Detailed explanation-1: -All chemical equations must be balanced because matter cannot be created or destroyed in chemical reactions. A chemical reaction occurs when some substances change chemically to other substances.
Detailed explanation-2: -The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. Thus, the amount of matter cannot change. Because mass is always conserved in chemical reactions, balanced chemical equations have the same number and type of each atom on both sides of the equation.
Detailed explanation-3: -The balancing of the chemical equation is done to satisfy the law of conservation of mass, i.e. “Total mass of all the products of the reaction in a chemical reaction is equal to the total mass of all the reactants".
Detailed explanation-4: -Answer: (C) The chemical composition of the reactants is the same before and after the reaction.
Detailed explanation-5: -1 Answer. A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
