$Cu ( s )+ Sn ^{2+}( aq ) \rightarrow Cu ^{2+}( aq )+ Sn ( s )$
$\left( E _{ Sn ^{2+} \mid Sn }^{0}=-0.16\, V , E _{ Cu ^{2+} \mid Cu }^{0}=0.34\, V \right.$ Take $F=96500\, C\, mol ^{-1}$ )
$Ca\left( s \right)|C{a^{ + 2}}_{\left( {aq.} \right)}||F{e^{ + 2}}_{\left( {aq} \right)}|Fe\left( s \right)$
$E_{C{a^{ + 2}}/Ca}^o = - 2.87\,V$ ; $E_{Fe/F{e^{ + 2}}}^o = 0.41\,V$
