A chemical equation is said to be balanced if:
(a) the atoms of different elements on both sides of the equations are equal.
(b) the equation is molecular, i.e. the gases if involved in the equation must be in the molecular form (e.g. H2, O2, N2, Cl2, etc.).
Necessity to balance chemical equations: The chemical equations have to be balanced to fulfil the requirement of law of conservation of mass. According to the law, the total mass of reactants
