Nitrogen fixation is a chemical process by which molecular dinitrogen ( N. 2) is converted into ammonia ( NH. 3 ). [ 1] It occurs both biologically and abiologically in chemical industries. Biological nitrogen fixation or diazotrophy is catalyzed by enzymes called nitrogenases. [ 2]
For a citation to appear in a footnote, it needs to be enclosed in "ref" tags. You can add these by typing <ref> at the front of the citation and </ref> at the end. . Alternatively you may notice above the edit box there is a row of "markup" formatting buttons which include a <ref></ref> button to the right—if you highlight your whole citation and then click this markup button, it will ...
Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide ( NTO ), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.
Nitrogen trichloride, also known as trichloramine, is the chemical compound with the formula NCl3. This yellow, oily, and explosive liquid is most commonly encountered as a product of chemical reactions between ammonia -derivatives and chlorine (for example, in swimming pools ).

Nitrogen dioxide is a chemical compound with the formula NO2. One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas. It is a paramagnetic, bent molecule with C 2v point group symmetry. Industrially, NO2 is an intermediate in the synthesis of nitric acid, millions of tons of which are produced each year, primarily for the ...
Human impact on the nitrogen cycle is diverse. Agricultural and industrial nitrogen (N) inputs to the environment currently exceed inputs from natural N fixation. [ 1] As a consequence of anthropogenic inputs, the global nitrogen cycle (Fig. 1) has been significantly altered over the past century. Global atmospheric nitrous oxide (N 2 O) mole ...
