If the following half-reactions are used in an electrolytic cell: Ag+(aq) + e− ⟶ Ag(s) Eo = 0.80 V Ca2+(aq) + 2 e− ⟶ Ca(s) Eo = −2.76 V Click here for a copy of Final Exam cover sheet.

1) The metal solid that is plated out at the cathode is [Ag(s), Ca(s)]

2) It would take [3, 8. 16] hours to deposit 60 g of the solid with a current of 5.0 A.
