Write a balanced chemical equation for the overall reaction in each of the following galvanic cells.

(a) $\text{Ag}\left(\text{s}\right)|{\text{Ag}}^{\text{+}}\left(\text{aq}\right)\Vert {\text{Sn}}^{\text{4+}}\left(\text{aq}\right)\text{,}{\text{Sn}}^{\text{2+}}\left(\text{aq}\right)|\text{Pt}\left(\text{s}\right)$

(b) $\text{Al}\left(\text{s}\right)|{\text{Al}}^{\text{3+}}\left(\text{aq}\right)\Vert {\text{Cu}}^{\text{2+}}\left(\text{aq}\right)|\text{Cu}\left(\text{s}\right)$

(c) $\text{Pt}\left(\text{s}\right)|{\text{Fe}}^{\text{2+}}\left(\text{aq}\right),{\text{Fe}}^{\text{3+}}\left(\text{aq}\right)\Vert {\text{MnO}}_4{}^{\text{-}}\left(\text{aq}\right)\text{,}{\text{Mn}}^{\text{2+}}\left(\text{aq}\right)|\text{Pt}\left(\text{s}\right)$
