Include states of matter 2MnO,(s) +H,0(1) 2eMn,02 (s)+20H(aq)
Solution
Oxidation : Zn (s)Â Â ----------------> Zn2+ (aq) + 2e-
Reduction : 2 MnO2 (s) + H2O (l) + 2e- -----------> Mn2O3 (s) + 2 OH- (aq)
_____________________________________________________________
overall : Zn (s) + 2 MnO2 (s) + H2O (l) ----------> Zn2+ (aq) + Mn2O3 (s) + 2 OH- (aq)
balanced chemical equation for spontaneous redox reaction :
Zn (s) + 2 MnO2 (s) + H2O (l) ----------> Zn2+ (aq) + Mn2O3 (s) + 2 OH- (aq)

1. Answer the four questions below regarding a particular type of alkaline battery in which the
following half reactions are used: 4th attempt Part 1 (1 pt) d See Periodic Table See Hint Write
the balanced chemical equation for the spontaneous redox reaction. Include states of matter
2MnO,(s) +H,0(1) 2eMn,02 (s)+20H(aq)
Solution
Oxidation : Zn (s)Â Â ----------------> Zn2+ (aq) + 2e-
Reduction : 2 MnO2 (s) + H2O (l) + 2e- -----------> Mn2O3 (s) + 2 OH- (aq)
_____________________________________________________________
overall : Zn (s) + 2 MnO2 (s) + H2O (l) ----------> Zn2+ (aq) + Mn2O3 (s) + 2 OH- (aq)
balanced chemical equation for spontaneous redox reaction :
Zn (s) + 2 MnO2 (s) + H2O (l) ----------> Zn2+ (aq) + Mn2O3 (s) + 2 OH- (aq)
