A button cell used in watches functions as following Zn(s) + Ag2O(s) + H2O(l) <=> 2Ag(s) + Zn 2+ (aq) + 2OH - (aq) If half cell potentials are Zn 2+ (aq) + 2e - -> Zn(s) ; E = -0.76 V Ag2O(s) + H2O(l) + 2e - -> 2Ag(s) + 2OH - (aq) , E = 0.34 V The cell potential will be

1. A. 1.10 V
2. B. 0.42 V
3. C. 0.84 V
4. D. 1.34 V
