A chemical equation is a statement that describes a chemical reaction in terms of symbol and formulae.
It is necessary to balance a chemical equation in order to follow the law of conservation of mass, which states, " the total mass on the side of reactants is always equal to the total mass on the side of products."

Answer:
Explanation:
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
