
BUT
sp
YOU
NEED
TO
sp
REMEMBER
THAT
sp
IT
sp
WANTS
TO
sp
BECOME
A
sp
DOUBLE
sp
POSITIVE
sp
GIVEN
YEAH
THE
CHANCE
sp
SO
sp
THE
ZINC
sp
COMES
ALONG
sp
PUSHES
THE
HYDROGEN
sp
OUT
sp
TAKES
ITS
TWO
CHARGES
sp
OFF
sp
IT
AS
WELL
sp
RIGHT
sp
AND
sp
YOU'RE
LEFT
sp
WITH
H
TWO
sp
SO
sp
THAT'S
sp
THE
sp
FIRST
SORT
OF
REACTION
sp
WITH
sp
WITH
ACIDS
sp
A
sp
METAL
sp
PLUS
sp
AN
ACID
AND
sp
MOST
OF
THE
METALS
AND
sp
MOST
OF
THE
ACIDS
LL
sp
GIVE
sp
YOU
HYDROGEN
sp
SOME
OF
sp
THEM
sp
YOU
REMEMBER
THE
sp
TABLE
WE
HAD
A
LONG
sp
TIME
AGO
sp
SHOWING
THE
sp
REACTIVITY
OF
sp
DIFFERENT
ELEMENTS
sp
PARTICULARLY
THE
METALS
sp
WHEN
WE
WERE
LOOKING
AT
sp
METALS
sp
ERM
sp
SOME
sp
METALS
sp
ARE
MUCH
sp
MORE
REACTIVE
THAN
sp
OTHERS
sp
I
MEAN
SOME
sp
SOME
METALS
sp
WITH
sp
AN
ACID
A
sp
FAIRLY
sp
WEAK
ACID
sp
WILL
GIVE
YOU
HYDROGEN
sp
SOME
METALS
sp
WILL
GIVE
YOU
sp
HYDROGEN
sp
JUST
sp
WITH
sp
S
sp
WATER
OR
WITH
sp
STEAM
sp
AND
SOME
OF
THEM
sp
IT'S
sp
IT'S
sp
HARD
TO
GET
sp
THEM
TO
GO
sp
SO
sp
BUT
IN
GENERAL
sp
ANY
OF
THE
sp
FAIRLY
REACTIVE
sp
ACIDS
AND
ANY
OF
sp
THE
FAIRLY
REACTIVE
sp
METALS
sp
THEY'RE
GOING
TO
sp
GIVE
YOU
sp
A
SALT
sp
AND
sp
HYDROGEN
sp
SO
sp
METAL
sp
PLUS
ACID
sp
GIVES
YOU
A
sp
SALT
sp
AND
HYDROGEN
sp
AND
sp
YOU
sp
CAN
DO
THAT
THEN
WE'VE
sp
GOT
sp
A
BASE
sp
PLUS
AN
ACID
sp
WHAT'S
THE
DIFFERENCE
AGAIN
BETWEEN
A
sp
BASE
sp
AND
AN
ALKALI
sp
A
BASE
MM
sp
IS
NEUTRAL
sp
NO
A
sp
BASE
sp
IS
AN
ALKALI
A
sp
BASE
sp
YEAH
YEAH
sp
OKAY
A
BASE
SO
WHAT'S
sp
SO
SPECIAL
ABOUT
AN
ALKALI
sp
THAT'S
sp
NOT
sp
QUITE
sp
A
SPECIAL
sp
ABOUT
A
BASE
sp
ERM
sp
ERM
sp
AN
ALKALI
IS
A
BASE
sp
BUT
A
sp
BASE
sp
ISN'T
sp
AN
sp
ALKALI
sp
HEY
sp
YEAH
sp
ERM
sp
AN
ALKALI
IS
sp
CONTAINED
IN
sp
THE
BASE
FAMILY
sp
BUT
IT'S
GOT
A
sp
SPECIAL
sp
PROPERTY
sp
ERM
sp
IT'S
A
sp
FAIRLY
SIMPLE
sp
PHYSICAL
sp
PROPERTY
sp
ACTUALLY
sp
BUT
sp
THEY'RE
THEY'RE
sp
SOLUBLE
sp
RIGHT
sp
SO
sp
MM
sp
BUT
sp
THIS
THING
WE'VE
BEEN
DOING
sp
WITH
AN
ACID
AND
AN
ALKALI
sp
MOST
OF
THE
sp
BASES
sp
WILL
DO
IT
sp
AS
sp
WELL
sp
YEAH
sp
SO
sp
LET'S
TRY
THAT
ONE
sp
NOW
THE
BASE
sp
IS
ERM
sp
MOST
sp
OF
THE
OXIDES
ARE
sp
BASES
sp
THE
METAL
OXIDES
sp
SO
sp
WHAT
WOULD
sp
MAGNESIUM
OXIDE
sp
LOOK
sp
LIKE
AND
sp
WHAT'S
GOING
TO
HAPPEN
sp
IF
sp
WE
sp
GET
IT
sp
TO
REACT
sp
WITH
sp
H
TWO
S
sp
O
sp
FOUR
sp
SO
TRY
THAT
ONE
sp
H
TWO
S
sp
O
sp
FOUR
sp
PLUS
sp
MAGNESIUM
sp
OXIDE
sp
WHAT'S
sp
THAT
sp
GOING
sp
TO
sp
BE
sp
M
G
OXIDE
sp
IS
SO
sp
THAT'S
A
sp
DOUBLE
sp
POSITIVE
sp
A
sp
DOUBLE
sp
NEGATIVE
sp
THAT'S
A
sp
POSITIVE
DOUBLE
sp
NEGATIVE
sp
SO
H
TWO
sp
AND
sp
THE
O
sp
SO
sp
THAT'S
sp
GON
sp
NA
sp
BE
sp
THAT'LL
BE
A
DOUBLE
POSITIVE
sp
BECAUSE
THERE'S
TWO
sp
OF
sp
IT
sp
WOULDN'T
sp
IT
IT'S
IT'S
WELL
sp
YEAH
sp
ERM
sp
YOU
WOULDN'T
WRITE
IT
LIKE
THAT
BUT
YOU'D
WRITE
IT
AS
A
SINGLE
POSITIVE
sp
OKAY
NOW
BECAUSE
sp
THERE'S
A
TWO
BUT
BECAUSE
THERE'S
TWO
OF
IT
DOWN
sp
THERE
sp
YOU'VE
GOT
sp
TWO
YEAH
NEGATIVE
TWO
sp
POSITIVE
THAT'S
HOOKS
sp
ON
sp
IT
H
sp
TWO
sp
O
PLUS
sp
S
sp
O
FOUR
ERM
sp
THAT'S
A
DOUBLE
sp
NEGATIVE
sp
SO
sp
THE
sp
GOES
sp
THERE
SO
sp
MAGNESIUM
sp
M
sp
G
S
sp
O
FOUR
sp
LET'S
HAVE
A
LOOK
sp
OH
sp
THAT'S
A
SHAME
sp
WHAT
sp
WAS
GOING
TO
SAY
CHECK
IT
IN
THE
BOOK
sp
BUT
I
GAVE
YOU
sp
WRONG
sp
ONE
sp
NEVER
MIND
sp
OKAY
I'LL
DO
THE
OTHER
ONE
OKAY
sp
CHECK
IT
YEAH
OKAY
TRY
THE
OTHER
sp
ONE
THEN
sp
ERM
AN
EASIER
sp
ONE
IN
FACT
ERM
MAGNESIUM
OXIDE
sp
WITH
sp
HYDROCHLORIC
ACID
sp
M
G
sp
OXIDE
sp
WHICH
sp
IS
sp
O
RIGHT
sp
WITH
sp
HYDROCHLORIC
sp
ACID
sp
H
sp
C
sp
L
AND
sp
THAT'S
sp
A
sp
DOUBLE
sp
POSITIVE
sp
RIGHT
sp
DOUBLE
NEGATIVE
sp
GOOD
sp
THAT'S
sp
A
sp
SINGLE
sp
POSITIVE
RIGHT
THAT'S
sp
A
NEGATIVE
RIGHT
sp
RIGHT
sp
AND
sp
WHAT'S
sp
GOING
TO
HAPPEN
sp
WHAT
WAS
sp
THE
FIRST
sp
WAY
sp
YOU
sp
CAN
sp
SEE
sp
MAGNESIUM
sp
CHLORIDE
sp
WELL
TRY
THE
THE
sp
ONE
YOU
sp
TRIED
sp
IN
sp
THE
FIRST
EQUATION
OH
YEAH
sp
WE
DID
sp
OXYGEN
AND
sp
A
sp
HYDROGEN
RIGHT
sp
SO
sp
WHAT
HAVE
sp
WE
GET
sp
WE'VE
sp
GOT
ONE
O
NEGATIVE
sp
SO
sp
THAT'LL
sp
BE
sp
H
sp
O
ERM
TWO
sp
O
sp
YEAH
sp
THAT'S
sp
THE
H
TWO
O
sp
WHERE
DID
THE
sp
TWO
HS
sp
COME
sp
FROM
YOU'VE
ONLY
sp
GOT
sp
ONE
THERE
ER
sp
YOU'LL
ADD
sp
ANOTHER
sp
OKAY
PUT
sp
A
PUT
sp
A
sp
TWO
IN
sp
FRONT
NOW
sp
AND
WHAT'S
THAT
sp
GOING
sp
TO
sp
GIVE
sp
YOU
sp
TWO
sp
THAT'S
GOING
sp
TO
sp
BECOME
sp
A
DOUBLE
sp
SO
IT'S
GOING
TO
GIVE
YOU
TWO
HS
sp
AND
TWO
C
LS
TWO
C
LS
sp
SO
sp
THAT'LL
sp
BE
sp
H
TWO
O
sp
PLUS
sp
MAGNESIUM
sp
CHLORINE
sp
SO
THAT'S
sp
A
M
G
sp
C
L
sp
TWO
sp
BRILLIANT
sp
GO
ON
sp
SEE
IF
THAT'S
sp
WELL
I'M
SAYING
SO
sp
SEE
IF
THAT'S
WHAT
IT
GIVES
IN
THE
sp
BOOK
sp
M
sp
G
sp
O
sp
IT
sp
JUST
sp
SAYS
sp
IT'S
sp
AQUEOUS
sp
BUT
sp
BUT
sp
I
MEAN
sp
WHEN
IT
sp
WHEN
IT
sp
WHEN
IT
HAPPENS
sp
YEAH
sp
BECAUSE
sp
MAGNESIUM
sp
CHLORIDE
IS
sp
SOLUBLE
IT'LL
sp
BE
DISSOLVED
IN
sp
THE
WATER
AND
sp
YOU'LL
sp
FINISH
sp
UP
WITH
sp
A
SOLUTION
sp
OF
sp
MAGNESIUM
sp
CHLORIDE
sp
THAT'S
sp
IT
SO
sp
METAL
sp
AND
ACID
sp
GIVES
WHAT
A
sp
METAL
sp
AND
sp
AN
sp
ACID
sp
GIVES
ERM
ER
WATER
AND
sp
THIS
IS
THE
ONE
sp
THAT
DOESN'T
GIVE
sp
WATER
OH
sp
YEAH
ER
WHAT
DID
THE
ZINC
sp
DO
TO
THE
HYDROGEN
CARBON
DIOXIDE
AND
sp
HANG
ON
HANG
sp
ON
sp
METAL
AND
ACID
sp
SAY
sp
THINK
OF
THE
ZINC
sp
AND
sp
WHICH
sp
ACID
sp
WAS
sp
IT
sp
WE
USED
sp
H
TWO
S
sp
O
FOUR
sp
WHAT
DID
THE
ZINC
sp
DO
sp
TO
THE
sp
HYDROGEN
ER
sp
IT
sp
PINCHED
sp
ITS
sp
GOOD
sp
GO
ON
sp
IT
sp
WHAT
DID
IT
DO
RIGHT
IT
PINCHED
ITS
sp
POSITIVES
ITS
sp
ELECTRONS
sp
RIGHT
sp
IT
sp
PINCHED
ITS
sp
PLACE
AND
IT
sp
PINCHED
sp
ITS
CHARGE
IT
sp
DISPLACED
IT
sp
IT
sp
PINCHED
IT
OUT
sp
OF
ITS
sp
NICE
sp
COSY
RELATIONSHIP
SO
YOU
GET
HYDROGEN
sp
AND
sp
IT
LIBERATED
sp
THE
sp
HYDROGEN
sp
OKAY
sp
SO
THAT'S
AN
ACID
sp
PLUS
A
sp
METAL
sp
NOW
sp
AN
ACID
sp
PLUS
A
sp
BASE
sp
WHICH
IS
sp
THIS
ONE
sp
WE'VE
sp
JUST
sp
DONE
sp
A
METAL
OXIDE
sp
THE
sp
METAL
OXIDES
ARE
sp
BASES
sp
ER
sp
YOU
CAN
THINK
OF
THEM
AS
sp
BEING
sp
ALKALINE
sp
WE
CALL
IT
sp
BASIC
sp
BUT
sp
VERY
sp
VERY
SIMILAR
sp
SORT
OF
THING
TO
ALKALINE
sp
OKAY
sp
SO
sp
WHAT
HAPPENS
WITH
A
sp
BASE
AND
sp
AN
ACID
sp
WITH
sp
A
sp
BASE
sp
AND
sp
AN
sp
ACID
sp
WELL
sp
WHAT
sp
HAPPENS
WITH
AN
ACID
AND
AN
sp
ALKALI
sp
ER
ACID
AND
ALKALI
ER
IT
GIVES
A
WATER
AND
sp
SAL
sp
RIGHT
sp
GREAT
sp
AND
WHAT
HAPPENS
WHAT
SEEMS
TO
BE
HAPPENING
WITH
A
sp
BASE
sp
AND
AN
ACID
sp
OR
AN
ACID
AND
sp
A
sp
BASE
ERM
sp
GIVES
OFF
sp
HYDROGEN
sp
AH
NO
sp
GIVES
OFF
IT
sp
GIVES
YOU
WELL
THIS
IS
sp
ERM
THIS
IS
ONE
sp
THAT
sp
YOU
DID
sp
HERE
IT
GIVES
OFF
sp
WATER
sp
THIS
sp
IS
ONE
YOU
DID
sp
HERE
sp
YEAH
sp
YOU
GET
sp
WATER
sp
AND
sp
ER
ER
sp
THE
sp
METAL
sp
CHLORIDE
sp
MAGNESIUM
CHLORIDE
IN
THIS
sp
CASE
sp
IN
sp
THIS
CASE
YOU
sp
GOT
sp
A
CHLORIDE
sp
IF
sp
YOU'D
USED
sp
SODIUM
sp
YOU
sp
WOULD
sp
HAVE
sp
GOT
sp
SODIUM
CHLORIDE
WHICH
IS
ER
OH
sp
RIGHT
SALT
sp
SO
sp
THIS
sp
IS
sp
MAGNESIUM
sp
CHLORIDE
IS
sp
ALSO
A
sp
ER
sp
SALT
sp
RIGHT
sp
SO
sp
WE
TRIED
COULDN'T
EAT
IT
sp
THOUGH
ACID
AND
A
sp
BASE
sp
MM
ACID
AND
A
sp
BASE
sp
AND
WE
GET
sp
SALT
sp
AND
sp
WATER
sp
TRY
sp
ALKALI
AND
A
sp
BASE
YOU
sp
GET
sp
SALT
sp
AND
WATER
SO
THEY'RE
VERY
SIMILAR
sp
REACTION
sp
THE
sp
BASE
AND
sp
THE
ACID
AND
THE
ALKALI
sp
AND
THE
sp
ACID
sp
THEY'RE
THE
SAME
SORT
sp
OF
sp
THING
sp
THEY'RE
sp
NEUTRALIZING
sp
EACH
sp
OTHER
sp
AND
sp
THE
OTHER
ONE
WITH
sp
THE
sp
CARBONATE
WHAT
sp
HAPPENED
sp
THEN
sp
THE
ONE
sp
YOU
sp
ER
WORKED
sp
OUT
sp
YOURSELF
sp
THE
sp
CARBON
sp
WHICH
ONE
WAS
THAT
ERM
sp
COS
sp
THERE'S
SO
MANY
OF
sp
THEM
NOW
I'M
sp
GETTING
sp
A
BIT
I
KNOW
sp
AND
I'M
TRYING
TO
sp
PILE
sp
THEM
UP
NOW
AND
LET
YOU
SEE
THE
sp
PATTERNS
SO
THESE
sp
THE
sp
CARBONATE
I
CAN'T
REMEMBER
WHAT
IT
IS
I'M
GETTING
CONFUSED
I
OKAY
sp
RIGHT
sp
YOU
MENTIONED
IT
A
sp
FEW
MINUTES
AGO
sp
YOU
sp
SUGGESTED
THAT
sp
THIS
sp
THING
sp
WAS

FORMED
sp
WHICH
ONE

WA
I
I
sp
CAN'T

I
WAS

BACK
AT
THE
CARBONATES
sp
SO
YOU'VE
sp
SORTED
OUT
YOUR
CALCIUM
sp
CHLORIDE
AND
sp
YOU'VE
GOT
THIS
sp
HORRIBLE
LOOKING
sp
THING
sp
H
TWO
sp
C
O
THREE
sp
RIGHT
sp
BUT
sp
WE
KNOW
sp
THIS
IS
sp
MARBLE
sp
CHIPPINGS
sp
YOU
KNOW
YOU
WERE
GETTING
sp
THIS
CARBON
sp
DIOXIDE
sp
OFF
sp
HOW
COULD
YOU
TELL
IT
sp
WAS
CARBON
sp
DIOXIDE
sp
WHAT
sp
TESTS
C
sp
COULD
YOU
sp
DO
sp
TO
IT
sp
ERM
IF
sp
IT'S
CARBON
DIOXIDE
IT'LL
sp
REACT
sp
WITH
LIME
sp
WATER
sp
WOULDN'T
IT
YEAH
MAKE
CLEAR
LIME
sp
WATER
CLOUDY
sp
RIGHT
sp
THAT'S
IT
sp
MAKES
IT
sp
MILKY
sp
AND
sp
IT
WILL
PUT
OUT
A
sp
GLOWING
sp
SPLINT
sp
OR
SOMETHING
sp
SO
IF
sp
THERE
W
sp
WELL
sp
WE'VE
GOT
sp
TO
GET
sp
CARBON
sp
DIOXIDE
OUT
OF
sp
THIS
SOMEHOW
sp
COS
WE
KNOW
CARBON
sp
DIOXIDE
sp
IS
GIVEN
OFF
sp
SO
sp
YOU'RE
DOING
A
BIT
OF
sp
DETECTIVE
sp
WORK
HERE
sp
WHAT
sp
MUST
BE
HAPPENING
sp
IN
THIS
sp
WELL
LET'S
sp
TAKE
sp
CARBON
sp
DIOXIDE
sp
OUT
OF
THAT
AND
WHAT
sp
DO
YOU
GET
sp
WELL
sp
OUT
OF
THAT
sp
YOU'VE
sp
GOT
ALL
THE
MAKINGS
sp
THERE
OF
sp
CARBON
sp
DIOXIDE
AND
sp
WATER
sp
SO
MM
sp
GIVES
US
sp
THE
OTHER
sp
THING
THAT
sp
HAPPENS
sp
WITH
THEM
sp
THAT
ER
sp
AN
sp
ACID
sp
PLUS
sp
A
sp
CARBONATE
sp
GIVES
YOU
sp
CARBON
DIOXIDE
sp
AS
sp
WELL
AS
sp
A
SALT
sp
AND
sp
WATER
sp
RIGHT
AND
THAT'S
sp
THAT'S
ABOUT
sp
IT
sp
FOR
THE
ACIDS
sp
IT
ALSO
sp
BRINGS
IN
sp
THE
sp
BASES
sp
THE
sp
THE
BASIC
sp
THE
sp
BASES
sp
AND
THE
ALKALIS
sp
IF
YOU
KNOW
THAT
sp
LOT
sp
JUST
sp
THERE
sp
YOU
CAN
sp
PROBABLY
sp
GET
sp
THROUGH
sp
ABOUT
sp
OOH
sp
EIGHTY
PERCENT
sp
OF
sp
YOUR
CHEMISTRY
sp
YEAH
AT
sp
LEAST
SEVENTY
sp
FIVE
sp
PERCENT
sp
YOU
CAN
sp
WORK
OUT
WELL
sp
WHAT
HAVE
WE
GOT
sp
WE
GOT
sp
AN
sp
ACID
OR
A
sp
BASE
sp
OR
sp
A
CARBONATE
OR
sp
WHAT
sp
AND
sp
DOES
IT
sp
FIT
ANY
OF
THE
sp
I
MEAN
THERE
AREN'T
MANY
sp
PATTERNS
sp
THERE'S
METAL
ACID
sp
WHAT
DOES
THAT
sp
GIVE
sp
METAL
sp
AND
sp
ACID
sp
YEAH
ER
sp
CARBON
DIOXIDE
sp
NO
sp
ER
sp
OH
sp
I'M
GETTING
CONFUSED
NOW
sp
THERE'S
THAT
MANY
OF
THEM
THAT
I
KNOW
I
KNOW
I
KNOW
sp
BUT
I
WANT
TO
JUST
KEEP
GOING
ROUND
THE
LOT
sp
METAL
sp
AND
AN
sp
ACID
IT
MIGHT
HELP
sp
IF
YOU
WRITE
sp
THEM
sp
NAH
sp
I
DON'T
THINK
IT
IS
I
L
IT'S
JUST
REMEMBERING
THEY'RE
ALL
sp
DIFFERENT
AND
I
RIGHT
THEY'RE
ALL
DIFFERENT
BUT
THEY'RE
SIMILAR
ENOUGH
TO
BE
A
BIT
CONFUSING
sp
SO
sp
RIGHT
OKAY
OKAY
IT
EFFERVESCES
WITH
IT
sp
AND
IT
sp
GIVES
OFF
sp
OH
SHIT
sp
OKAY
sp
RIGHT
CAN
I
LOOK
BACK
AND
NO
NO
NO
NO
NO
sp
WORK
IT
OUT
OH
sp
FUCKING
HELL
WORK
IT
OUT
IT'S
GETTING
TOO
CONFUSING
I'VE
GOT
TO
TRY
IT
COS
IF
I
JUST
YEAH
YEAH
NO
sp
NO
YOU'VE
KEEP
ON
WORKING
IT
OUT
sp
I
WON'T
REMEMBER
IT
sp
SO
sp
YOU'VE
GOT
sp
WHAT
HAVE
WE
GOT
sp
WE'VE
GOT
sp
A
METAL
sp
THE
ONE
WE
USED
WAS
sp
ZINC
sp
YEAH
sp
Z
N
sp
PLUS
sp
AN
ACID
sp
LET'S
USE
sp
H
C
L
H
sp
C
L
AND
WHAT
HAPPENED
sp
REMEMBER
WHAT
HAPPENED
sp
WHAT
sp
WHAT
DID
sp
WELL
WHAT
sp
WHAT'S
GOING
TO
GET
sp
FORMED
sp
WITH
sp
ZINC
sp
AND
sp
CHLORINE
ABOUT
sp
ZINC
sp
CHLORIDE
sp
RIGHT
sp
OKAY
sp
TAKE
ZINC
CHLORIDE
OUT
sp
OF
THAT
sp
TAKE
sp
THE
ZINC
AND
THE
sp
CHLORINE
sp
AWAY
AND
sp
WHAT
HAVE
YOU
GOT
LEFT
WITH
sp
HYDROGEN
sp
OKAY
sp
YEAH
sp
SO
YOU
DIDN'T
REMEMBER
IT
sp
YOU
WORKED
IT
OUT
sp
NOW
sp
YOU
YOU'RE
VERY
KEEN
ON
REMEMBERING
EVERYTHING
sp
YOU
CAN'T
REMEMBER
EVERYTHING
YEAH
BECAUSE
IF
I
WORK
IT
OUT
I'LL
JUST
KNOW
THAT
I
IT
MADE
SO
AND
SO
BUT
I
WON'T
KNOW
THAT
sp
IT
sp
GAVE
OFF
sp
THAT
I'LL
JUST
sp
REMEMBER
THAT
IT
MADE
LIKE
sp
ZINC
CHLORIDE
sp
OR
SOMETHING
I
WON'T
REMEMBER
sp
IF
I
I'LL
JUST
REMEMBER
THE
SYMBOL
sp
I
WON'T
EVEN
REMEMBER
THE
SYMBOLS
BUT
I'LL
JUST
KNOW
sp
THAT
I
sp
CAN
WORK
IT
OUT
IF
I
NEEDED
TO
sp
NOT
sp
I
WON'T
REMEMBER
sp
THE
ANSWER
sp
OKAY
I
sp
MEAN
sp
THE
QUESTION
ON
THE
PAPER
MIGHT
sp
WELL
BE
sp
WHAT
HAPPENS
sp
WHEN
sp
A
METAL
sp
REACTS
sp
WITH
sp
AN
ACID
sp
YEAH
NOT
ANY
PARTICULAR
ONE
sp
SO
THEN
YOU'VE
GOT
TO
sp
THINK
sp
WELL
sp
I
DON'T
sp
KNOW
sp
CAN'T
REMEMBER
sp
WELL
LET'S
TRY
IT
WHAT
sp
WOULD
HAPPEN
LET'S
TRY
sp
ZINC
sp
MAYBE
YOU'LL
sp
VAGUELY
REMEMBER
sp
WE
sp
TRIED
sp
ZINC
sp
AND
HYDROCHLORIC
sp
MM
YEAH
sp
WHAT
WOULD
HAPPEN
sp
WELL
sp
YOU'RE
ALMOST
CERTAINLY
GOING
sp
TO
GET
sp
THE
sp
ZINC
sp
CHLORIDE
sp
AND
WHAT
HAVE
YOU
GOT
LEFT
sp
HYDROGEN
sp
AH
sp
SO
sp
WHAT
HAPPENS
sp
WITH
sp
ANY
ACID
AND
ANY
METAL
sp
WITH
A
MES
sp
A
sp
METAL
sp
AND
sp
AN
ACID
sp
YOU'RE
GOING
TO
GET
sp
A
sp
SALT
sp
AND
sp
HYDROGEN
GIVEN
sp
OFF
sp
SO
sp
THIS
IS
sp
YEAH
THIS
IS
YOUR
WAY
OF
sp
WORKING
sp
BACK
sp
RATHER
THAN
TRY
AND
REMEMBER
EVERY
sp
LITTLE
DETAIL
sp
BECAUSE
sp
A
LOT
OF
THEM
ARE
sp
SIMILAR
sp
EASY
TO
GET
sp
CONFUSED
BETWEEN
THEM
BUT
YOU
sp
THINK
sp
WELL
sp
HEY
sp
WHAT
WOULD
HAPPEN
sp
WHAT
HAPPENS
sp
WITH
sp
AN
ACID
AND
sp
A
BASE
sp
WHAT
HAPPENS
sp
WITH
AN
ACID
AND
sp
AN
ALKALI
NOW
sp
THOSE
sp
TWO
ARE
sp
VIRTUALLY
sp
IDENTICAL
THEY
sp
THEY
ARE
MORE
OR
LESS
sp
IDENTICAL
WHAT
sp
WHAT
MM
HAPPENS
sp
THERE
sp
WITH
sp
AN
sp
ACID
sp
AND
sp
A
sp
BASE
sp
WELL
sp
THE
EASIEST
sp
ONE
sp
PERHAPS
IS
sp
WHAT
HAPPENS
WITH
AN
ACID
AND
AN
ALKALI
sp
ERM
sp
YOU
GET
A
sp
WATER
AND
A
SALT
sp
RIGHT
sp
NOW
YOU
DIDN'T
NEED
sp
TO
GO
sp
DID
YOU
NEED
TO
GO
BACK
TO
REMEMBER
ANY
NO
sp
SPECIFIC
sp
ONES
sp
NO
sp
NO
sp
AND
THE
SAME
THING
HAPPENS
sp
WITH
A
BASE
sp
WATER
AND
SALT
sp
WATER
sp
AND
A
sp
SALT
sp
AND
THEN
THE
OTHER
sp
THING
sp
IS
sp
WHAT
HAPPENS
WITH
A
sp
CARBONATE
sp
AND
AN
sp
ACID
ERM
CARBON
DIOXIDE
sp
RIGHT
sp
AND
ER
HYDROGEN
sp
NO
CARBON
sp
DIOXIDE
sp
WATER
sp
YEAH
sp
AND
AND
sp
YOU'VE
YOU'VE
sp
WORKED
IT
YOU'VE
WORKED
IT
OUT
OVER
HERE
sp
AND
sp
YEAH
AND
WHAT
sp
DID
sp
YOU
DO
YOU
GOT
THIS
HORRIBLE
LOOKING
sp
THING
sp
AND
WE
SAID
OH
sp
THAT
DOESN'T
sp
HAPPEN
sp
BECAUSE
WE
KNOW
WE'VE
GOT
CARBON
DIOXIDE
sp
OH
ER
sp
YOU
MEAN
BUT
YOU'D
ALREADY
TAKEN
OUT
IT
MADE
sp
YEAH
I
KNOW
IT
MADE
THAT
sp
BUT
sp
I
sp
THOUGHT
YOU
JUST
WANTED
TO
KNOW
WHAT
IT
GAVE
OFF
sp
OH
OKAY
WHAT
EVERY
EVERYTHING
THAT'S
sp
MADE
sp
SO
IT'S
sp
CALCIUM
sp
CHLORIDE
RIGHT
sp
SO
sp
THERE'S
A
sp
SALT
sp
AND
sp
THE
sp
CARBON
sp
DIOXIDE
sp
AND
THE
sp
A
AND
sp
THE
sp
WATER
WATER
sp
SO
sp
IF
sp
YOU
sp
WANT
TO
JUST
SORT
OF
sp
REMEMBER
THEM
ALL
sp
AS
A
TABLE
WE'VE
sp
GOT
sp
SORT
OF
sp
SAY
sp
ACID
sp
PLUS
sp
METAL
sp
AND
SEE
sp
WHAT
HAPPENS
sp
SEE
sp
WHAT'S
sp
GIVEN
OFF
sp
WELL
sp
WE
GET
A
SALT
sp
A
sp
LOT
OF
sp
THE
sp
TIME
sp
DON'T
sp
WE
sp
AND
WE
YEAH
GET
sp
WATER
A
sp
LOT
sp
OF
sp
THE
TIME
sp
SO
sp
ERM
sp
SALT
WATER
sp
HYDROGEN
sp
CARBON
sp
DIOXIDE
sp
YEAH
sp
CAN
sp
YOU
REMEMBER
WHAT
HAPPENS
WITH
sp
THE
METAL
sp
ERM
ACID
AND
THE
METAL
sp
WHAT
sp
DID
sp
WE
GET
sp
ACID
sp
AND
sp
METAL
IT
sp
GIVES
OFF
sp
HYDROGEN
sp
RIGHT
sp
OKAY
sp
SO
IT'S
sp
HYDROGEN
sp
AND
sp
ERM
sp
SALT
sp
RIGHT
sp
BRILLIANT
sp
ACID
sp
PLUS
sp
AN
ALKALI
sp
THAT'S
sp
ABOUT
THE
EASIEST
sp
ONE
sp
THAT'S
ER
SALT
AND
sp
WATER
sp
RIGHT
ACID
sp
PLUS
sp
ALKALI
sp
GIVES
YOU
sp
SALT
sp
AND
sp
WATER
sp
YEAH
AND
ACID
AND
sp
A
BASE
sp
GOOD
AND
sp
THAT
sp
GAVE
YOU
sp
WHAT
sp
ER
sp
SALT
AND
WATER
sp
RIGHT
sp
AND
sp
ACID
sp
AND
sp
PERHAPS
THE
MOST
sp
AWKWARD
ONE
THE
sp
CARBONATE
WHICH
GAVE
sp
RIGHT
ER
sp
HYDROGEN
sp
THE
sp
CARBONATE
sp
CARBONATE
sp
CARBONATE
OH
sp
YEAH
sp
CARBON
sp
DIOXIDE
DIOXIDE
OKAY
sp
YEAH
CARBON
sp
DIOXIDE
sp
AND
sp
THE
sp
WATER
sp
THAT
sp
WAS
IT
I
WAS
THINKING
sp
I
SAW
THE
H
TWO
YEAH
AND
AND
THE
WATER
YEAH
AND
sp
THE
WATER
AND
sp
THE
AND
SALT
SALT
sp
RIGHT
sp
OKAY
sp
SO
THAT'S
YOUR
sp
TABLE
sp
OF
sp
WHAT
sp
GOES
ON
sp
NOW
sp
YOU
CAN
sp
LOOK
AT
THAT
sp
AND
SORT
sp
OF
CHANT
IT
OUT
sp
TO
YOURSELF
sp
AND
sp
LEARN
THAT
AS
sp
A
TABLE
sp
OR
LEARN
sp
IT
VISUALLY
sp
OR
sp
VAGUELY
REMEMBER
SOME
OF
IT
sp
AND
FILL
IN
THE
GAPS
sp
BY
GOING
BACK
sp
WHAT
HAPPENED
sp
WHEN
sp
WE
TRIED
sp
WHEN
sp
WE
sp
DRIPPED
AC
sp
ACID
ON
sp
A
sp
METAL
sp
YEAH
sp
HYDROGEN
sp
WHAT
HAPPENED
sp
WHEN
sp
WE
sp
DRIPPED
sp
ACID
ON
sp
MARBLE
sp
CHIPPINGS
sp
ON
sp
A
sp
CARBONATE
sp
WHAT
sp
DID
sp
HAPPEN
ER
sp
MARBLE
sp
CHIPPINGS
sp
ON
sp
EFFERVESCES
IT
GIVES
OFF
sp
CARBON
sp
DIOXIDE
CARBON
DIOXIDE
sp
OKAY
sp
WHAT
HAPPENS
sp
WITH
sp
THE
OLD
STANDARDS
sp
THE
sp
ALKALIS
ER
WATER
sp
AND
A
sp
SALT
sp
YEAH
AND
THE
sp
SAME
sp
FOR
THE
sp
BASES
sp
RIGHT
sp
SO
sp
I
RECKON
YOU'VE
GOT
sp
THAT
sp
ALL
SORTED
sp
OUT
sp
YOU
KNOW
THE
SYS
sp
THAT
sp
I
MEAN
THAT'S
sp
THE
SYSTEM
sp
THIS
IS
sp
SAY
THIS
IS
sp
THE
KEY
sp
TO
A
sp
GOOD
sp
GETTING
sp
ON
sp
FOR
EIGHTY
sp
PERCENT
sp
YEAH
OF
sp
THE
CHEMISTRY
sp
YOU
NEED
sp
ERM
sp
YOU'LL
sp
BE
ABLE
sp
TO
LOOK
AT
IT
AND
sp
SAY
sp
WELL
IS
sp
IT
A
sp
IS
IT
AN
ACID
AND
A
sp
BASE
sp
ACID
ALKALI
ACID
sp
METAL
ACID
sp
CARBONATE
sp
IF
IT
IS
sp
EVEN
IF
YOU'VE
sp
NEVER
sp
HEARD
OF
THEM
sp
BEFORE
sp
YOU
KNOW
sp
SORT
OF
sp
FUNNIUM
sp
CARBONATE
OR
sp
SOMETHING
sp
YEAH
sp
YOU'RE
GOING
sp
TO
sp
THINK
sp
WELL
I
KNOW
WHAT
WILL
sp
HAPPEN
sp
WE'LL
GET
sp
IF
sp
YOU
DRIP
HYDROCHLORIC
ACID
sp
ON
IT
sp
YOU'D
GET
sp
FUNNIUM
sp
CHLORIDE
sp
WATER
sp
AND
CARBON
DIOXIDE
YEAH
RIGHT
sp
YOU'D
NEED
TO
KNOW
YEAH
WHAT
sp
THE
VALENCY
sp
IS
sp
TO
MAKE
UP
THIS
sp
FORMULA
sp
YOU
COULD
sp
DO
sp
THE
sp
SAME
IF
sp
IT
sp
WAS
sp
IF
SOMEONE
TOLD
YOU
IT
sp
WAS
AN
sp
SOME
sp
UNKNOWN
sp
SO
IF
sp
IT'S
AN
UNKNOWN
COMPOUND
sp
AND
I
sp
DRIP
sp
LET'S
SAY
IT
WAS
UNKNOWN
COMPOUND
sp
AND
I
sp
DRIPPED
sp
HYDROCHLORIC
ACID
ON
sp
AND
I
sp
GOT
sp
CARBON
DIOXIDE
sp
GIVEN
sp
OFF
sp
YEAH
YEAH
AND
sp
I
sp
GOT
sp
CALCIUM
sp
CHLORIDE
sp
AND
sp
WATER
FORMED
sp
WHAT
sp
WAS
IT
sp
THAT
I
sp
WAS
sp
DRIPPING
sp
ONTO
sp
ER
AND
sp
YOU
GOT
sp
CALCIUM
sp
I
sp
GOT
sp
I
GOT
CARBON
DIOXIDE
sp
GIVEN
sp
OFF
sp
YEAH
sp
SO
IT
sp
MUST
HAVE
sp
BEEN
sp
ERM
A
CARBONATE
sp
IT
MUST
HAVE
BEEN
sp
GOOD
IT
sp
MUST
HAVE
BEEN
SOME
SORT
OF
sp
CARBONATE
sp
AND
THE
SALT
THAT
sp
WAS
sp
FORMED
sp
WAS
FROM
THE
sp
HYDROCHLORIC
ACID
sp
WAS
sp
CALCIUM
sp
CHLORIDE
sp
SO
IT
sp
MUST
HAVE
sp
BEEN
sp
CALCIUM
CARBONATE
sp
SO
sp
I
MEAN
IF
sp
I
sp
I
MIGHT
sp
HAVE
sp
MAGNESIUM
sp
CARBONATE
sp
AND
I
DROP
HYDROCHLORIC
sp
ACID
ON
sp
YEAH
sp
WHAT
sp
WOULD
I
sp
GET
sp
MAGNESIUM
sp
CARBONATE
MAGNESIUM
sp
CARBONATE
sp
DROP
sp
HYDROCHLORIC
sp
ACID
sp
ONTO
sp
THAT
sp
MAGNESIUM
sp
HYDROXIDE
sp
MAGNESIUM
sp
SALT
sp
OF
sp
HYDROCHLORIC
sp
ACID
sp
IT'S
sp
IT'S
ALL
TOO
MUCH
I'M
GETTING
A
BIT
CONFUSED
NOW
IT'S
OKAY
OKAY
OKAY
GO
BACK
sp
SO
sp
WHAT
YOU
NEED
sp
IS
A
WHEN
YOU
GET
WHEN
YOU
GET
I'M
sp
I'M
TRYING
TO
DO
TOO
MUCH
AT
ONCE
sp
NOW
sp
IT'S
sp
OKAY
OKAY
sp
WHEN
YOU
GET
CONFUSED
sp
WHEN
YOU
GET
LOST
sp
YOU'VE
GOT
TO
GO
BACK
AND
sp
FIND
YOUR
DIRECTION
AGAIN
sp
SO
sp
CARBONATES
CARBONATES
YEAH
BUT
IT'S
sp
NOT
IT'S
NOT
OH
I
DON'T
WHAT
DIRECTION
I'M
HEADING
IN
sp
I'M
TRYING
TO
DO
TOO
MANY
sp
THINGS
AT
sp
ONCE
AND
I'M
GETTING
OH
sp
OH
sp
IS
IT
sp
AND
THIS
KIND
OF
sp
THING
IT'S
GETTING
sp
ER
I
JUST
sp
THINK
I'M
GOING
TO
END
UP
sp
MORE
sp
CONFUSED
BY
sp
TRYING
TO
DO
IT
ALL
AT
ONCE
sp
THAN
sp
IF
sp
I
CONCENTRATE
ON
ONE
sp
THING
AT
sp
A
TIME
sp
COS
I'M
GOING
TO
BE
GETTING
sp
IT
MIXED
IN
FUTURE
NOW
OKAY
LET'S
SAY
LET'S
SAY
WE'RE
LOOKING
AT
sp
CARBONATES
sp
YEAH
RIGHT
sp
WE'RE
sp
WE'RE
sp
DRIPPING
THIS
sp
ACID
sp
ON
sp
A
sp
CARBONATE
sp
ERM
AND
YOU
sp
KNOW
sp
YOU'VE
sp
WORKED
OUT
YOU'VE
REMEMBERED
sp
CARBON
DIOXIDE
sp
AND
sp
WATER
sp
AND
A
sp
SALT
sp
BUT
sp
WHAT
ON
EARTH
sp
IS
THE
sp
SALT
sp
WELL
THEY
ALL
GIVE
A
sp
SALT
sp
WHICH
IS
THE
EASIEST
ONE
TO
sp
REMEMBER
sp
FOR
sp
WORKING
OUT
sp
THE
sp
SALT
sp
OUT
sp
OF
THESE
sp
FOUR
sp
HERE
sp
WHICH
IS
sp
THE
sp
EASIEST
sp
ONE
TO
sp
REMEMBER
sp
THE
EASIEST
EQUATION
IF
sp
I
SAID
sp
WRITE
sp
DOWN
THE
EQUATION
sp
FOR
sp
ONE
sp
OF
sp
THESE
WHICH
sp
ONE
sp
WOULD
YOU
GO
sp
FOR
AS
sp
BEING
sp
THE
sp
EASIEST
sp
THE
sp
ONE
YOU'RE
MOST
SURE
sp
ABOUT
sp
ER
ER
sp
THE
ACID
sp
AND
AN
ALKALI
sp
RIGHT
sp
ACID
AND
ALKALI
sp
OKAY
sp
SO
sp
TRY
sp
IT
H
C
L
sp
PLUS
sp
AN
ALKALI
sp
C
A
O
H
sp
IS
THAT
sp
IS
sp
THAT
sp
BALANCED
WHAT'S
C
A
sp
ER
sp
DOUBLE
sp
POSITIVE
sp
C
A
sp
DOUBLE
POSITIVE
sp
OKAY
sp
SO
sp
HOW
MANY
O
HS
sp
WILL
WE
NEED
sp
TO
GO
sp
WITH
sp
THAT
sp
TWO
sp
RIGHT
sp
GOOD
sp
COS
sp
THE
O
H
IS
ONLY
sp
A
SINGLE
NEGATIVE
sp
S
sp
YOU
sp
DON'T
sp
NEED
sp
BRACKETS
AT
sp
THE
sp
END
sp
DO
YOU
sp
S
ERM
sp
I
NEED
sp
IF
I
sp
JUST
sp
PUT
sp
C
A
sp
O
sp
H
sp
TWO
YEAH
IT
sp
WOULD
ONLY
BE
sp
TWO
HS
sp
RIGHT
COS
THEY'RE
sp
SEPARATE
sp
ELEMENTS
sp
LIKE
YEAH
EACH
CAPITAL
sp
LETTER
sp
STARTS
A
sp
NEW
ELEMENT
sp
AND
THAT
WOULD
sp
MEAN
sp
ONE
C
A
sp
ONE
O
AND
sp
TWO
HS
sp
BUT
WHAT
I
sp
IS
sp
ONE
C
A
AND
sp
TWO
sp
O
HS
sp
WHICH
IS
sp
TWO
RIGHT
sp
OS
AND
TWO
HS
sp
YEAH
sp
YEAH
sp
SO
I'VE
GOT
sp
THAT
LOT
sp
AND
WHAT'S
sp
THE
sp
SALT
sp
FORGET
ABOUT
ALL
THE
REST
OF
sp
IT
sp
WE
KNOW
IT
sp
GIVES
sp
WATER
sp
OKAY
sp
CALCIUM
sp
CHLORIDE
sp
RIGHT
NOW
sp
CALCIUM
sp
CARBONATE
sp
C
sp
A
sp
C
sp
O
THREE
IS
sp
THAT
sp
BALANCED
UP
WHAT
sp
DO
WE
NEED
sp
HOW
MANY
sp
DO
WE
NEED
sp
THAT'S
sp
A
sp
DOUBLE
POSITIVE
sp
WHAT
sp
ABOUT
C
sp
O
THREE
ER
sp
WELL
HAVE
A
sp
LOOK
sp
WHERE'S
THE
sp
C
sp
O
sp
THREE
GONE
sp
OKAY
sp
ERM
AND
sp
THAT
IS
sp
A
DOUBLE
sp
NEGATIVE
sp
SO
THAT'S
sp
BALANCED
sp
WELL
sp
YOU
sp
YOU
WROTE
THE
EQUATION
sp
OUT
sp
YOU
WORKED
OUT
WHAT
sp
WAS
HAPPENING
sp
THAT
AND
sp
THE
sp
YOU
NEED
sp
TWO
OF
THOSE
sp
SO
sp
THOSE
TWO
sp
GOT
sp
TOGETHER
sp
AND
THE
SALT
sp
AGAIN
sp
WAS
sp
YEAH
sp
YEAH
sp
YOU'RE
YOU'RE
LOOKING
AT
THE
CARBONATE
sp
TRYING
TO
WORK
OUT
sp
WHAT
sp
ON
sp
EARTH
sp
GOES
ON
sp
HERE
sp
WHAT
IS
sp
THE
sp
SALT
sp
WHEN
sp
YOU
DROP
sp
HYDROCHLORIC
ACID
ONTO
sp
THE
sp
CARBONATE
sp
DON'T
sp
KNOW
sp
BUT
I
CAN
REMEMBER
sp
WHAT
HAPPENS
WITH
THE
ALKALI
sp
AND
THE
ACID
sp
YOU
GET
sp
CALCIUM
sp
CHLORIDE
ER
IT'S
sp
THE
sp
SAME
sp
THE
sp
SALT
sp
IS
sp
THE
SAME
ALL
sp
THE
WAY
THROUGH
sp
HERE
sp
WHETHER
YOU'RE
DROPPING
IT
sp
ON
sp
THE
sp
PUTTING
THE
ACID
TO
sp
THE
sp
THE
{OOV}
THE
sp
THE
METAL
sp
THE
ALKALI
sp
THE
sp
BASE
OR
sp
THE
CARBONATE
sp
THE
SALT
sp
IS
sp
ALWAYS
A
SALT
OF
THE
ACID
sp
SO
sp
HYDROCHLORIC
ACID
sp
ALWAYS
sp
GIVES
sp
YOU
THE
sp
CHLORIDE
sp
SULPHURIC
ACID
sp
ALWAYS
sp
GIVES
sp
YOU
THE
sp
SULPHATE
sp
NITRIC
YEAH
ACID
sp
ALWAYS
GIVES
sp
YOU
THE
NITRATE
sp
YEAH
sp
OKAY
AND
sp
THAT'S
sp
THE
sp
SO
THAT
sp
PATTERN
sp
STRAIGHT
sp
THE
WAY
sp
THROUGH
sp
FOR
ALL
THESE
sp
FOUR
REACTIONS
IT
sp
DOESN'T
MATTER
WHICH
sp
ONE
sp
YOU
DO
sp
SO
THE
sp
SALT
sp
YOU
CAN
sp
REMEMBER
IT
sp
THROUGH
sp
GOING
BACK
sp
TO
sp
THE
ACID
sp
PLUS
ALKALI
sp
REACTION
sp
IT'S
sp
THE
SAME
sp
ONE
sp
YOU
sp
GET
sp
THERE
RIGHT
sp
THE
sp
BASE
sp
ACID
sp
BASE
IT'S
EXACTLY
THE
sp
SAME
sp
THERE'S
NO
DIFFERENCE
sp
YOU'RE
sp
GOING
TO
GET
sp
THE
sp
SAME
sp
SALT
AND
sp
THE
AND
sp
THE
WATER
sp
CARBONATE
sp
IT'S
sp
THE
sp
SAME
AGAIN
sp
JUST
sp
CHUCK
sp
IN
sp
THE
EXTRA
sp
C
sp
O
sp
TWO
sp
RIGHT
sp
AND
PERHAPS
THE
MOST
DIFFICULT
ONE
sp
TO
REMEMBER
IS
sp
THE
sp
EASIEST
sp
OF
THE
LOT
sp
THE
ACID
sp
PLUS
sp
THE
METAL
sp
COS
THERE'S
sp
NONE
OF
THE
USUAL
sp
STUFF
sp
NO
SALT
sp
NO
WATER
sp
JUST
THE
HYDROGEN
sp
COMING
OFF
YEAH
sp
BUT
sp
IT'S
sp
YOU
CAN
sp
I
KNOW
YOU
THINK
IT'S
A
LOT
TO
sp
TAKE
sp
IN
sp
YEAH
sp
BUT
sp
IF
sp
ONCE
YOU
CAN
sp
SEE
IT
AS
A
sp
PATTERN
sp
ALL
THIS
LOT
FIT
sp
TOGETHER
sp
AND
sp
YOU'RE
NOT
sp
IF
YOU
LEARN
THOSE
sp
FOUR
REACTIONS
sp
SEPARATELY
A
sp
MONTH
sp
APART
OR
sp
SOMETHING
sp
YEAH
sp
YOU'RE
LEARNING
THE
SAME
INFORMATION
sp
OVER
sp
AND
OVER
sp
AGAIN
sp
THIS
sp
LOT
sp
YOU'RE
LEARNING
sp
THE
sp
WHOLE
sp
LOT
sp
ONCE
sp
IT'S
sp
IT'S
AS
sp
THOUGH
sp
EVERY
TIME
YOU
LEARNED
A
WORD
YOU
HAD
sp
TO
sp
LEARN
YOUR
ALPHABET
sp
ALL
OVER
sp
AGAIN
RIGHT
sp
AND
sp
DIDN'T
REALIZE
sp
THAT
sp
THE
A
MADE
THE
SAME
SOUND
IN
sp
THIS
sp
WORD
AS
sp
IT
DOES
IN
THAT
sp
I
KNOW
IT
DOESN'T
IN
sp
MOST
sp
BUT
sp
BUT
THERE
IS
ENOUGH
sp
OF
A
A
sp
TIE
UP
sp
MM
sp
TO
sp
MAKE
IT
EASIER
TO
sp
LEARN
THAT
sp
WAY
NOW
DO
sp
YOU
STILL
sp
FEEL
THAT
IT
IS
sp
TOO
MUCH
FOR
sp
YOU
TO
sp
TAKE
sp
ALL
THAT
sp
LOT
IN
sp
IN
sp
ONE
GO
sp
OR
DO
YOU
sp
THINK
IT'S
ALL
sp
IT'S
IT'S
IT'S
GU
IT'S
sp
A
LITTLE
BIT
YEAH
sp
YOU
KNOW
sp
YEAH
GELLING
TOGETHER
A
sp
BIT
sp
NO
I
sp
THINK
sp
WHAT
IT
IS
sp
I
UNDERSTAND
IT
NOW
BUT
IF
YOU
ASK
ME
IN
A
COUPLE
sp
OF
WEEKS
sp
RIGHT
I'M
NOT
GOING
TO
BE
SURE
{OOV}
sp
WHETHER
AN
ACID
AND
A
CARBONATE
WELL
I'LL
ASK
YOU
EVERY
WEEK
I
MIGHT
SAY
YEAH
I'LL
ASK
YOU
EVERY
WEEK
sp
CAN
I
JUST
SAY
SOMETHING
BUT
sp
I
MIGHT
sp
GET
AN
ACID
AND
A
CARBONATE
MIXED
UP
sp
WITH
AN
ACID
AND
A
METAL
sp
OR
OKAY
sp
AN
ACID
AND
A
METAL
WITH
AN
ACID
AND
A
CARBONATE
BUT
sp
BUT
sp
BUT
IF
YOU
WRITE
sp
THE
sp
FORMULA
DOWN
sp
LET'S
sp
SAY
sp
LET'S
SAY
YOU
GET
IT
sp
ALL
WRONG
sp
AND
I
SAY
sp
WHAT
HAPPENS
sp
IF
YOU
HAVE
AN
ACID
sp
AND
AN
ALKALI
sp
AND
YOU
SAY
sp
WELL
sp
I
KNOW
THEY
ALL
GIVE
A
SALT
sp
SO
THAT'S
A
SAFE
sp
BET
sp
SO
I'LL
SAY
THEY
GIVE
sp
A
sp
SALT
ERM
sp
THEY
sp
ALL
GIVE
A
WATER
sp
APART
sp
FROM
THE
ONE
THAT'S
JUST
sp
WITH
THE
METAL
sp
RIGHT
sp
SO
sp
WATER'S
sp
A
sp
GOOD
sp
BET
sp
AND
sp
I
sp
THINK
THIS
GIVES
CARBON
DIOXIDE
sp
LET'S
sp
SAY
sp
YOU'RE
DOING
ACID
sp
PLUS
ALKALI
AND
sp
FOR
SOME
sp
REASON
sp
YOU
THINK
OH
WELL
I
sp
THINK
IT
GIVES
CARBON
sp
DIOXIDE
sp
SO
I
SAY
OKAY
sp
WHERE
DOES
YOUR
CARBON
DIOXIDE
COME
sp
FROM
sp
THEN
sp
ACID
sp
H
sp
C
L
AND
sp
THE
STANDARD
ALKALI
sp
ACID
ALKALI
sp
REACTION
WE
sp
USE
sp
WHAT
sp
DO
WE
NORMALLY
sp
PICK
sp
FOR
THE
ALKALI
sp
WHAT'S
sp
ER
THE
WELL
KNOWN
sp
ONE
sp
WE
sp
KEEP
sp
CHOOSING
sp
ER
SODIUM
sp
HYDROXIDE
sp
RIGHT
sp
ALL
THE
ALKALIS
sp
THAT
sp
WE'RE
USING
ANYWAY
sp
ALL
sp
THE
HYDROXIDES
sp
ARE
ALKALINE
sp
SO
sp
WHAT'S
GOING
TO
HAPPEN
sp
THERE
THEY
GO
sp
TOGETHER
THE
sp
CHLORINE
sp
AND
SODIUM
sp
GO
sp
TOGETHER
sp
TO
sp
MAKE
sp
THE
SODIUM
sp
CHLORIDE
sp
AND
THE
H
AND
THE
O
H
sp
GO
TOGETHER
AND
sp
MAKE
sp
THE
WATER
sp
YOU'VE
GOT
sp
NO
CHANCE
OF
MAKING
sp
C
O
sp
THREE
OUT
OF
THAT
sp
YOU
HAVEN'T
GOT
sp
THE
sp
C
ANYWHERE
YEAH
sp
SO
IF
YOU
WANT
TO
MAKE
sp
SORRY
sp
C
O
sp
TWO
IF
YOU
WANT
TO
MAKE
C
O
sp
TWO
OUT
OF
sp
SOMETHING
sp
YOU'RE
GOING
TO
AT
LEAST
sp
HAVE
TO
HAVE
A
C
IN
IT
sp
SOMEWHERE
sp
RIGHT
sp
YEAH
AND
WHICH
ONE
OF
THIS
sp
LOT
sp
HAS
sp
GOT
sp
THE
C
IN
sp
IS
IT
sp
THE
METAL
THE
ALKALI
THE
BASE
sp
OR
sp
THE
CARBONATE
sp
CARBONATE
sp
CARBONATE
sp
NOT
ONLY
HAS
IT
GOT
sp
THE
C
sp
IT'S
sp
GOT
THE
C
O
sp
THREE
sp
TAKE
THE
O
OUT
OF
IT
sp
TO
GO
WITH
sp
THE
H
sp
AND
sp
WE'VE
GOT
sp
THAT
sp
C
O
sp
TWO
OUT
sp
SO
sp
IT'S
A
COMBINATION
OF
sp
SORT
OF
WORKING
AT
OF
sp
WORKING
AND
sp
THAT
YEAH
TO
sp
GIVE
THE
WATER
STICK
sp
TO
sp
THE
NICE
sp
SIMPLE
ONES
sp
LIKE
H
sp
C
sp
L
sp
YEAH
sp
WHAT'S
sp
GOING
sp
TO
sp
HAPPEN
sp
N
A
sp
PLUS
sp
H
sp
C
sp
L
sp
A
sp
STRAIGHT
sp
FORWARD
sp
METAL
sp
PLUS
sp
AN
sp
ACID
WHAT
sp
HAPPENS
sp
HERE
sp
N
A
sp
PLUS
sp
H
C
L
sp
RIGHT
sp
THAT'S
A
METAL
sp
A
ME
A
sp
METAL
sp
PLUS
sp
AN
ACID
ERM
sp
GIVES
OFF
sp
HYDROGEN
sp
RIGHT
EVERYONE
OF
THESE
sp
THE
BIG
sp
THE
ONE
sp
THING
THEY'VE
ALL
GOT
sp
IS
A
sp
SALT
sp
SO
sp
WHAT'S
sp
THE
sp
SALT
FROM
sp
THERE
sp
ER
sp
THE
sp
N
sp
A
C
sp
L
sp
N
A
sp
C
L
sp
AND
WHAT
HAVE
YOU
GOT
sp
LEFT
sp
OVER
ER
sp
HYDROGEN
H
sp
THAT'S
sp
IT
sp
SO
WE
sp
TAKE
TWICE
sp
WE
TAKE
TWO
OF
IT
sp
SO
THAT
sp
WE
GET
sp
H
TWO
sp
YEAH
sp
SO
sp
WITH
THIS
sp
SYSTEM
sp
YOU'LL
REMEMBER
sp
BITS
sp
YOU'LL
sp
FORGET
sp
BITS
sp
THE
BITS
YOU
DON'T
REMEMBER
sp
YOU
CAN
NOW
WORK
sp
THEM
OUT
sp
FROM
THE
sp
PATTERNS
sp
AND
EACH
TIME
YOU
WORK
IT
sp
OUT
sp
IT'S
sp
MORE
sp
IT
IT
sp
BECOMES
sp
MORE
ER
sp
ONE
sp
YOU
REMEMBER
RATHER
sp
THAN
ONE
sp
YOU
HAVE
sp
TO
sp
WORK
sp
OUT
sp
TILL
EVENTUALLY
I
sp
MEAN
YOU
ERE
DOING
IT
WITH
THESE
AS
YOU
WERE
GOING
sp
THROUGH
HERE
YOU
WEREN'T
LOOKING
AT
THIS
sp
TABLE
sp
YOU
WERE
WORKING
SOME
sp
OF
THEM
OUT
sp
YOU
WERE
SAYING
sp
OH
THAT'LL
BE
A
DOUBLE
sp
POSITIVE
sp
THAT'LL
BE
A
sp
DOUBLE
DOUBLE
NEGATIVE
sp
THESE
LL
sp
GO
sp
TOGETHER
sp
THE
sp
MORE
YOU
USE
IT
sp
THE
MORE
sp
THE
SYSTEM
sp
BECOMES
sp
NATURAL
sp
TO
sp
YOU
sp
YEAH
sp
AND
sp
YOU
THINK
WELL
OF
COURSE
IT
WOULD
sp
WOULDN'T
IT
sp
YOU
KNOW
sp
YOU'RE
TRYING
sp
TO
sp
YOU
GET
TO
THE
STAGE
YOU
sp
CAN
BELIEVE
sp
ME
sp
YOU
GET
sp
TO
THE
STAGE
sp
QUITE
sp
QUICKLY
sp
WHERE
YOU
CAN'T
UNDERSTAND
sp
WHY
OTHER
PEOPLE
sp
DON'T
sp
SEE
sp
IT
LOOK
IT'S
OBVIOUS
sp
THIS
ONE'S
A
sp
DOUBLE
sp
POSITIVE
AND
THAT'S
A
DOUBLE
NEGATIVE
SO
THEY'RE
GOING
TO
GO
sp
TOGETHER
sp
AND
YOU'RE
LEFT
sp
WITH
sp
H
sp
AND
O
H
sp
WHICH
IS
GOING
TO
MAKE
sp
THE
WATER
sp
IT'S
OBVIOUS
ISN'T
IT
sp
YEAH
sp
OKAY
sp
SO
TRY
sp
IF
YOU
CAN
sp
CAN
DO
sp
YOU
THINK
YOU
CAN
DO
THAT
YOU
CAN
TRY
TO
TAKE
sp
THOSE
sp
FOUR
sp
REACTIONS
OUT
OF
sp
ONE
sp
GROUP
sp
AND
SEE
HOW
sp
RELATED
sp
THEY
ARE
sp
YEAH
sp
WHAT'S
sp
WHAT'S
sp
THE
BIG
THING
THAT'S
sp
COMMON
sp
TO
sp
ALL
OF
sp
THEM
sp
ERM
THEY
ALL
sp
MAKE
sp
A
SALT
sp
RIGHT
sp
THEY
ALL
MAKE
sp
THE
SALT
sp
THEY
ALL
MAKE
IT
IN
sp
THE
sp
SAME
sp
WAY
sp
HYDROCHLORIC
ACID
WOULD
sp
MAKE
ER
sp
WATER
AND
sp
A
sp
SALT
sp
HYDROCHLORIC
sp
YEAH
sp
HYDROCHLORIC
ACID
WHAT
SORT
OF
A
SALT
sp
WOULD
sp
IT
MAKE
ER
ER
sp
WELL
sp
MIXED
WITH
sp
WHAT
ALKALI
WELL
SAY
IF
IT'S
sp
MIXED
sp
WITH
ERM
sp
SODIUM
sp
HYDROXIDE
sp
ER
sp
SU
sp
ER
sp
SULPHUR
SULPHUR
sp
HYDROXIDE
HYDROCHLORIC
sp
HYDROCHLORIC
sp
ACID
sp
HYDROCHLORIC
ER
sp
HYDROCHLORIC
sp
ACID
sp
OKAY
sp
I'M
sp
THINKING
ABOUT
sp
TOO
MUCH
I
JUST
CAN'T
I'M
GETTING
TOTALLY
CONFUSED
NOW
YEAH
I
KN
RIGHT
RIGHT
LOOK
AT
THE
PICTURES
THEN
sp
DON'T
OKAY
sp
STOP
THINKING
OF
HYDROCHLORIC
ACID
sp
THINK
OF
H
C
L
sp
H
C
L
YEAH
BUT
IT'S
STILL
MAKING
ME
sp
CONFUSED
I'M
THINKING
ABOUT
TOO
sp
MUCH
AT
ONCE
IT'S
MAKING
sp
IT
WORSE
sp
OKAY
HOW
sp
HOW
CAN
WE
SIMPLIFY
sp
IT
ERM
TO
sp
WORK
sp
OUT
sp
I
THINK
I
THINK
I'M
sp
TRYING
TO
DO
TOO
MUCH
AT
ONCE
I'M
GOING
TO
BE
sp
REALLY
CONFUSED
NEXT
sp
WEEK
sp
YOU'VE
DECIDED
sp
NO
I'VE
NOT
DECIDED
BUT
I
KNOW
I
AM
I'VE
sp
DONE
sp
THIS
THING
sp
BEFORE
IT'S
sp
RIGHT
sp
HOW
MUCH
SHOULD
WE
TAKE
OUT
OF
THIS
sp
JUST
sp
TO
LEARN
AND
sp
CONCENTRATE
ON
sp
FOR
sp
ALL
sp
OF
sp
NEXT
sp
WEEK
sp
IT'S
NOT
THAT
YOU'RE
ASKING
ME
sp
OH
sp
WELL
WHAT
HAPPENS
IF
YOU
sp
AND
I
sp
I'VE
THOUGHT
ABOUT
IT
AND
I'VE
THOUGHT
ABOUT
SO
MANY
OF
sp
THEM
TODAY
I
sp
CAN'T
sp
I'M
GETTING
CONFUSED
AT
WHICH
ONE
sp
IT
IS
sp
BECAUSE
YOU'VE
ASKED
ME
ABOUT
SO
sp
MANY
OF
sp
THEM
RIGHT
sp
WELL
WE'RE
ONLY
sp
WE'RE
LOOKING
sp
AT
FOUR
sp
DIFFERENT
sp
TYPES
SO
IF
sp
I
ASK
YOU
WHICH
ONE
sp
YEAH
I
KNOW
IT'S
ONLY
sp
FOUR
DIFFERENT
TYPES
OF
RIGHT
OF
THESE
YOU
THINK
sp
NOW
BUT
YOU'RE
USING
SO
sp
MANY
DIFFERENT
CHEMICALS
sp
THAT
IT'S
sp
GETTING
sp
MORE
AND
MORE
CONFUSING
ALRIGHT
sp
SO
WE'LL
STICK
TO
sp
ONE
ACID
sp
H
sp
YEAH
H
C
L
YEAH
BUT
IF
YOU
JUST
SAID
AN
ACID
sp
AND
sp
A
SO
AND
SO
sp
BUT
YOU'RE
SAYING
sp
A
sp
H
C
L
AND
A
sp
AND
IT'S
sp
I
KNOW
OKAY
I
KNOW
IT'S
STILL
AN
ACID
sp
BUT
THE
WAY
IT'S
THINKING
ABOUT
IT'S
MAKING
ME
CONFUSED
OKAY
OKAY
RIGHT
sp
SO
sp
AN
ACID
AND
AN
ALKALI
WHAT
DO
WE
sp
GET
ERM
sp
A
sp
WATER
A
sp
SALT
sp
RIGHT
sp
NOW
sp
IF
THE
ACID
HAPPENS
sp
TO
BE
sp
HYDROCHLORIC
sp
ACID
sp
WITH
sp
THE
sp
C
L
ON
sp
THE
END
sp
WHEN
IT
MAKES
sp
THE
sp
SALT
HAVE
sp
A
LOOK
AT
THAT
sp
ONE
YEAH
sp
WHAT'S
sp
THE
SALT
sp
GOING
TO
sp
BE
sp
THERE
sp
ER
sp
{OOV}
A
sp
C
L
AND
N
sp
A
sp
THAT'S
IT
sp
SO
IT'S
sp
N
A
sp
C
L
sp
THE
SALTS
OF
sp
H
C
L
sp
ARE
sp
SOMETHING
sp
C
L
sp
YEAH
sp
HYDROCHLORIC
ACID
sp
MAKES
sp
THE
CHLORIDES
sp
YEAH
YEAH
sp
MM
sp
IF
sp
WE'D
HAVE
USED
sp
IF
sp
WE'D
sp
SO
THAT
WAS
sp
HYDROGEN
sp
CHLORIDE
sp
MAKES
sp
THE
CHLORIDES
sp
HYDROGEN
sp
SULPHATE
sp
H
TWO
S
sp
O
FOUR
sp
GIVES
YOU
sp
THE
SULPHATES
THE
sp
ONES
sp
THAT
END
sp
IN
AND
WHAT
sp
DOES
sp
HYDROGEN
sp
NITRATE
sp
NITRIC
ACID
sp
WHAT
sp
DOES
THAT
sp
ONE
GIVE
YOU
sp
ER
sp
H
N
O
sp
THREE
sp
NI
sp
SO
sp
THIS
sp
THIS
sp
LET'S
SAY
sp
WE'RE
USING
N
H
SODIUM
NITRATE
IS
IT
sp
YEAH
sp
IT'S
SODIUM
NITRATE
sp
SO
sp
NITRIC
ACID
sp
BECAUSE
IT'S
sp
HYDROGEN
sp
NITRATE
sp
GIVES
YOU
sp
THE
NITRATES
sp
SULPHURIC
ACID
GIVES
sp
YOU
sp
THE
sp
SULPHATES
sp
YEAH
sp
HYDROGEN
sp
CHLORINE
sp
{OOV}
sp
CHLORIDE
sp
H
sp
C
L
sp
GIVES
YOU
THE
sp
CHLORIDES
MM
ERM
sp
WE'LL
DO
sp
I'LL
JUST
sp
GET
YOU
TO
sp
WRITE
THAT
OUT
IN
sp
WORDS
AND
sp
THEN
WE'LL
HAVE
A
BREAK
sp
YEAH
AND
A
A
sp
LITTLE
sp
STROLL
AROUND
THE
ROOM
OR
SOMETHING
YEAH
sp
BECAUSE
IT'S
sp
COMING
sp
UP
sp
TO
sp
TIME
sp
NOW
sp
ANYWAY
sp
SO
sp
WE
sp
MIGHT
AS
sp
WELL
sp
FORGET
sp
THE
sp
BREAK
sp
OKAY
sp
WHAT
sp
TIME
sp
DID
I
sp
GET
HERE
THEN
sp
QUARTER
PAST
YEAH
sp
OKAY
sp
THEN
sp
SO
HYDROCHLORIC
ACID
sp
HYDROGEN
sp
CHLORIDE
sp
YEAH
sp
RIGHT
sp
PLUS
sp
SODIUM
sp
HYDROXIDE
sp
NOW
sp
WHAT
sp
ALL
THAT
HAPPENS
sp
IS
THAT
sp
THESE
TWO
sp
CHANGE
sp
PLACES
sp
YEAH
sp
SO
sp
WE
THEN
GET
sp
SODIUM
sp
CHLORIDE
sp
AND
sp
HYDROGEN
sp
HYDROXIDE
sp
YEAH
sp
HYDROGEN
sp
HYDROXIDE
sp
H
sp
O
sp
H
sp
WELL
sp
WE
USUALLY
sp
WRITE
sp
THAT
sp
H
sp
TWO
sp
O
MM
sp
SO
sp
IF
YOU
THINK
OF
THE
SORT
OF
sp
THE
WORD
PATTERNS
sp
HYDROGEN
sp
CHLORIDE
sp
SODIUM
sp
HYDROXIDE
sp
GIVES
YOU
sp
SODIUM
sp
CHLORIDE
sp
AND
HYDROGEN
sp
HYDROXIDE
sp
YEAH
sp
MM
sp
YEAH
IT'S
sp
PERHAPS
sp
PERHAPS
EASIER
sp
TO
SEE
IT
sp
AS
sp
THE
sp
AS
THE
N
AS
AND
sp
THE
O
sp
HS
sp
THOUGH
OKAY
OR
IF
sp
WE
DID
IT
sp
WITH
sp
SULPHURIC
sp
ACID
sp
WE'D
sp
HAVE
sp
HYDROGEN
sp
SULPHATE
sp
PLUS
sp
SODIUM
sp
HYDROXIDE
sp
WHAT'S
sp
THAT
GOING
sp
TO
GIVE
US
sp
AGAIN
sp
THEY
JUST
sp
CHANGE
sp
ROUND
sp
THEY
SWAP
sp
PLACES
sp
MM
sp
TO
GIVE
sp
US
sp
SODIUM
sp
SULPHATE
sp
AND
sp
HYDROGEN
sp
HYDROXIDE
AGAIN
YEAH
sp
WATER
sp
H
O
sp
H
sp
WATER
NITRIC
sp
ACID
sp
HYDROGEN
sp
NITRATE
sp
PLUS
sp
SODIUM
sp
CHLORIDE
sp
AGAIN
sp
THESE
sp
TWO
sp
SWAP
sp
PLACES
AND
sp
WE
GET
sp
THE
SODIUM
sp
NITRATE
sp
AND
sp
HYDROGEN
sp
HYDROXIDE
AGAIN
sp
YEAH
sp
H
O
sp
H
sp
WATER
sp
THAT'S
sp
THE
sp
THAT'S
sp
THE
sp
PATTERN
sp
THAT
sp
ALL
THE
ACIDS
sp
ARE
sp
FOLLOWING
sp
WRITE
sp
THEIR
NAMES
sp
WRITE
sp
WRITE
IT
LIKE
sp
THIS
sp
H
C
L
sp
N
sp
A
O
H
sp
YEAH
sp
SWAP
sp
THEM
sp
ROUND
sp
AND
THERE'S
THE
ANSWER
sp
RIGHT
sp
THAT'S
sp
DONE
IT
sp
HYDROGEN
SULPHATE
sp
SODIUM
HYDROXIDE
sp
SWAP
THEM
sp
ROUND
sp
SODIUM
sp
SULPHATE
sp
HYDROGEN
sp
HYDROXIDE
sp
HY
sp
WE
NEVER
SAY
sp
HYDROGEN
sp
HYDROXIDE
sp
IT'S
SIMPLER
TO
sp
SAY
sp
WATER
sp
BUT
IF
sp
YOU
WRITE
IT
sp
AS
sp
H
sp
O
sp
H
sp
THEN
YOU
sp
THINK
AH
sp
WE'VE
sp
GOT
THE
TWO
HS
AND
THE
O
sp
THERE
sp
WATER
sp
MM
sp
AND
sp
THAT'S
sp
THAT'S
IT
sp
THAT'S
THE
sp
PATTERN
sp
FOR
ALL
OF
THEM
sp
FOR
ALL
THOSE
sp
FOUR
sp
REACTIONS
sp
SO
sp
THAT'LL
sp
RIGHT
sp
THE
sp
SALT
ERM
sp
HAVE
YOU
GOT
ANY
OF
YOUR
BOOKS
sp
WITH
sp
YOU
YEAH
sp
ERM
sp
HAVE
sp
YOU
GOT
sp
YOUR
sp
CHEMISTRY
COURSE
sp
BOOK
THAT
sp
YOU'RE
sp
WORKING
FROM
WE'RE
WE'RE
NOT
REALLY
sp
WORKING
sp
FROM
IT
sp
WE'RE
MM
sp
IT'S
JUST
A
BOOK
sp
WE
sp
HAVE
sp
OKAY
sp
THE
WELL
sp
IF
sp
YOU
CAN
GET
sp
THAT
sp
WE'LL
HAVE
A
LOOK
sp
AT
sp
THAT
sp
AND
I
WANT
YOU
TO
sp
TRY
sp
SOME
OF
sp
THESE
sp
EQUATIONS
sp
IN
IT
sp
AND
I
WANT
YOU
TO
sp
TRY
THEM
IN
sp
GROUPS
sp
SO

THAT
sp
ACID
ALKALI
sp
YEAH
sp
I
THINK
I
RECKON
YOU
COULD
sp
YOU
COULD
JUST
sp
DO
THAT
sp
WITHOUT
sp
LOOKING
AT
YOUR
sp
BOOK
sp
COULDN'T
YOU
sp
YEAH
sp
YEAH
sp
YEAH
IF
SOMEONE
SAID
sp
OKAY
sp
NITRIC
ACID
AND
sp
CALCIUM
sp
HYDROXIDE
sp
AS
sp
LONG
AS
YOU
WERE
USING
THIS
sp
CHART
sp
TO
sp
WORK
sp
OUT
sp
WHICH
sp
ARE
sp
SINGLE
sp
NEGATIVE
sp
AND
sp
DOUBLE
sp
NEGATIVE
sp
WHAT'S
GOING
TO
HAPPEN
sp
TO
sp
THAT
sp
ONE
YOU'VE
sp
GOT
NITRIC
ACID
sp
YEAH
sp
HYDROGEN
sp
NITRATE
sp
PLUS
sp
CALCIUM
sp
HYDROXIDE
sp
YEAH
sp
IS
GOING
sp
TO
sp
GIVE
sp
YOU
sp
WELL
sp
THESE
TWO
sp
THE
METAL
AND
sp
THE
sp
HYDROGEN
sp
JUST
sp
SWAP
sp
ROUND
sp
EACH
sp
TIME
sp
SO
IT'S
sp
GOING
sp
TO
sp
GIVE
sp
YOU
sp
CALCIUM
sp
NITRATE
sp
AND
sp
THE
OLD
sp
HYDROGEN
sp
HYDROXIDE
sp
AGAIN
sp
YOU
sp
YOU
CAN
YOU
CAN
LOOK
AT
I
sp
MEAN
sp
IT'S
EASIER
WITH
YOUR
sp
FORMULA
IF
sp
YOU'VE
sp
GOT
sp
H
sp
N
sp
O
THREE
AND
sp
C
A
sp
O
sp
H
sp
TWICE
sp
C
A
sp
AND
THAT'S
sp
GOING
sp
TOGETHER
sp
YOU'LL
NEED
TWO
OF
THESE
sp
BECAUSE
sp
WE
WANT
sp
TWO
sp
O
HS
sp
TO
sp
GO
WITH
sp
THOSE
sp
TWO
sp
O
sp
HS
YEAH
sp
AND
YOU'LL
WANT
sp
TWO
sp
N
O
sp
THREE'S
sp
TO
sp
GO
sp
WITH
sp
THAT
sp
C
A
SO
sp
ANY
OF
sp
THESE
sp
I
RECKON
sp
YOU
COULD
WORK
OUT
sp
ANY
sp
ANY
ACID
sp
WITH
sp
ANY
ALKALI
sp
YOU
COULD
sp
WORK
sp
IT
sp
OUT
sp
YEAH
sp
SO
HAVE
A
LOOK
sp
THROUGH
YOUR
BOOK
sp
HAVE
A
sp
VERY
QUICK
sp
GLANCE
sp
AT
sp
ERM
sp
IF
YOU
CAN
JUST
AT
AN
ACID
sp
ALKALI
ONE
sp
AT
sp
ONE
SIDE
sp
OF
sp
AN
EQUATION
sp
CO
sp
TRY
NOT
TO
READ
IT
sp
COVER
IT
UP
sp
WRITE
IT
sp
DOWN
sp
AND
LEAVE
IT
FOR
A
FEW
MINUTES
sp
TILL
sp
YOU'VE
sp
FORGOTTEN
sp
IF
YOU
DID
ACCIDENTALLY
sp
SEE
WHAT
sp
WAS
sp
ON
THE
sp
OTHER
sp
SIDE
sp
TILL
YOU'VE
sp
FORGOTTEN
sp
IT
sp
ERM
RIGHT
sp
WRITE
A
FEW
OF
THOSE
sp
DOWN
sp
ALL
THE
SAME
TYPE
sp
ALL
sp
ACIDS
AND
ALKALI
sp
AND
THEN
sp
YOU
JUST
sp
YOU
CAN
JUST
sp
BOMB
sp
THROUGH
THOSE
sp
THEN
sp
TRY
SOME
sp
WITH
sp
BASES
sp
YEAH
TRY
A
sp
FEW
sp
OF
THOSE
sp
ERM
sp
THAT
ONE
sp
REALLY
YEAH
YOU
sp
COULD
sp
WORK
OUT
sp
ANY
ONE
sp
OF
THOSE
sp
AT
ALL
sp
ANY
METAL
sp
WITH
ANY
ACID
sp
BECAUSE
THE
METAL
JUST
COMES
IN
sp
PUSHES
sp
THE
HYDROGEN
sp
OUT
sp
SO
IF
IT
sp
WAS
sp
HYDROGEN
SULPHATE
SULPHURIC
ACID
sp
IT'LL
sp
PUSH
THE
sp
HYDROGEN
OUT
AND
sp
BECOME
sp
ZINC
SULPHATE
sp
AND
LIBERATE
sp
THE
sp
HYDROGEN
sp
IF
IT
WAS
HYDROGEN
sp
NITRATE
sp
THE
NITRIC
ACID
sp
THE
ZINC
sp
WOULD
sp
PUSH
sp
THE
sp
HYDROGEN
sp
OUT
sp
AND
MAKE
A
ZINC
sp
NITRATE
sp
ERM
THE
CARBONATE
sp
PERHAPS
THE
sp
MOST
AWKWARD
sp
ONE
sp
YEAH
sp
BUT
sp
YOU'VE
sp
WORKED
sp
THAT
sp
OUT
sp
YOURSELF
I
LIKE
sp
THAT
BECAUSE
YOU
sp
YOU
WENT
FOR
THE
SALT
sp
SEE
YOU
KNEW
sp
YOU
WERE
sp
DOING
sp
EXACTLY
sp
WHAT
I
WAS
SAYING
sp
SORT
OF
sp
FORMING
THE
sp
PATTERN
sp
YEAH
sp
BUT
YOU
sp
YOU
DON'T
sp
WANT
TO
YOU
DON'T
WANT
TO
sp
SEE
THAT
YOU'RE
DOING
IT
THAT
sp
WAY
sp
YEAH
sp
SO
WENT
STRAIGHT
FOR
THE
CALCIUM
sp
CHLORIDE
sp
THIS
sp
IS
sp
THE
sp
PAGE
sp
WHERE
YOU
sp
DID
IT
sp
RIGHT
sp
QUITE
AN
AWKWARD
sp
ONE
sp
THAT
I
GAVE
sp
YOU
sp
HYDROGEN
sp
CHLORIDE
sp
CALCIUM
sp
CARBONATE
sp
YOU
sp
PUT
YOUR
sp
YOUR
sp
DOUBLE
AND
sp
SINGLE
sp
NEGATIVES
ON
sp
WELL
sp
WE'RE
GOING
TO
GET
sp
A
SALT
sp
COS
THEY
ALL
GIVE
SALTS
sp
THERE'S
YOUR
CALCIUM
sp
CHLORIDE
sp
WHAT
HAVE
WE
GET
sp
LEFT
OVER
sp
WE'VE
GOT
sp
THIS
sp
WE'VE
GOT
sp
HYDROGEN
sp
CARBONATE
sp
AND
THAT
WAS
sp
REALLY
sp
SHOULD
HAVE
sp
BEEN
sp
YOUR
ANSWER
BUT
sp
THEN
sp
YOU
KNOW
sp
CARBON
DIOXIDE
CAME
OUT
sp
SO
YOU
JUST
sp
TOOK
sp
IT
sp
OUT
AND
sp
YOU
GOT
sp
WATER
LEFT
OVER
sp
YEAH
sp
SO
sp
THAT
GIVES
YOU
THIS
sp
FITS
WITH
sp
THIS
sp
PATTERN
ACID
sp
CARBONATE
sp
THEY
ALL
GIVE
sp
A
SALT
sp
APART
FROM
sp
THE
sp
HYDROGEN
sp
ONE
sp
THEY
ALL
sp
GIVE
sp
WATER
AS
WELL
AND
sp
THIS
sp
ONE
sp
GIVES
A
C
sp
O
TWO
YEAH
sp
RIGHT
sp
SO
sp
I
sp
DO
sp
WANT
YOU
TO
sp
TRY
sp
TO
sp
BUILD
UP
sp
AS
sp
MANY
OF
THOSE
AS
YOU
sp
CAN
THINK
sp
I
THINK
THE
ACID
ALKALI
sp
THERE'S
NO
PROBLEM
OH
sp
YEAH
I
KNOW
BUT
sp
ALL
I
WAS
SAYING
WAS
THAT
sp
MUCH
OF
sp
DIFFERENT
THINGS
RIGHT
IN
ONE
sp
LESSON
sp
WITHIN
A
SPACE
OF
sp
FIFTEEN
MINUTES
sp
RIGHT
THAT
sp
IN
ONE
OR
sp
TWO
WEEKS
TIME
sp
I'M
GOING
TO
sp
BE
sp
THIN
sp
I'M
GOING
TO
BE
SLIGHTLY
MIXED
UP
sp
RIGHT
sp
WELL
sp
LEARN
THEM
sp
THIS
sp
WAY
sp
THEN
LEARN
sp
ONLY
sp
THE
SODIUM
sp
HYDROXIDE
sp
RIGHT
sp
YEAH
sp
AND
sp
ERM
sp
OH
sp
CALCIUM
sp
HYDROXIDE
sp
IS
sp
PERHAPS
A
sp
MORE
sp
INTERESTING
sp
ONE
sp
BUT
YOU
PICK
sp
ONE
OF
THEM
sp
THAT
sp
YOU'RE
sp
HAPPY
sp
WITH
sp
AND
sp
TAKE
IT
sp
THROUGH
sp
HERE
sp
SO
sp
WHAT
WOULD
sp
HAPPEN
sp
WITH
sp
LET'S
sp
SEE
I
sp
MEAN
sp
YOU
WOULDN'T
ACTUALLY
DRIP
sp
SODIUM
sp
AN
ACID
ONTO
SODIUM
sp
IF
YOU'VE
sp
GOT
ANY
SENSE
sp
OKAY
YEAH
I
KNOW
sp
BOOM
sp
BUT
YOU
SHOULD
GET
ROUGHLY
THE
SAME
sp
REACTION
ERM
sp
SO
sp
MAYBE
WE
sp
COULD
sp
WE'VE
BEEN
USING
SODIUM
A
LOT
sp
TRY
CALCIUM
sp
BECAUSE
IT'S
INTERESTING
sp
COS
IT'S
sp
GOT
A
DOUBLE
ONE
A
DOUBLE
sp
POSITIVE
sp
NEGATIVE
IS
sp
IT
sp
MM
sp
RIGHT
sp
SO
sp
TAKE
sp
THEM
THROUGH
THERE
sp
ACID
sp
PLUS
sp
CALCIUM
sp
ACID
sp
PLUS
sp
ALKALI
sp
CALCIUM
sp
HYDROXIDE
sp
ACID
sp
PLUS
sp
BASE
sp
CALCIUM
OXIDE
SO
sp
THE
sp
ALKALI
sp
ANY
ALKALINE
sp
USE
sp
C
A
sp
O
H
TWICE
sp
FOR
THE
BASE
sp
C
A
sp
O
sp
CALCIUM
sp
OXIDE
sp
AND
sp
FOR
THE
sp
CARBONATE
sp
C
A
sp
C
O
sp
THREE
sp
THE
METAL
sp
JUST
CALCIUM
sp
OKAY
YEAH
sp
SO
sp
YOU
CAN
WORK
sp
THROUGH
THOSE
sp
WITH
EACH
OF
THE
sp
ACIDS
sp
SO
GO
sp
THROUGH
sp
WITH
H
sp
C
L
sp
RIGHT
sp
OKAY
sp
YEAH
AND
sp
JUST
GO
sp
STRAIGHT
sp
THROUGH
THAT
sp
WHAT
sp
HAPPENS
THEN
GO
THROUGH
AGAIN
sp
WITH
sp
WHICHEVER
sp
ONE
YOU
WANT
sp
TO
DO
NEXT
H
TWO
S
sp
O
sp
FOUR
sp
YEAH
sp
AND
THEN
GO
sp
THROUGH
AGAIN
sp
WITH
sp
NITRIC
sp
ACID
sp
IN
EACH
CASE
sp
YOU
YOU
DID
IT
sp
THIS
IS
WHAT
I
LIKE
sp
YOU
WENT
STRAIGHT
sp
FOR
IT
YOU
WENT
STRAIGHT
FOR
THE
sp
SALT
ON
THE
MOST
sp
DIFFICULT
sp
ONE
sp
THE
CARBONATE
RIGHT
sp
IT'S
sp
GOING
sp
TO
BE
sp
CALCIUM
sp
CHLORIDE
YOU
sp
GOT
sp
THAT
sp
OUT
AND
sp
YOU
sp
FOUND
sp
THIS
sp
HORRIBLE
sp
HYDROGEN
sp
CARBONATE
sp
THING
sp
LEFT
sp
OVER
MM
sp
SO
sp
YOU
CAN
DO
sp
YOU
CAN
USE
EXACTLY
THE
sp
SAME
SYSTEM
YOU
sp
USED
ON
sp
THAT
FOR
WORKING
OUT
EACH
ONE
sp
AND
sp
SEE
WHAT
sp
HAPPENS
sp
NOW
ARE
YOU
HAPPY
WITH
sp
THAT
sp
THAT
YOU
CAN
DO
THAT
OR
DO
YOU
THINK
THAT'S
SORT
OF
OVERLOADING
YOU
NO
sp
THAT'S
sp
FINE
I
I
TH
I'M
QUITE
SURE
THAT
sp
YOU
CAN
sp
GO
sp
THROUGH
THAT
BECAUSE
YOU'RE
RECOGNIZING
THE
PATTERNS
sp
MUCH
sp
MORE
NOW
sp
YOU'RE
sp
ACCEPTING
MORE
THINGS
sp
AS
sp
OH
YEAH
sp
YOU
DON'T
sp
NEED
TO
TELL
ME
sp
THAT
sp
I
sp
KNOW
IT
YEAH
sp
I
sp
CAN
sp
FEEL
THIS
sp
COMING
sp
BACK
sp
MUCH
sp
MORE
RATHER
sp
THAN
sp
TELL
ME
THAT
AGAIN
sp
WHY
IS
IS
sp
CALLED
A
sp
CHLORIDE
sp
WHY
IS
IS
sp
CALLED
sp
A
sp
SULPHATE
RIGHT
sp
SO
YOU
RECOGNIZE
sp
THESE
sp
PATTERNS
sp
YEAH
sp
OKAY
sp
YEAH
ERM
NOW
sp
NEXT
sp
WEEK
sp
YOU
WERE
SAYING
sp
SOMETHING
ABOUT
sp
YOU'D
sp
LIKE

MONDAY
sp
I
WON'T

BE
HERE
MHM

YOU'D
MISUNDERSTOOD
sp
YEAH
sp
NOW

CAN
YOU
WRITE
OUT
sp
EITHER

BEFORE
sp
I
OR

YEAH
I
JUST
WAN

ERM
sp
CAN
YOU
REMEMBER

WHAT
sp
YOU'RE
GOING
sp
TO
DO
LEARN
sp
SOME
sp
OF
sp
THESE
sp
RIGHT
TAKING
sp
CALCIUM
AS
THE
METAL
sp
YOU
sp
WANT
sp
TO
sp
WRITE
EQUATIONS
sp
FOR
sp
EACH
sp
OF
THE
sp
FOUR
TYPES
OF
sp
REACTION
sp
DO
YOU
sp
REMEMBER
WHAT
THOSE
sp
FOUR
sp
TYPES
sp
WHERE
OR
ANY
sp
ER
sp
OF
THOSE
sp
FOUR
sp
TYPES
sp
YEAH
sp
GO
ON
ER
sp
BASES
sp
RIGHT
sp
ALKALIS
sp
YEAH
sp
CARBONATES
sp
RIGHT
ERM
sp
AND
THE
sp
MOST
sp
SIMPLE
sp
ONE
sp
WHICH
IS
sp
THE
HARDEST
TO
REMEMBER
sp
COS
sp
IT'S
sp
SO
OBVIOUS
sp
YEAH
sp
ERM
sp
OH
SHOOT
sp
WHAT
sp
WAS
sp
IT
sp
TAKING
sp
CALCIUM
DID
sp
WE
SAY
sp
YEAH
sp
YEAH
sp
AS
sp
THE
sp
METALS
sp
METALS
sp
JUST
sp
THE
METAL
sp
YEAH
sp
JUST
THE
METAL
sp
PLUS
sp
THE
sp
ACID
sp
RIGHT
OKAY
sp
SO
sp
GO
THROUGH
sp
USE
CALCIUM
sp
GO
sp
THROUGH
sp
EACH
OF
THE
sp
FOUR
REACTIONS
sp
MM
YEAH
SO
sp
USE
CALCIUM
sp
HYDROXIDE
sp
WHICH
sp
IS
WRITTEN
ON
sp
THERE
AS
sp
THE
MHM
ALKALI
sp
CALCIUM
sp
OXIDE
AS
sp
THE
BASE
sp
CALCIUM
sp
ITSELF
sp
AS
sp
THE
sp
METAL
CALCIUM
sp
CARBONATE
AS
sp
THE
CARBONATE
sp
WE
GOT
FOUR
TYPES
sp
OF
REACTION
sp
USING
sp
FIRST
sp
H
sp
C
L
sp
OKAY
sp
SO
sp
WRITE
THAT
sp
IN
USING
sp
FIRST
sp
H
C
L
sp
THEN
sp
H
N
sp
O
THREE
sp
THEN
sp
H
TWO
S
sp
O
FOUR
sp
RIGHT
sp
AND
THEY'RE
ALL
sp
THEY'RE
sp
THEY'RE
ALL
sp
PATTERNS
sp
WITHIN
sp
LOTS
OF
sp
SIMILARITIES
sp
BY
GOING
sp
THROUGH
IT
A
sp
FEW
TIMES
LIKE
sp
THAT
sp
AND
sp
WHEN
YOU
sp
WHEN
YOU'VE
DONE
sp
THAT
GO
THROUGH
AGAIN
sp
SAY
AND
WITH
sp
AND
sp
EVERYWHERE
sp
YOU
COULD
sp
WRITE
THE
sp
WHOLE
LOT
sp
OUT
sp
AGAIN
YEAH
sp
AND
EVERYWHERE
YOU'VE
GOT
sp
AN
A
sp
C
A
sp
YOU
COULD
sp
PUT
AN

M
G
sp
AND
EVERYTHING
sp
WOULD
FIT
sp
BECAUSE
IT'S
sp
C
A
DOUBLE
sp
POSITIVE
sp
M
G
DOUBLE
sp
POSITIVE
sp
RIGHT
sp
YOU
sp
COULD
GO
sp
THROUGH
sp
AGAIN
AND
sp
YOU
sp
COULD
sp
PUT
SODIUM
sp
INSTEAD
sp
OF
THAT
sp
M
sp
G
sp
BUT
sp
WHERE
YOU
HAD
sp
THINGS
sp
LIKE
sp
M
G
sp
O
sp
H
sp
TWICE
sp
YOU'D
JUST
HAVE
N

A
O
H
sp
SO
YOU'D
HAVE
A
HAVE

TO
DO
A
LITTLE

CHANGING
ABOUT
ARE
YOU
HAPPY

THAT
YEAH
YOU

CAN
DO
THAT
AND
sp
DON'T
FORGET
sp
FOR

TWENTY
EIGHTH

NINTH
sp
YOU
CAN

WAS
sp
SORT
OF
sp
UP
sp
TO
DATE
sp
ENGLISH
USAGE

I

THINK

I'LL
JUST
sp
TAKE
sp
THOSE
SHEETS
I
sp
SAID
I
sp
WOULD
GIVE
YOU
sp
SO
sp
YOU
USED
TO
sp
SAY
IN

sp
THINGS
LIKE

sp
BE
GRATEFUL
sp
IF
sp
MM
sp
NOBODY
REALLY
SAYS
sp
THAT
ANY
MORE
THEY
SAY
sp
I
WOULD
sp
BE
THEY
DON'T
sp
BOTHER
SAYING

I

I
GOT
sp
THAT
sp
WITH

MY
sp
INTERVIEW
sp
AT

I
SHOULD
sp
BE
GRATEFUL
IF
sp
YOU
sp

sp
MM
sp
OR

sp
IT'S
sp
GRAMMATICAL
OR
I
WILL
BE
GRATEFUL
YEAH
sp
IT'S
GRAMMATICALLY
sp
CORRECT
YEAH
sp
BUT
SOON
IT
WILL
sp
BE
sp
APPEARING
IN
A
DICTIONARY
AS
sp
A
BIT
OVER
FORMAL
sp
A
BIT
sp
ARCHAIC
sp
USE
IT
IF
YOU
LIKE
sp
IN
A
BUSINESS
sp
LETTER
sp
BUT
MOST
sp
PEOPLE
sp
WOULD
sp
PREFER
IT'S
WAY
DOWN
sp
THE
sp
I
MEAN
ALL
THESE
PEOPLE
GO
OH
IT'S
sp
PEOPLE
AREN'T
USING
THE
ENGLISH
LANGUAGE
PROPERLY
BUT
IF
sp
YOU
LOOK
AT
sp
THE
ENGLISH
LANGUAGE
sp
TWO
HUNDRED
YEARS
AGO
EXACTLY
sp
IT
WAS
sp
NOTHING
LIKE
sp
WHAT
IT
IS
sp
TODAY
sp
IT'S
DEVELOPED
sp
IT
CHANGES
ITS
sp
FORM
AND
sp
IT'S
YEAH
sp
LIKE
A
sp
LIFE
FORM
IT'S
sp
RIGHT
sp
THEY
GO
ON
ABOUT
SHAKESPEARE
sp
AND
{OOV}
sp
CHAUCER
BUT
IF
YOU
SPOKE
sp
TO
THEM
THE
WAY
CHAUCER
USED
TO
SPEAK
THEY
WOULDN'T
UNDERSTAND
A
WORD
YOU
WERE
SAYING
THEY
WOULDN'T
UNDERSTAND
sp
WHEREAS
WE
CAN
JUST
ABOUT
UNDERSTAND
CHAUCER
sp
YEAH
sp
SO
AS
YOU
sp
SAY
IT'S
sp
A
IT'S
sp
A
sp
DEVELOPING
sp
THING
sp
AND
THE
ONLY
A
LIFE
FORM

IT'S
GROWING

sp
THE

TO
GET

WORDS
sp
THAT
sp
ARE
sp
IN
sp
THE
sp
DICTIONARY
