(a) Interpretation: The given oxidation-reduction reaction is to be balanced. Concept Introduction: In a chemical equation when the number of atoms of an element on the left-hand side is equal to the number of atoms of that element on the right-hand side, it is known as a balanced chemical equation. The balancing of a chemical equation is done to follow the law of conservation of mass.
