It also serves as an oxidation reaction catalyst. In enhanced oil recovery, high pressure nitrogen is used to force crude oil that would otherwise not be recovered out of oil wells.    For example, oxygen sensors are sometimes used as a safety precaution when working with liquid nitrogen to alert workers of gas spills into a confined space. Nitrogen is an essential constituent of all vegetable and animal proteins which are vital for life processes. Nitrogen gas properties. The method of preparation of nitrogen and N 2 (Dinitrogen) is the same. They have the same physical and chemical properties as well as uses. It is effective in getting rid of unstable organic compounds in liquids. Uses of Nitrogen in Industries. The molecular form of nitrogen is referred to as N 2. Like any other state of matter exhibit both physical and chemical properties, Nitrogen gas also tends to exhibit the same. How is nitrogen used? Nitrogen has just one type of atom, so it is an element. The melting and the boiling point of Nitrogen gas are −209.86 °C (−345.8 °F) and 195.8 °C (−320.4 °F), respectively. Many industries use it to destroy toxic liquids and vapors in industrial tools. Structure of Nitrogen Properties of Nitrogen Gas. Liquid nitrogen readily evaporates to form gaseous nitrogen, and hence the precautions associated with gaseous nitrogen also apply to liquid nitrogen. Nitrogen is used to produce ammonia (Haber process) and fertilizers, vital for current food production methods. Check out these amazing nitrogen facts and learn more about the gas that makes up most of the air you breathe. The element is used in controlling pollution. Nitrogen Facts. Therefore, the atomic weight of Nitrogen is 7, while its atomic weight is 14.0067. It is also used to manufacture nitric acid (Ostwald process). As nitrogen dioxide, the element is vital in the industrial sector. Nitrogen is a fascinating element with many unique properties and uses related to fertilizer, dynamite, medical anesthetic and even car racing. Nitrogen gas is a colorless, odorless and tasteless gas that makes up 78 % of the atmosphere volume, it does not help in burning, it is non-flammable and it will not support combustion.
