Q. 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) + CO2(aq) → CH4N2O(aq) + H2O(l) In an industrial synthesis of urea, a chemist combines 129.6 kg of ammonia with 211.4 kg of carbon dioxide and obtains 161.5 kg of urea. Determine the limiting reactant. Express your answer as a chemical formula.
