(A) The Nernst equation for the cell reaction is given by: $E_{cell} = E^\circ_{cell} - \frac{0.059}{n} \log \frac{[Zn^{2+}]}{[Cu^{2+}]}$ Here,$n = 2$ (number of electrons transferred). Given: $E^\circ_{cell} = 1.10 \, V$,$[Zn^{2+}] = 0.1 \, M$,and $[Cu^{2+}] = 0.1 \, M$. Substituting the values: $E_{cell} = 1.10 - \frac{0.059}{2} \log \frac{0.1}{0.1}$ Since $\log(1) = 0$,the term $\frac{0.059}{2} \log(1) = 0$. Therefore,$E_{cell} = 1.10 - 0 = 1.10 \, V$.
