Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature.

In either case, the aim is to produce nitrogen gas, rather than nitrogen oxides.

Lighter isotopes of nitrogen are preferred in the reaction, leaving the heavier nitrogen isotopes in the residual matter.

Nitrogen fixation by cyanobacteria in coral reefs can fix twice the amount of nitrogen than on land around 1.8 kg of nitrogen is fixed per hectare per day.

It's nitrogen narcosis.

In chemistry, N represents the element nitrogen.

The RMS velocities of diatomic nitrogen and oxygen are very similar and thus no change occurs in the ratio of oxygen to nitrogen.

Nitric oxide, or nitrogen oxide, also known as nitrogen monoxide, is a molecule with the chemical formula NO.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

Ammonia nitrogen was removed via nitrification denitrification up to 40 when nitrogen loading rates were of 0.18 kg N (m3 d).

However, an excited state zwitterionic isomer exists in which H is transferred from the oxygen (giving an oxygen anion) to the nitrogen (giving a protonated nitrogen cation).

Nitrogen, phosphorus, and sulfur are also needed in relatively large quantities.

Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen.

Like other beans, it hosts bacteria that fix nitrogen in the soil.

The Dearman engine differs from former nitrogen engine designs in that the nitrogen is heated by combining it with the heat exchange fluid inside the cylinder of the engine.

) This is typically done with chlorine and nitrogen gas.

An analogous process for organic nitrogen compounds is deamination.

Now the one thing that I forgot to mention, is that to obviate the problem of the nitrogen narcosis all of those blue dots in our body you remove the nitrogen and you replace it with helium.

Auroras and the atmosphere Auroras result from emissions of photons in the Earth's upper atmosphere, above , from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state.

Even in rich countries, it usually isn t the rich who die in natural disasters.

In the '60s already, through the green revolution and the Haber Bosch process of fixing nitrogen from the atmosphere you know, human's today take out more nitrogen from the atmosphere than the whole biosphere does naturally as a whole.

The amount of nitrogen and sulfur circulating through the Earth system has doubled.

Biological nitrogen fixation (BNF) could help to improve soil fertility and crop productivity.

Bioethanol has been shown to reduce nitrogen oxide emissions by 50 per cent

To this effect, the United Kingdom adopted the Ammonium Nitrate Materials (High Nitrogen Content) Safety Regulations in 2003.

Both are rich in diamonds.

The nitrogen just sort of floats around in our blood and tissues, and that's all fine, that's how we're designed.

This design lowers the emissions of both nitrogen oxides (NO x ) and carbon dioxide (CO2).

Oranges are rich in vitamin C.

China is rich in natural resources.

A characterization of these fibers was given as well as hypotheses for their growth in a nitrogen atmosphere at low pressures.

Frank Caro process and Ostwald process dominated the industrial fixation of nitrogen until the discovery of the Haber process in 1909.

With liquid nitrogen, a blister may form at the treatment site, but it will slough off in two to four weeks.

And if we see the nitrogen dioxide and oxygen, I think we have the perfect E.T.

He observed that mixtures of alkali metal oxides and carbon react at high temperatures with nitrogen.

The rich and only the rich built what they have.

This election is particularly rich in lessons.

Indeed, Paraguay is rich in development potential.

Ammonium perchlorate can also be used, as it decomposes mainly into chlorine, nitrogen, and oxygen when heated.

I'm rich.

You're rich.

Feeling Rich

The excited molecular nitrogen (atomic nitrogen being rare due to high stability of the N2 molecule) plays its role here as well, as it can transfer energy by collision to an oxygen atom, which then radiates it away at the green wavelength.

CAMBRIDGE Almost all rich countries are rich because they exploit technological progress.

And the problem, the limitation of diving with air is all those dots in your body all the nitrogen and all the oxygen.
