Example 1 Balance the following equation H 2 O 2 H 2 O It is an unbalanced equation sometimes also called a skeleton equation This means that there are UNEQUAL numbers at least one atom on each side of the arrow By the way a skeleton equation is not wrong it just hasn t been balanced yet Presenting it as being balanced would be To balance a redox equation using the half reaction method the equation is first divided into two half reactions one representing oxidation and one representing reduction The equations for the half reactions are then balanced for mass and charge and if necessary adjusted so that the number of electrons transferred in each equation is the same
