KS3 Chemistry Questions– Chemical Equations


1. In a chemical equation, reactants will interact to form _______.

a. Mixtures
b. Products
c. More reactants
d. Catalyst
e. Water

2. The compounds created will always have very similar properties to the reactants.

a. True
b. False

3. The catalyst is another reactant.

a. True
b. False

4. You must always have the same number of atoms on each side of the equation.

a. True
b. False

5. Where in the chemical equation is the catalyst written?

a. On the left
b. On the right
c. On top of the arrow
d. Below the arrow
e. The catalyst is never written

1.b. Products

2.b. False

3.b. False

4.a. True

5.c. On top of the arrow


1. What is conservation of mass?

2. What is the difference between a word equation and a balanced equation?

3. What does diatomic mean?

4. What is the role of a catalyst?

5. What will happen in a chemical reaction?

6. Balance the following equations (The chemical symbols are correct, you just need to balance) :

a. H2 + Cl2 HCl

b. H2 + O2 H2O

c. Na + Cl2 NaCl

d. CH4 + O2 CO2 + H2O

[bg_collapse view=”link” color=”#fafafa” expand_text=”Reveal Answer” collapse_text=”Hide Answer” inline_css=”background: #2ea3f2; padding: 9px; font-size: 14px; font-weight: 600;” ]

In a reaction, no new atoms will be created and none of the atoms will be lost – this is conservation of mass.
2.A word equation only has the name of the compounds in the equation, but a balanced equation has the chemical symbols and the numbers of the atoms.3.Diatomic means that the atoms of a single element like to travel in pairs , like oxygen or chlorine.

4.A catalyst is used in order to speed up a reaction but it isn’t actually part of the reaction.

5.In a chemical reaction, two or more compounds/elements will interact and change the arrangement of their atoms to create new compounds.

a. H2 + Cl2 2HCl
b. 2H2+ O2 2H2O
c. 2Na + Cl2 2NaCl
d. CH4 + 2O2 CO2 + 2H2O
