The mechanism involves oxidation of the selenol of a selenocysteine residue by hydrogen peroxide.

For example, if you have hydrogen gas, it's a diatomic molecule, because hydrogen bonds with itself in the gaseous state, plus iodine gas, I2.

That implies that the pressure of hydrogen gas is 1 bar and the activity of hydrogen ions in the solution is unity.

Up to 11.5 by weight absorption of hydrogen has been achieved.

Carbon dioxide plus hydrogen gas yields methane plus water.

Glutathione peroxidase 1 (GPx1) is the most abundant version, found in the cytoplasm of nearly all mammalian tissues, whose preferred substrate is hydrogen peroxide.

So there's a bunch of hydrogen molecules around, and some of these iodine gas molecules around.

Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.

At this depth, the temperature is above the critical temperature, which for hydrogen is only 33 K (see hydrogen).

Hydroxyquinoline was used as a stabilizer of hydrogen peroxide in a rocket fuel oxidizer (T Stoff) for the German Messerschmitt Me 163 Komet in World War 2.

This hydrogen is then taken up by methanogens and converted to methane via methanogenesis.

We have to go in with protective suits and breathing gear, and 30 parts per million of H2S will kill you.

Desulfurization in which organic molecules containing sulfur can be desulfurized, producing hydrogen sulfide gas (H2S, oxidation state 2).

Five years from now, this is what I hope happens to me I'm taken back to the boat, I'm given a gas mask 80 parts per million hydrogen sulfide.

So hydrogen has a covalent bond with another hydrogen.

Gas

Gas.

Gas?

So people really care about the concentration of hydrogen of your hydrogen ions.

So hydrogen, this hydrogen, might have one.

That it is negative shows that the reaction, if it were to proceed, would be exothermic that is, it is enthalpically more stable than hydrogen gas and carbon.

Hydrogen stations Hydrogen stations which are not situated near a hydrogen pipeline get supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production.

The hydrogen economy is a proposed system of delivering energy using hydrogen.

of your hydrogen concentration

Let's say you have hydrogen.

In 1915 he joined the Lookout Oil and Refining Company in Tennessee and was responsible for the installation of electrolytic cells for the production of hydrogen which was used in the hydrogenation of vegetable oils.

Dehydrogenation is a chemical reaction that involves the removal of hydrogen from a molecule.

There is a need to expand and deepen the community of scientists and engineers who work on energy issues, for instance within the disciplines of physics, chemistry, biotechnology and the social and economic sciences.

This is molecular hydrogen has two hydrogens and we have two moles of this.

I'll write nitrous oxide, it's N2O, this is laughing gas.

You have some oxygen gas or a diatomic oxygen molecule.

Gas, North Sea

Send another pipe down! Right now! It's a gas pocket!

The Great Hydrogen Hope

Hydrogen, hydrogen, hydrogen..

And oxygen gained hydrogens.

Hydrogen is very small.

So let's say if you have hydrogen.

So this is hydrogen.

losing hydrogens here.

It's between two isotopes of hydrogen, two kinds of hydrogen deuterium, which is heavy hydrogen, which you can get from seawater, and tritium which is super heavy hydrogen.

As a result, the plant s three active reactors suffered near meltdowns, leading to a buildup of hydrogen gas, a series of explosions and fires, and leakage of radioactive material into the atmosphere.

Liquid hydrogen (LH2 or LH2) is the liquid state of the element hydrogen.

Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.
