Question

Can you please give me some facts about nitrogen?

Answer 1

- It is an odorless, colorless, and mostly inert gas, and continues to be colorless and odorless at a liquid state. 
-Nitrogen is believed to be the seventh most abundant element in the universe.
-At normal pressure, nitrogen liquefies at 77 K (-195.79 °C) and freezes at 63 K (-210.01 °C).
-Liquid nitrogen boils at -195.8 degrees Celsius.
-Due to its volatility, it is a fairly rare element on Earth, remaining as a gas in the atmosphere.
-Scientists in the eighteenth century recognized that there was a component of air that did not support combustion, thus discovering nitrogen.
-In 1772, Daniel Rutherford discovered what he called "noxious air," air that didn't contain oxygen.
-Large scale nitrogen manufacturing takes place through liquefaction of air and the fractional distillation of the resulting liquid air.All living things contain nitrogen, mostly in amino acids, DNA, and RNA.
