What is the standard cell potential, \( E_{cell}^{\ominus} \), of the following cell consisting of an \( Ag(s) \) electrode in \( Ag^+(aq) \) and an \( Mg(s) \) electrode in \( Mg^{2+}(aq) \)?
\( Ag^+(aq) + e^- \rightleftharpoons Ag(s) \) (\( E^{\ominus} = +0.80V \))
\( Mg^{2+}(aq) + 2e^- \rightleftharpoons Mg(s) \) (\( E^{\ominus} = -2.37V \))
