A chemical change is an irreversible change. In this change original substances are not obtained back and entirely new substance or substances are formed as a result of reaction between chemicals and substances. The chemical change is also called chemical reaction. In chemical reaction or change, the substances which take part in bringing about the change in a reaction is called reactants and the substances produced as a result of reaction are called products.
