According to Le Châtelier's Principle, if the equilibrium of a system is disturbed by a stress, the system will shift to compensate. When a chemical system is at equilibrium, there is no net change in the concentration of its reactants or products The aggregate redox species method (or ARS method) is a variation of the oxidation number change method for balancing redox equations.
