6. A silver oxide-zinc cell maintains a fairly constant voltage during discharge (1.60 V·The button form of this cell is used in watches, hearing aids, and other electronic devices. The half reactions are: Zn(s) + 20H (aq)→Zn(OH) + 2e Ag 20 (z)+ H2O(l) + 2e . →2Ag(s) + 20H . (aq) 2(3) Identify the anode and the cathode reactions. What is the overall reaction in the voltaic cell?
