Detailed Solution

Concept- A balanced chemical equation is the equation which has the equal number of atoms present on both sides of the equation.
We should balance the chemical equation because it is necessary. According to the law of mass conservation, the mass neither be created nor be destroyed during a chemical reaction. So, after balancing the equation we can state that the mass can neither be created nor destroyed.
Thus, to balance the equation, we keep the count of the elements balanced on both sides of the reaction which maintains the same total mass of elements on both sides.
Therefore, chemical equations are balanced according to the Law of Conservation of Mass.
Hence, A balanced equation has an equal number of atoms on the reactant side and on the product side.
