Problem Details

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 in grams? 

(c) If the yield of the reaction is 71.1%, what is the actual yield (grams) of chlorine?
