2 ) CaO +H2O --------->Ca(OH)2
3 ) 2FeSO4 ----------->Fe2O3 + SO2 + SO3
4 ) NH4Cl -----------> NH3 + HCl
5 ) 2Ca + O2 ---------->2CaO​

Answer 1

Explanation:

1. Decomposition reaction since two kinds of products are formed from one kind of reactant.

2. Combination reaction since two kind of reactants combined to give one kind of product.

3. Decomposition reaction since three kinds of products are formed from one kind of reactant.
