Answer the following questions based on the following electrochemical reaction:

Al(s) + Cu 2+(aq) <====> Cu(s) + Al3+ (aq)

Write the balanced chemical equation for this cell.

I'm confused.. how would this be balanced?
Answered by bobpursley
mass is balanced on each side, as well as electrons. Each Cu ion has to receive two electrons, and each Al atom donate three

2Al(s) + 3Cu 2+(aq) <====> 3Cu(s) + 2Al3+ (aq)

so, six electrons were donated, and six received, and the mass is the same on each side.
