Zinc-air batteries are metal-air batteries powered by oxidizing zinc with oxygen from the air. These batteries have high energy densities and are relatively inexpensive to produce. Given the net reaction of zinc-air battery as: 2Zn(s)+02(g)2ZnOs And the two half reactions are: Zns+2OH(aq)ZnOs+H2Ol+2e (Anode) SRP: 1.27V 02g+2H2Ol+4e4OHaq (Cathode) SRP: 0.4V a. Calculate the standard voltage of zinc-air cell. b. Calculate the theoretical specific capacity of the cell. c. Calculate the theoretical specific energy of the cell
