Quantitative chemistry – loop game
The positive
electrode.
The sum of the
relative atomic
masses of the
atoms in the
formula.
Start:
Law of
conservation
of mass
No atoms are
made or lost in a
reaction so the
mass of the
products is always
equal to the mass
of the reactants.
Relative
formula mass
Atomic mass
The total number
of protons and
neutrons in an
atom.
Mr
Balanced
equation
An equation where
the number of
atoms of each
element is the
same on each side.
Mole
Ar
The symbol
representing
relative atomic
mass.
Avogadro
constant
mol
The symbol
representing
moles.
Percentage
yield
Yield
The amount of
product made in a
reaction.
Concentration
of a solution
The symbol
representing
relative formula
mass.
A unit to measure
amounts of
chemicals e.g.
atoms, molecules,
ions and electrons.
23
6 x 10
The amount of
product actually
made in a reaction
compared with the
amount that could
theoretically be
made.

An acid that is
completely ionised
such as nitric,
hydrochloric, and
sulfuric.
pH
A measure of the
hydrogen ion
concentration of
an acid.
Weak acid

partially ionised
such as ethanoic,
citric and
carbonic.

Teaching notes
There are 32 cards, allowing it to be used with a whole class. The activity could also be
done individually, in pairs or in small groups to produce a complete ordered set of cards.
Before the lesson print out the tables, ideally onto card so they can be used again. If
multiple sets are produced, print them onto different coloured card. Each table needs to
be cut down the middle and horizontally to create 32 individual domino cards.
1. Distribute the cards between members of the group.
2. Students may place the cards in front of them or keep them hidden.
3. Explain that it is a bit like dominoes. A keyword or phrase is read out and
someone within the group or class has the matching description. They read out
the followed by the next keyword.
4. The student who receives the card with ‘start’ on it reads out the first question.
5. The students look at their cards. The one who thinks they have the answer puts
their hand up and reads it out. If it is correct, they will then read out the next
question. Completed cards are placed face down on the bench.
6. The exercise continues until the ‘starter’ gives the final answer.
