55 Ammonia is not the only possible fertilizer. Others include urea, which can be produced by the reaction: C O 2 ( g ) + 2 N H 3 ( g ) → C O ( N H 2 ) 2 ( s ) + H 2 O ( g ) A scientist has 75 g of dry ice to provide the carbon dioxide. If 4.50 L of ammonia at 15 ∘ C and a pressure of 1.4 atm is added, which reactant is limiting? What mass of urea will form?
