Given the following half-reactions occurring in the silver-zinc hearing aid battery, calculate the voltage at 25 °C of this battery.

ZnO(s) + H2O(l) + 2 e-→ Zn(s) + 2 OH-(aq) E° = -1.260 V
Ag2O(s) + H2O(l) + 2 e-→ 2 Ag(s) + 2 OH-(aq) E° = +0.342 V


▸ +1.602 V

▸ +1.402 V

▸ +0.858 V

▸ -0.858 V

▸ -1.602 V
