Limiting Reagent and Percent Yield Worksheet Name Period
1. When copper (II) chloride reacts with sodium nitrate, copper (II) nitrate and sodium chloride are formed.
The balanced chemical equation is:
CuCl2 + 2 NaNO3 Cu(NO3)2 + 2 NaCl
a. 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 limiting reagent?
c. How many grams of copper(II) nitrate is formed?
d. If 11.3 grams of sodium chloride are actually formed in the reaction described in problem #1, what is the
percent yield of this reaction?
2. When lead (II) nitrate reacts with sodium iodide, sodium nitrate and lead (II) iodide are formed. The
balanced chemical equation is:
Pb(NO3)2 (aq) + 2 NaI (aq) PbI2 (s) + 2 NaNO3 (aq)
a. If I start with 25.0 grams of lead (II) nitrate and 15.0 grams of sodium iodide, how many grams of
sodium nitrate can be formed?
b. What is the limiting reagent?
