Given the following balanced chemical reaction:

MnO2 + 4HCl → MnCl2 + Cl2 + 2H2O(g)

If 17.4 g of MnO2 is reacted with 18.4g of HCl how many g of Cl2 can theoretically be produced?

a. 14 g

b. 144.7 g

c. 75.7 g

d. 8.95 g

Expert Solution

answer : d). 8.95 g

MnO2 + 4HCl -----------------> MnCl2 + Cl2 + 2H2O(g)

86.94 g 145.84 g 125.84 70.906 g

17.4 g 18.4 g ??

here limiting reagent is HCl . so product formed based on this.

145.84 g HCl -----------------> 70.096 g Cl2

18.4 g HCl -------------------> ??

mass of Cl2 produced = 18.4 x 70.906 / 145.84 = 8.95 g

theoretical mass of Cl2 = 8.95 g
