Cu^+ (aq) + Zn^2+ (aq) -----------------> Cu^2+ (aq) + Zn(s)
2Cu^+ (aq) ---------------> 2Cu^2+ (aq) + 2e^- E0 = -0.16v
Zn^2+ (aq) + 2e^- ------------> Zn(s) E0 = -0.76v
-----------------------------------------------------------------------------------------
Cu^+ (aq) + Zn^2+ (aq) -------> Cu^2+ (aq) + Zn(s) E0cell = -0.92v
will Cu^+ be able to reduce Zn^2+ to Zn NO
Ce^3+ (aq) --------> Ce^4+ (aq) + e^- E0 = -1.70v
Ag^+ (aq) + e^- -------> Ag(s) E0 = 1.99v
----------------------------------------------------------------------------
Ce^3+(aq) + Ag^+ (aq) --------> Ce^4+ (aq) + Ag(s) E0cell = 0.29v
will Ce^3+ be able to reduce Ag^+ to Ag YES
