3. Chemical Reactions / Percent Yield / Problem 7
The reaction of ammonia with carbon dioxide produces urea CH4N2O, a common fertilizer according to the following equation (note: the reaction is unbalanced):
NH3(aq) + CO2(aq) → CH4N2O(aq) + H2O(l)
A chemist uses 32.5 mg of NH3 with 89.6 mg of CO2 to produce 55.7 mg of urea in the industrial urea synthesis. Answer the following questions:
(a) What is the limiting reactant?
(b) What is the theoretical yield of urea?
(c) What is the percent yield for the reaction?
