Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO42 ).

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

Oxidation of hydrogen sulfide produces elemental sulfur (S8), oxidation state 0.

Now, hydrogen sulfide is curiously present in us.

Dissimilative sulfur reduction in which elemental sulfur can be reduced to hydrogen sulfide.

Shipwrecks are perfectly preserved.

In purple sulfur bacteria, hydrogen sulfide (H2S) is oxidized to sulfur (S).

And so, we wanted to find out might we be able to use hydrogen sulfide in the presence of cold, and we wanted to see whether we could reproduce this skier in a mammal.

In fact, in chemical accidents, hydrogen sulfide is known to if you breathe too much of it, you collapse to the ground, you appear dead, but if you were brought out into room air, you can be reanimated without harm, if they do that quickly.

So, it was interesting for us when we applied hydrogen sulfide to a mouse when it was also cold because what happened is the core temperature of the mouse got cold.

We also found out that we could subject animals to otherwise lethal blood loss, and we could save them if we gave them hydrogen sulfide.

In one model of heart attack, animals given hydrogen sulfide showed a 70 percent reduction in heart damage compared to those who got the standard of care that you and I would receive if we were to have a heart attack here today.

And I should say that the concentrations of hydrogen sulfide required to get this benefit are low, incredibly low.

And so we thought, like in a game of musical chairs, might we be able to give a person some hydrogen sulfide, and might it be able to occupy that place

There is tremendous amounts of hydrogen sulfide coming into this cave from volcanic sources and from the breakdown of evaporite minerals below the carbonates in which this cave is formed and it is a completely hostile environment for us.

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

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth. Shipwrecks are perfectly preserved.

If you give mice hydrogen sulfide, you can lower their demand for oxygen, and you can put them into oxygen concentrations that are as low as 5,000 feet above the top of Mt.

And what you're seeing here is a cloud of densely packed, hydrogen sulfide rich water coming out of a volcanic axis on the sea floor.

They often use some of several laboratory methods for diagnosis of bad breath Halimeter a portable sulfide monitor used to test for levels of sulfur emissions (to be specific, hydrogen sulfide) in the mouth air.

One thing those people did out there was take this technology of hydrogen sulfide, which is this start up company that's burning venture capital very quickly, and they fused it with another company that sells another toxic gas that's more toxic than hydrogen sulfide, and they give it to newborn babies who would otherwise die from a failure to be able to oxygenate their tissues properly.

So, it was interesting for us when we applied hydrogen sulfide to a mouse when it was also cold because what happened is the core temperature of the mouse got cold.

Chlorium Oxide 13 Lead sulfide 3

And so, we wanted to find out might we be able to use hydrogen sulfide in the presence of cold, and we wanted to see whether we could reproduce this skier in a mammal.

There is tremendous amounts of hydrogen sulfide coming into this cave from volcanic sources and from the breakdown of evaporite minerals below the carbonates in which this cave is formed and it is a completely hostile environment for us.

I told you hydrogen sulfide is in us.

So hydrogen has a covalent bond with another hydrogen.

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

So hydrogen, this hydrogen, might have one.

Lithium sulfide is the inorganic compound with the formula Li2S.

And so we thought, like in a game of musical chairs, might we be able to give a person some hydrogen sulfide, and might it be able to occupy that place like in a game of musical chairs where oxygen might bind?

Sulfur water is a condition where the running water contains a high amount of hydrogen sulfide gas that escapes into the air when the plumbing line is opened, giving a distinct rotten egg smell.

In one model of heart attack, animals given hydrogen sulfide showed a 70 percent reduction in heart damage compared to those who got the standard of care that you and I would receive if we were to have a heart attack here today.

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.

Yttrium(III) sulfide (Y2S3) is an inorganic chemical compound.

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

of your hydrogen concentration

Let's say you have hydrogen.

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.

The Great Hydrogen Hope

Hydrogen, hydrogen, hydrogen..

And oxygen gained hydrogens.

Hydrogen is very small.
