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.

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.

Most of the nitrogen has been around... Scientists think since the beginning of... When Earth even had an atmosphere.

Its atmosphere is largely molecular nitrogen, like you are breathing here in this room, except that its atmosphere is suffused with simple organic materials like methane and propane and ethane.

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

By interfering with the carbon, nitrogen, water, and phosphorus cycles, human activity changes the atmosphere, oceans, waterways, forests, and ice sheets, and diminishes biodiversity.

Photolysis in the atmosphere Photolysis also occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary pollutants such as peroxyacyl nitrates.

We inject our own aerosols into the atmosphere, and we have trace gases, and not just carbon dioxide it's methane, ozone, oxides of sulfur and nitrogen.

It's nitrogen narcosis.

Nitrogen oxides (NOx)

It's nitrogen narcosis.

Let's see, we have one nitrogen here, we have one nitrogen there.

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.

Air is a mixture of oxygen and nitrogen, 20 percent oxygen, 80 percent nitrogen.

Bacteria are vital in recycling nutrients, with many of the stages in nutrient cycles dependent on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction.

A trace gas is a gas which makes up less than 1 by volume of the Earth's atmosphere, and it includes all gases except nitrogen (78.1 ) and oxygen (20.9 ).

The nitrogen has two problems.

It decays into nitrogen 14.

And how much nitrogen 14?

That's nitrogen with three hydrogens.

Zeolite it's not new zeolite removes nitrogen from air and nitrogen is 78 percent of air.

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.

Now you know, you've got nitrogen in your protein, we've got nitrogen in our DNA so nitrogen is part of us, part of, you know, many many living things.

Yields 4 moles of nitrogen monoxide.

Nitrogen has 14 atomic mass units.

Gradual loss of nitrogen, calcium, phosphorus.

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

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

Venera 4 provided the first chemical analysis of the Venusian atmosphere, showing it to be primarily carbon dioxide with a few percent of nitrogen and below one percent of oxygen and water vapors.

In chemistry, N represents the element nitrogen.

If you did, it would be nitrogen,

And that reaction produces some nitrogen monoxide.

What happens to all that nitrogen there?

Now we have our own liquid nitrogen.

But nitrogen gas specifically is actually N2.

You have much more nitrogen hanging out.

There's no nitrogen and it turns sterile.
