Urea, also called carbamide (because it is a diamide of carbonic acid), is an organic compound with chemical formula CO(NH2)2. This amide has two amino groups (–NH2) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. Urea serves an important role in the cellular metabolism of nitrogen ...

Ammonia is a colourless gas with a characteristically pungent smell.It is lighter than air, its density being 0.589 times that of air.It is easily liquefied due to the strong hydrogen bonding between molecules. Gaseous ammonia turns to a colourless liquid, which boils at −33.1 C (−27.58 F), and freezes to colourless crystals at −77.7 C (−107.86 F).
