636 grams of Na2CO3(s) are disolved in 3.0 liters of aqueous solution
For the cell diagram Pt(s)|H2(g)|H+(aq)||Cu2+(aq)|Cu(s) Write a balanced equation for the half-reaction at the cathode. The cathode is the site of reduction so copper gets reduced. So wouldn't the answer be: Cu2+(aq) -> Cu(s) + 2e-?
