The chemical reaction during low current discharge of a simple "dry cell" involves:
(unbalanced) Zn + MnO2 + NH4Cl → ZnCl2 + Mn2O3 + NH3 + H2O
What is the coefficient for zinc in the balanced equation that uses the lowest whole number ratios, and what is the limiting reagent for a process in which equal masses of reactants are mixed?
◦ coefficient 1 and limiting reagent Zn
◦ coefficient 2 and limiting reagent Zn
◦ coefficient 1 and limiting reagent MnO2
◦ coefficient 2 and limiting reagent MnO2
◦ coefficient 2 and limiting reagent NH4Cl
