Everyday household items such as flashlights and radios use alkaline batteries. The overall reaction in the battery is as follows: Zn(s) + 2 MnO2(s) ⇌ ZnO(s) + Mn2O3(s). Using a reliable source, give the two half-reactions that occur in the battery and calculate the standard emf generated by the voltaic cell.
