1. 100 g of manganese dioxide reacts with 300 g of hydrochloric acid in the reaction shown below.
MnO2+ 4HCl -> MnCl2 + 2H2O + Cl2

(Use the following molar masses:
MnO2 = 86.9g / mol; HCl = 36.5g / mol Cl2= 125.8g / mol ; H2O = 18.02g / mol and
Cl2 =70.9 g/mol

a. Which reactant is limiting?
b. Which reactant is excess?
c. What is the theoretical yield of Cl2?
d. What is the percent yield of the reaction if 75.0 g of Cl2 was produced?​
