The most important manganese ore is pyrolusite (MnO2).

Lithium sulfide is the inorganic compound with the formula Li2S.

Several oxides of manganese, for example manganese dioxide, are abundant in nature, and owing to their color, these oxides have been used as pigments since the Stone Age.

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

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

Before year 2000, more than 1.6 million tonnes have been used of those alloys with a content of 1 manganese, this amount would need 16,000 tonnes of manganese.

The brown color of ceramic is sometimes based on manganese compounds.

Compared to 1953, levels of manganese in air have dropped.

In the nickel and copper deposits, the platinum group metals occur as sulfides (i.e.

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

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

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

Germanium disulfide or Germanium(IV) sulfide is the inorganic compound with the formula GeS2.

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.

In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions.

Color ranges from yellow to dark brown or black, the latter being due to the presence of manganese.

Binary compounds with other chalcogens are also known, such as the disulfide (), diselenide (), and the monosulfide (GeS), selenide (GeSe), and telluride (GeTe).

The oxidation state 5 can be obtained if manganese dioxide is dissolved in molten sodium nitrite.

Because of the use in glassmaking, manganese dioxide was available to alchemists, the first chemists, and was used for experiments.

In 2005, a study suggested a possible link between manganese inhalation and central nervous system toxicity in rats.

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

Carbon steel contains 2.0 carbon or less, with small amounts of manganese, sulfur, phosphorus, and silicon.

These compounds consist of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese, and so on.

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

List of producing countries This is a list of countries by manganese in 2006, mostly based on British Geological Survey accessed in June 2008.

Manganese(II) chloride describes a series of compounds with the formula MnCl2(H2O)x, where the value of x can be 0, 2, or 4.

Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon.

With the exception of available manganese iron ratio data, the contractors did not agree to authorize the Authority to make use of nodule abundance and metal content data from their contract areas.

The hydrate is unusual in that it forms two different structures (both based on Mn(H2O)2F4 ), which have space groups P21 c and P21 a.

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.

Another option is the use of chemical depilatories, which work by breaking the disulfide bonds that link the protein chains that give hair its strength.

There are more stages involved here than I've got time to tell you about, but basically we drive through the space, we populate it with environmental variables sulphide, halide, things like that.

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.

Steel is an alloy of iron and carbon containing less than 2 per cent of carbon and 1 per cent of manganese (and small amounts of silicon, phosphorous, sulphur and oxygen).

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.

About 80 of the known world manganese resources are found in South Africa other important manganese deposits are in Ukraine, Australia, India, China, Gabon and Brazil.

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.

According to some estimates, Kazakhstan has the second largest uranium, chromium, lead, and zinc reserves, the third largest manganese reserves, the fifth largest copper reserves, and ranks in the top ten for coal, iron, and gold.

Eighteen radioisotopes have been characterized, with the most stable being 53Mn with a half life of 3.7 million years, 54Mn with a half life of 312.3 days, and 52Mn with a half life of 5.591 days.

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.

Alloyed steels, which are sometimes also called special steels and may be considered specialty products, contain small portions of alloying elements such as chromium, cobalt, manganese, molybdenum, nickel, niobium, silicon, tungsten or vanadium.

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.
