Industrially, nitrogen is prepard by the fractional distillation of liquid air, Air from which carbon(IV)oxide has been removed, is liquefied by subjecting it to successive compression and cooling processes.
Iron is used as a catalyst in the Haber process, which is the industrial method for producing ammonia from nitrogen and hydrogen gases. The presence of iron catalyst helps to increase the rate of the reaction and improve the yield of ammonia.

Nitrogen and carbon dioxide are two industrial gases that are not harmful. Nitrogen is often used for inerting and blanketing applications, while carbon dioxide is commonly used in food and beverage production and refrigeration.
When nitrogen is fixed, it is changed into ammonia, which can then be used by plants to make proteins and other essential compounds. This process is mainly carried out by nitrogen-fixing bacteria in the soil or by industrial processes.
Media used for industrial fermentation can include glucose, sucrose, starch, molasses, and other carbon sources. Nitrogen sources such as ammonium sulfate, yeast extract, and peptones are commonly used as well. In addition, minerals, vitamins, and sometimes growth factors may be added to support microbial growth and productivity during the fermentation process.
The Dumas method is used to determine the nitrogen content in organic compounds. It involves combustion of the sample at high temperatures to convert the nitrogen into nitrogen gas, which is then collected and measured. By knowing the mass of the sample and the amount of nitrogen gas produced, the nitrogen content of the original compound can be calculated.
Nitrogen is commonly used to make fertilizers, explosives, and industrial chemicals. Liquid nitrogen is also used in cryogenics for cooling and preserving biological samples.

Yes, liquid nitrogen can be used to cut steel. When liquid nitrogen is applied to steel, it causes the steel to become extremely brittle and easier to break or cut. This method is often used in industrial applications for precision cutting of steel components.
Nitrogen is used in fertilizers to help plants grow, in the production of ammonia for various industrial processes, as a component in explosives, and in the manufacturing of electronics.

This is a very convenient method but its use is restricted.This method is suitable for estimating nitrogen in those organic compounds in which nitrogen is linked to carbon and hydrogen. The method is not used in the case of nitro, azo and azoxy compounds. The method is extensively used for estimated nitrogen in food, fertilizers and agricultural products.Principle:- the method is based on the fact that when the nitrogenous compound is heated with concentrated sulphuric acid in presence of copper sulphate, the nitrogen present in the compound is quantitatively converted to ammonium sulphate. The ammonium sulphate so formed is decomposed with excess of alkali and the ammonia evolved is estimated volumetrically. The percentage of nitrogen is then calculated from the amount of ammonia.
Soda lime is used to detect the presence of nitrogen in nitrogen-containing compounds through a process called the Kjeldahl method. It is used to absorb the evolved ammonia gas during the digestion of the sample, which is then released by heating the soda lime and can be quantitatively determined. This method helps in determining the nitrogen content in organic compounds.
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
Nitrogen and carbon dioxide are two industrial gases that are not harmful. Nitrogen is often used for inerting and blanketing applications, while carbon dioxide is commonly used in food and beverage production and refrigeration.
The purification method used in the preparation of iodoform in the experiment is recrystallization. This process involves dissolving the impure iodoform in a solvent at an elevated temperature and then slowly cooling the solution to allow pure iodoform crystals to form and separate from the impurities.
When nitrogen is fixed, it is changed into ammonia, which can then be used by plants to make proteins and other essential compounds. This process is mainly carried out by nitrogen-fixing bacteria in the soil or by industrial processes.
