Balence reactions
Not what you're looking for?
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+

Solution Summary
It shows how to balance the chemical reaction.
Solution Preview
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 ...
