b) Fe|Fe2+(0.10 M)||Cu2+(0.10 M)|Cu

c) Pb|Pb2+(0.10 M)||Cu2+(0.10 M)|Cu

d) Pb|Pb2+(0.10 M)||Zn2+(0.10 M)|Zn

e) Zn|Zn2+(0.10 M)||Fe2+(0.10 M)|Fe

f) Pb|Pb2+(0.10 M)||Fe2+(0.10 M)|Fe

Please help, thanks.

Use the table below to answer the questions that follow.

Half Reaction E°(V)

Ag+ + e- → Ag (s) +0.80

Cu2+ + 2e- → Cu (s) +0.34

Pb2+ + 2e- → Pb (s) -0.13

Ni2+ + 2e- → Ni (s) -0.28

(A) Calculate E°cell for a voltaic cell made with Ni, Ni2+and Ag, and Ag+.

(B) Which substance is Oxidized? (be sure to include the state of the oxidized substance in your answer)

Zn(s) + CuSO4(aq) --> ZnSO4(aq) + Cu(s)
