First, verify that the equation contains the same type and number of atoms on both sides of the equation. Step 5. A redox reaction is nothing but both oxidation and reduction reactions taking place simultaneously. To make the two equal, multiply the coefficients of all species by integers producing the lowest common multiple between the half-reactions. Identify which reactants are being oxidized (the oxidation number increases when it reacts) and which are being reduced (the oxidation number goes down). To balance KMnO4 + heat = K2MnO4 + MnO2 + O2 you'll need to be sure to count all of atoms on each side of the chemical equation. {Date of access}.
