I'm going to need some help getting this problem started
Calculate E for the following electrochemial cell at 25 degrees Celsius
Pt(s) ! Sn^2+(aq, 0.50M), Sn^4+(aq, 0.50Mz0 !! I^-(aq, 0.15M) ! AgI(s) !Ag(s) given the following standard reduction potentials
AgI(s) + e^- ==> Ag(s) + I^-(aq) E naught = -0.15V
Sn^4+(aq) + 2e^- ==> Sn^2+)aq) E naught = +0.15V
