Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide.
4HCl(aq) + MnO2(s) → MnCl2(aq) + 2H2O(l) + Cl2(g)
You add 35.5 g of MnO2 to a solution containing 42.5 g of HCI.
(a) What is the limiting reactant?
(b) What is the theoretical yield of Cl 2 in grams?
(c) If the yield of the reaction is 71.1%, what is the actual yield (grams) of chlorine?
