Properties of a decomposition reaction

A chemical reaction is defined as the combination of substances called reactants to form a product. The various types of chemical reaction include:

• synthesis reaction

• combustion reaction

• decomposition reaction

• single or double replacement reaction

Decomposition reaction is that type of chemical reaction in which the reactant breaks down to form two or more products.
