The standard electrode potentials for two half‑cells are:

\text{Zn}^{2+} + 2e^- \rightarrow \text{Zn} \quad E^\circ = -0.76\,\text{V}

\text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \quad E^\circ = +0.34\,\text{V}

What is the cell potential,

E^\circ_{\text{cell}}

, for a simple cell made from these two half‑cells?
