Nitrogen Gas - N2

NITROGEN GAS

Nitrogen makes up the major portion of the atmosphere (78.03% by volume, 75.5% by weight). Gaseous nitrogen is inert, colourless, odourless, tasteless, nontoxic, noncorrosive, and non-flammable. Nitrogen is inert and will not support combustion; however, it is not life supporting.

Nitrogen is inert except when heated to very high temperatures, where it combines with some of the more active metals, such as lithium and magnesium, to form nitrides. It will also combine with oxygen to form oxides of nitrogen and when combined with hydrogen in the presence of catalysts, will form ammonia.

Since gaseous nitrogen is inert,…
