Hydrocarbon motors now-a-days depend on nitrogen to be the bulk of their working fluid and to dilute the flame and limit its temperature. This leads to nitrogen oxide formation.

In the Haber process, nitrogen and hydrogen react together under these conditions:

There are 1 Nitrogen and 3 Hydrogens on the right side ; Hydrogen …

In natural waters, one of the most important sources of organic nitrogen is proteins and their hydrolysis products.

Elements with their electron shells mostly, but not completely, filled are, in order of electronegativity: fluorine, oxygen, chlorine, and nitrogen. In that upper right , of largely filled electron shells, phosphorus and sulfur also reside. Carbon and hydrogen have their valence shells half filled. With the exception of fluorine, those elements listed above provide virtually all of the human body’s atoms. The body also contains metals, particularly sodium, magnesium, calcium, and iron, which “donate” electrons and make key chemical reactions possible. Fluorine forms the smallest negatively charged ions known to science and wrecks organic molecules for reasons . Organisms do not use fluorine, except for some .

nitrogen + hydrogen  ammonia

Ammonia is a raw material used in the manufacture of fertilisers, explosives and cleaning fluids. It is produced using a reaction between nitrogen and hydrogen called the Haber process. Production costs of making ammonia are based on factors including the rate of reaction, and the cost of energy, labour, raw materials and equipment.

Power-generating internal boron combustion also doesn't lend itself to burning and emitting nitrogen. Boron fuel cells may be , but, unlike the case with hydrogen, would have no edge in cleanliness over boron combustors. Cars in which boron fuel simply burns will be true zero emission vehicles.

In the reaction of nitrogen gas n2 with hydrogen - Match Problems

That should do it. Do a check to be sure: You have 2 nitrogen atoms on the left and 2 nitrogen atoms on the right. You have 6 hydrogen atoms on the left and 6 hydrogen atoms on the right.

Balanced Chemical Equation: Definition & Examples - …

The equation is balanced. You can read the equation this way: 1 nitrogen molecule reacts with 3 hydrogen molecules to yield 2 ammonia molecules.

Balancing chemical equations - Chemical Formula

Nitrogen and phosphorus are the most vital elements for life after carbon, hydrogen, and oxygen. In its pure state in nature, nitrogen, like hydrogen and oxygen, is a diatomic molecule. Hydrogen in nature is single-bonded to itself, oxygen is double-bonded, and nitrogen is triple-bonded. Because of that , nitrogen is quite unreactive and prefers to stay bonded to itself. In nature, nitrogen will not significantly react with other substances unless the temperature () is very high. Most nitrogen compounds in nature are created when the nitrogen and oxygen that comprise more than 99% of Earth’s atmosphere react under lightning’s influence to create nitric oxide, which then reacts with oxygen to form nitrogen dioxide, and atmospheric water combines with that to make nitrous and nitric acids, which then fall to Earth’s surface in precipitation. Certain kinds of bacteria “fix” the nitrogen from the acidic rain into biological systems. Also, some bacteria can fix nitrogen directly from atmospheric nitrogen, but it is an that uses the energy in eight ATP molecules to fix each atom of nitrogen. For the earliest life on Earth, nitrogen would have been essential, and , where .
