Solution: Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric add with manganese(IV) oxide: 4HCI (aq) + MnO2 (s) → MnCI2 (aq) + 2H2O (l) + CI2 (g) You add 37.1 g of MnO2 to a solution

Problem

Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric add with manganese(IV) oxide: 

4HCI (aq) + MnO2 (s) → MnCI2 (aq) + 2H2O (l) + CI2 (g) 

You add 37.1 g of MnO2 to a solution containing 41.7 g of HCI. 

(a) What is the limiting reactant?  

                 • MnO2

                 • HCl

(b) What is the theoretical yield of CI2

(c) If the yield of the reaction is 78.5%, what is the actual yield of chlorine?
