    Original equation:

    CuO2 + NH3 - - > H2O + N2 + Cu

    To write a balanced equation, you multiply a compound or element ie. NH3 by a number in front so that the reactant side and product side have the same number of atoms.

    3CuO2 + 4NH3 - - > 6H2O + 2N2 + 3Cu

    3CuO2 - solid

    4NH3 - gas

    6H2O - liquid

    2N2 - gas

    3Cu - solid
