It's filled with this toxic gas, hydrogen sulfide.

Carbon dioxide plus hydrogen gas yields methane plus water.

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.

Hydrox, a gas mixture of hydrogen and oxygen, was used as a breathing gas in very deep diving.

Cold seeps are areas where cold, oxygen depleted fluids, which may be rich in hydrogen sulphide or methane, flow upwards through cracks in the ocean floor.

This box can be used to specify the molar mass of the gas, e. g. 2 for Hydrogen gas.

Hydrogen has to be extracted from Natural Gas, coal or water, which uses more energy than we get from the Hydrogen.

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

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

And this gas was called illuminating gas, and it was both a toxic and explosive mixture of carbon monoxide and hydrogen.

Like natural gas, hydrogen can be used as a car fuel with engine modifications.

22. In Kuwait and Saudi Arabia the ground level concentrations of nitrogen dioxide, nitrogen oxides, carbon monoxide, hydrogen sulphide and ozone did not exceed the local and recognized standards.

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

Hydrogen, hydrogen, hydrogen..

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

Such areas are often associated with high concentrations of methane or hydrogen sulphide and include dysaerobic ocean basins, hydrothermal vents, cold seeps and the remains of large dead animals, such as whales, described below.

So it's carbon, hydrogen, hydrogen, hydrogen.

So you're going to have a hydrogen there, a hydrogen over there, a hydrogen over here... a hydrogen over here, a hydrogen over there... a hydrogen over here, almost done, hydrogen there and then a hydrogen there.

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.

You have a hydrogen hydrogen bond.

UNIDO also supports the introduction of sources such as solar, hydrogen and small scale hydropower from which greenhouse gas emissions are minimal.

So hydrogen, this hydrogen, might have one.

So there's a bond right here, and this is why hydrogen is a diatomic molecular gas, and this is why iodine is the same.

So hydrogen has a covalent bond with another hydrogen.

He has a free electron over there hydrogen, hydrogen.

Hydrogen pocket!

Hydrogen iodide.

Hydrogen Iodide.

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.

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.

The Hydrogen Solution

Renders hydrogen bonds

Because it's hydrogen.

This is hydrogen.

This hydrogen disassociates.

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

So it grabs some hydrogen and becomes hydrogen flouride, or hydrofluoric acid.

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.

Liquid hydrogen or slush hydrogen may be used, as in the Space Shuttle.

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

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