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

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

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

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

Other compounds detected in volcanic gases are oxygen (meteoric), hydrogen chloride, hydrogen fluoride, hydrogen bromide, nitrogen oxide (NOx), sulfur hexafluoride, carbonyl sulfide, and organic compounds.

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

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.

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.

Acid gases carbon dioxide (CO2), hydrogen sulfide (H2S) and mercaptans such as methanethiol (CH3SH) and ethanethiol (C2H5SH).

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

Peter Ward Yeah, every single cell in us can produce minute quantities of hydrogen sulfide in great crises.

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.

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

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.

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

You're in an accident. You've got two choices you're going to die, or you're going to take the hydrogen sulfide and, say, 75 percent of you is saved, mentally.

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.

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.

Air samples taken from inside an unopened sarcophagus through a drilled hole showed high levels of ammonia, formaldehyde and hydrogen sulfide these gases are all toxic, but are easily detected by their strong odours.

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.

So, these are the thought leaders in trauma medicine all over the world saying this is true, so it seems that exposure to hydrogen sulfide decreases damage that you receive from being exposed to otherwise lethal low oxygen.

Asteroid strikes get all the coverage, but Medea Hypothesis author Peter Ward argues that most of Earth's mass extinctions were caused by lowly bacteria. The culprit, a poison called hydrogen sulfide, may have an interesting application in medicine.

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.

It turns purple from the presence of numerous microbes which have to have sunlight and have to have hydrogen sulfide, and we can detect their presence today we can see them but we can also detect their presence in the past.

Am I understanding you right, that what you're saying here is that we have in our own bodies a biochemical response to hydrogen sulfide that in your mind proves that there have been past mass extinctions due to climate change?

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

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?

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.

Lithium sulfide is the inorganic compound with the formula Li2S.

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.

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.

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. Everest, and they can sit there for hours, and there's no problem.

And in an enormous 40 page paper in German he says, at one point my wife is German and she translated it for me and at one point he says, ganz widerlich Geruch, an absolutely repulsive smell, which is good. Reminiscent of hydrogen sulfide.

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.

Instead, they should provide the automobile industry with incentives to develop alternative technologies that rely on bio mass fuel, ethylene, hydrogen, and even natural gas during a transition period.

It can also be produced directly using the Girdler sulfide process.

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

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.

The Hydrogen Solution

And this company, the first thing it did was make a liquid formulation of hydrogen sulfide an injectable form that we could put in and send it out to physician scientists all over the world who work on models of critical care medicine, and the results are incredibly positive.

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.

The Great Hydrogen Hope

This led Lee Kump, and others from Penn State and my group, to propose what I call the Kump Hypothesis many of the mass extinctions were caused by lowering oxygen, by high CO2. And the worst effect of global warming, it turns out hydrogen sulfide being produced out of the oceans.
