Part D
Sn2+(aq) + 2 e Sn(s) E0 = -0.14V
Ni(s) Ni2+(aq) + 2e E0 = 0.23V
--------------------------------------------------------------
Sn+2 (aq) + Ni(s) ------> Ni+2 +Sn(s) E0cell = 0.09V
D. +0.09 volts
Zn -----------------> Zn+2 + 2e- E0 = + 0.76V
2Ag+1 +2e- --------> 2Ag(s) E0 = 1.98V
-----------------------------------------------------------------------------------------
Zn(s) + 2Ag+ (aq) ---------> Zn+2 (aq) + 2Ag(s) E0cell = 2.74V
C. 2.74 volts
