Assume that you have following items and any other necessary equipment. H2 gas, O2 gas, de-ionized water, Li metal, Lit ion-containing proper solution of any concentration, Zn metal, Zn2+ ion-containing proper solution of any concentration. (A) Suggest every (theoretically) possible Galvanic cells. The answer must include half-cell reactions, balanced overall reaction, and Ecell- (B) Identify the strongest reducing agent and justify your answer. (C) If one of the systems suggested in (A) consumes 50g of Zn metal for 2h operation, how much is the current? How many grams of H2 can be obtained from water using the charges of this system
