Question

Identify the type of each of the following chemical reactions.

1. The reaction of the heating of ferrous sulphate to form a ferric oxide, sulphur dioxide and sulphur trioxide gas.

2. The reaction between zinc and hydrochloric acid to form zinc chloride.

3. The reaction between hydrogen and chlorine gases and forming hydrogen chloride.

Answer 1

1. The reaction of the heating of ferrous sulphate to form ferric oxide, sulphur dioxide and sulphur trioxide gas is an example of a decomposition reaction.
2. The reaction between zinc and hydrochloric acid is a displacement reaction as zinc is displacing hydrogen.
3. The reaction between hydrogen gas and chlorine gas is a combination reaction as the reactants are combined to form hydrogen chloride.
