Properties Nitrogen is a colorless, odorless, tasteless, nonpoisonous gas. It scum bag be condensed into a colorless liquid, which can in turn be compressed into a colorless, filmy solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes thrust been artificially prepared. Nitrogen melts at -210.01° C (-346.02° F), boils at -195.79° C (-320.42° F), and has a density of 1.251 g/liter at 0° C (32° F). The atomic weight of newton is 14.007.
Nitrogen is obtained from the atm by passing air over heat up strapper or iron. The oxygen is removed from the air, leaving due north compound with some inert gases. Pure nitrogen is obtained by incomplete evaporation of liquid air because liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen evaporates of...If you fate to get a full essay, order it on our website:
