Solution
The chemical equations are balanced to satisfy one of the following laws in chemical reactions. This law is known as law of conservation of mass.
Explanation:
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction. Consequently, the total mass of the reactants must exactly equal the total mass of the products. To obey this law, we balance chemical equations, ensuring that the exact number of atoms of each element is identical on both sides of the reaction.
