Problem: Urea (CH4N2O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH3) with carbon dioxide as follows: 2NH3(aq) + CO2(aq) → CH4N2O(aq) + H2O(l). In an industrial synthesis of urea, a chemist combines 133.0 kg of ammonia with 211.4 kg of carbon dioxide and obtains 173.0 kg of urea.Determine the limiting reactant.
