    The equation is:

    3 O₂ + 4 Co → 2 Co₂O₃

    Oxidation half reaction:

    Co → Co³⁺ + 3 e

    Reduction half reaction:

    O₂ + 4 e → 2 O²⁻

    To balance the equation number of electrons lost must be equal to number or electrons gained so we must multiply oxidation half time 4 and reduction half times 3
