I'm trying to figure out this reaction, and I know I have something wrong, I'm just not sure what.
CuSO4+NaHCO3=CuCO3+NaSO4+CO2+H2O
So my question is, what is the correct reaction since this cannot be balanced.
EDIT: Sorry, this should be in beginnings, my bad, I wasn't paying attention.

1. I think you mean Na2SO4 rather than NaSO4
2. Once you make that change, it believe balances as 2CuSO4 + 2NaHCO3 = 2CuCO3 + H2 + 2NaSO4

Actually I believe the balanced reaction should be as follows:
CuSO4 + 2 NaHCO3 ==> CuCO3 + Na2SO4 + CO2 + H2O

Thank you very much! It was starting to bug me.

If you get bogged down with one of these try the half reaction approach. I bet the "NaSO4" wouldn't have appeared.

Half-reaction approach? We are not talking about redox here. This is just a precipitation of copper(II) carbonate and decomposition of carbonic acid.
