Nitrogen
Nitrogen (N) has the atomic number 7 on the periodic table and is mostly found in the colorless, gaseous form. Nitrogen is also the most abundant element on the planet Earth.

How is the element nitrogen in nitrogen compounds in the soil released back into the air?
By the process denitrification. Some bacteria do that also human
What converts nitrogen in the nitrogen cycle?
okay heres the nitrogen cycle
nitrogen from atmosphere it taken in by
1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil)
2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere )
NITROGEN FROM SOIL to organisms
1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil
2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil
3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil
4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules
NITROGEN TO ATMOSPHERE
1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
What molecules of your body is nitrogen?
Nitrogen is in many compounds.They are in proteins,nucleic acids etc
This is called the nitrogen cycle.
Nitrogen is an inert gas and does not form compounds very easily, but it is a vital component in proteins needed for life on Earth. It is made to form compounds in two ways :-
- Using the energy on the inside of lightning strikes
- Using specialist bacteria called nitrogen fixing bacteria that are to be found in association with the roots of (particularly) leguminous plants.
Eventually however the organic compounds containing the nitrogen are broken down by decomposer organisms and the nitrogen get released again as an atmospheric gas.
In recent time humans have learned how to make nitrogen fertilizers, taking nitrogen out of the air and making compounds out of it using the energy of fossil fuels to do this. This unnatural excess of nitrogen added into the nitrogen cycle can and does upset the environment and is responsible for algal blooms in lakes etc.
Nitrogenase enzyme is used by nitrogen fixing bacteria to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen.Nitrogenase is the enzyme used by some organisms to fix atmospheric nitrogen gas (N2). It is the only known family of enzymes which accomplishes this process
Nitrogen was isolated by the British physician Daniel Rutherford in 1772, but was not recognized as an element until 1776 by the French chemist Antoine Laurent Lavoisier.
Condensation
Where does nitrogen from the atmosphere go before it enters the plants?
The nitrogen goes into the nodules of the plant.
Nitrogen is one of the components of air; thus, your clothing is exposed to it all the time. I don't think that having it liquid (and therefore supercold) would cause any additional effects - however, please note that splashing it on you is QUITE DANGEROUS, because it is extremely cold.
Why does nitrogen displace oxygen?
Like all gasses, nitrogen takes up space, so when nitrogen is put into a given area it pushed other gasses, including oxygen, out of the way.
Through warm and cold presses, yes
The main benefit of nitrogen filled tires is that the loss of tire pressure is slower, because the gas in the tire escapes more slowly than air does.
No: Rusting occurs by the combination of ferrous metals with oxygen from air or water, and nitrogen can not form the same compounds as oxygen does.
How does human factors influence or affect the nitrogen cycle?
Human factors influence or affect the nitrogen cycle through interacting physical, chemical and biological processes.
Is nitrogen gas a solvent or solute in a mixture?
Dissolved nitrogen in water is a solute; when nitrogen contain traces of another gas can be considered as a solvent.
How many liters does 1000 FTS of Liquid Nitrogen equal?
According to metal-wear, one liter of LN2 will make 22.8 standard cubic feet (scf) of gas. 1 scf equals approximately 1 FTS, the exact conversion depends on the ambient temperature and pressure. So 1000 FTS / 22.8 scf = 43.9 liters of liquid nitrogen.
When leak testing a low pressure centrifugal with nitrogen what is the maximum test pressure?
10 psig
Does alcohol contain nitrogen in its chemical structure?
Not necessarily. Alcohols have -OH as functional group.
Nitrogen is a diatomic elemental gas (79% in air) and rather insoluble in water.
As with most gasses, nitrogen is usually sold in metal canisters with a valve at the top (like the kind you see people filling baloons with Helium from). Alternately, liquid nitrogen is available for sale and comes in a sealed canister.
Nitrogen is an atom, which are too small to be alive. It's like asking if a single brick is a good house to live in.
Where is the earth's vast reservoir of nitrogen?
Earth's vast reservoir is in it's atmosphere which is roughly 79% nitrogen.
