Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide. 4 HCl ( aq ) + MnO 2 ( s ) ⟶ MnCl 2 ( aq ) + 2 H 2 O ( l ) + Cl 2 ( g ) A sample of 33.3 g MnO 2 is added to a solution containing 45.9 g HCl . What is the limiting reactant? HCl MnO 2 What is the theoretical yield of Cl 2 ? theoretical yield: g Cl 2 If the yield of the reaction is 81.7 % , what is the actual yield of chlorine? actual yield:
