Chapter 8, Problem 93E

Urea (CH₄N₂ O), a common fertilizer, can be synthesized by the reaction of ammonia (NH₃) with carbon dioxide:

$2{\text{NH}}_3\left(aq\right)+{\text{ CO}}_2\left(aq\right)+{\text{ CH}}_4{\text{N}}_2\text{O}\left(aq\right)+{\text{ H}}_2\text{O}\left(l\right)$

An industrial synthesis of urea produces 87.5 kg of urea upon reaction of 68.2 kg of ammonia with 105 kg of carbon dioxide. Determine the limiting reactant, theoretical yield of urea, and percent yield for the reaction.
