Answer #1

Cd(s) -------------> Cd^2+ (aq) + 2e^-               E0 = 0.40v

Sn^4+ (aq) + 2e^- -----> Sn^4+(aq)                 E0 = 0.15v

----------------------------------------------------------------------------------------

Cd(s) + Sn^4+ (aq) ------> Cd^2+ 9aq) + Sn^4+ (aq)   E0cell = 0.55v

a. +0.55V >>>>answer
