1. Take the reaction: NH3 + O2
NO + H2O. In an experiment, 3.25 g of NH3 are allowed to react
with 3.50 g of O2.
a. Which reactant is the limiting reagent?
b. How many grams of NO are formed?
c. How much of the excess reactant remains after the reaction?
2.
limiting, assuming we started with 30.0 grams of ammonium nitrate and 50.0 grams of sodium
phosphate. What is the mass of each product that can be formed? What mass of the excess
reactant(s) is left over?

If 15 grams of copper (II) chloride react with 20. grams of sodium nitrate, how much
sodium chloride can be formed?
b. What is the name of the limiting reagent? __________________

4.
A research supervisor told a chemist to make 100 g of chlorobenzene from the reaction of
benzene with chlorine and to expect a yield no higher that 65%. What is the minimum quantity
of benzene that can give 100 g of chlorobenzene if the yield is 65%? The equation for the
reaction is:
C6H6 + Cl2 -----------> C6H5Cl + HCl
benzene
chlorobenzene
