1. Ammonia gas can be prepared by the following unbalanced equation:

_____ CaO(s) + _____ NH4Cl (s) --> _____ NH3(g) + _____ H2O(g) + _____ CaCl2(s)

a. Balance the equation.
CaO + 2NH4Cl = 2NH3 + H2O + CaCl2

b. Suppose you begin this reaction with 112. grams of CaO and 224. grams of NH4Cl. Which is the limiting reagent?

c. What is the theoretical yield of NH3 in grams?

d. What mass of CaCl2 is also formed?

e. What mass of which reagent (starting material) is “left over” at the end of this process?

f. If the actual yield of NH3 is 55.6 grams, find the percent yield of NH3.
