Half-Reactions
« on: November 12, 2010, 08:53:08 PM »
O2 + 4Cu -----> 2Cu2O

The reduction half-reaction I got was:
O2+4e- ----> 2O^2-

Oxidation half-reaction:

Cu----> 2 Cu+2 + 4e-

I know my oxidation half reaction is wrong but i dont know why ! I can't fo half-reactions for some reason and I dont know why. I'm going crazy please help me someone! A nice explanation would be so greaat!!!!!

Is your oxidation reaction balanced?
