Why is it necessary to balance a chemical equation |
|
Answer» The chemical equation needs to balance because of law of conservation of mass. 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. It is necessary to balance because to obey the law of conservation of mass ie. Mass of reactant is equal to mass of product |
