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) A sample of 40.3 g MnO2 is added to a solution containing 42.1 g HCl.

What is the limiting reactant?

HCl or MnO2

What is the theoretical yield of Cl2?

theoretical yield: g Cl2

If the yield of the reaction is 79.9%, what is the actual yield of chlorine?

actual yield: gCI2
