Academic Chemistry Review Problems Chapter 10
Mole Conversions and Limiting Reactants:
1) If 1.00 mole of copper reacts with
1.50 moles of sulfur, how many moles of copper (I) sulfide are produced?
2) If 25.0 g of manganese (IV) oxide
reacts with 25.0 g aluminum, what mass of manganese is produced?
3) If 3.00 L of sulfur dioxide gas react
with 4.50 L of oxygen gas, what is the volume of sulfur trioxide gas produced (assume constant conditions)?
4) Calculate the percent yield for each
of the following situations:
a. Actual yield: 4.62 g; theoretical
yield: 5.02 g
b. Actual yield 9.31 g; Theoretical
c. Actual yield 6.9 x 105
kg; theoretical yield: 8.2 x 10 kg6
5) A chemist burns 160. g of aluminum
solid in excess air to produce 260. g of solid aluminum oxide. Calculate the
theoretical yield and the percent yield.
6) If 5.45 g of solid potassium chlorate
are decomposed to form solid potassium chloride and 1.95 g of oxygen gas, what is the theoretical yield and percent yield
7) When 14.97 g of iron metal react
with chlorine gas, 42.47 g of product are formed. Calculate the theoretical yield
and the percent yield.
