(a)

Interpretation Introduction

Interpretation:

The value of ${\text{ν}}_{\text{e}}$ in the Nernst equation for given equation has to be calculated.

    ${\text{Cu}}_{\text{(s)}}{\text{ + Mg}}^{\text{2+}}{}_{\text{(aq)}}\stackrel{}{\to }{\text{Cu}}^{\text{2+}}{}_{\text{(aq)}}{\text{ + Mg}}_{\text{(s)}}$

(b)

Interpretation Introduction

Interpretation:

The value of ${\text{ν}}_{\text{e}}$ in the Nernst equation for given equation has to be calculated.

    ${\text{2 H}}_{\text{2}}{\text{O}}_{\text{(l)}}{\text{ + 2 Na}}_{\text{(s)}}\stackrel{}{\to }{\text{2 Na}}^{\text{+}}{}_{\text{(aq)}}{\text{ + 2 OH}}^{\text{-}}{}_{\text{(aq)}}{\text{ + H}}_{\text{2}}{}_{\text{(g)}}$
