    Thanks for your response on the oxidation reduction it was helpful, but how do you balance equations without oxygen?
    such as Cu2+Fe------->Cu+Fe2
    I started out with Cu2-->Cu
    Cu2+---2Cu
    and on the oxidation side Fe-->Fe2+
    Fe-->Fe2+2e
    and what about this one?
    Sn2+2Fe)3+----Sn)4+ 2Fe)2+

    You are correct! You want to start with the half reactions.

    Cu2+ --> 2Cu

    Start by balancing mass. So we need a 2 on the left:

    2Cu2+ --> 2Cu

    Now balance charge. We need ...
