Iron sulfide or Iron sulphide can refer to a range of chemical compounds composed of iron and sulfur.
By increasing order of stability:
Iron(II) sulfide or ferrous sulfide (Br.E. sulphide) is a chemical compound with the formula FeS. In practice, iron sulfides are often iron-deficient non-stoichiometric. Powdered iron sulfide is pyrophoric (ignites spontaneously in air).
Iron sulfide reacts with hydrochloric acid, releasing the malodorous (rotten egg smell) and very toxic gas, hydrogen sulfide
FeS can be obtained by the heating of iron and sulfur:
As organic matter decays under low-oxygen (or hypoxic) conditions such as in swamps or dead zones of lakes and oceans, sulfate-reducing bacteria will use the sulfates present in the water to oxidize the organic matter, producing hydrogen sulfide as waste. Some of the hydrogen sulfide will react with metal ions in the water to produce metal sulfides, which are not water-soluble. These metal sulfides, such as iron(II) sulfide, are often black or brown, leading to the color of sludge.
Pyrrhotite is a waste product of the Desulfovibrio bacteria, a sulfate reducing bacteria.

The synthesis of iron (II) sulfide involves reacting 1 equivalent of sulfur with 1 equivalent of iron. The reaction is initiated by a hot glass stirring rod into it. It is an extremely exothermic reaction. This is an interesting reaction to use as a demonstration, but the product is useful. The Iron (II) sulfide, or FeS, can be reacted with hydrochloric acid to produce hydrogen sulfide gas. This is a very useful gas, but it is extremely toxic.
Reaction of iron with sulfur is initiated by heat and iron sulfide is formed.

A demonstration of how to produce iron sulfide. 2 grams of sulfur powder are thoroughly mixed with 3.5 grams of fine iron filings. The mixture is then placed in a test tube, which is gently plugged with ceramic wool. The mixture is then heated with a blue Bunsen flame. An exothermic reaction occurs and you can clearly see the reactants glowing as they chemically join together. Once the reaction has subsided, the test tube is allowed to cool. The iron sulfide produced is a hard brown solid, which should not be attracted to a magnet. Video produced by Tom's Photo Log: http://www.tomsphotolog.com

Why do we create explosionsandfire? Cyberbullying. Quick video showing a cool principle. While iron is not terribly reactive, increase the surface area enough and it will ignite as it reacts with oxygen in the air. Did you know that the words galactic and lactate are related? Makes sense when you think about it enough. Microscopic iron pieces are created through the thermal decomposition of iron(II) oxalate, which is created through the aqueous reaction of oxalic acid and iron(II) ions (I used iron(II) chloride if you really want to know).

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Like Earth, Mars has differentiated into a dense metallic core overlaid by less dense materials. Current models of its interior imply a core with a radius of about 1,794 ± 65 kilometers (1,115 ± 40 mi), consisting primarily of iron and nickel with about 16–17% sulfur. This iron(II) sulfide core is thought to be twice as rich in lighter elements than Ea...
Io /ˈaɪ.oʊ/ is the innermost of the four Galilean moons of the planet Jupiter and, with a diameter of 3,642 kilometres (2,263 mi), the fourth-largest moon in the Solar System. It was named after the mythological character Io, a priestess of Hera who became one of Zeus's lovers. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean satellites—Europa, Ganymede and Callisto. Several volcanoes produce plumes of sulfur and sulfur dioxide that climb as high as 500 km (300 mi) above the surface. Io's surface is also dotted with more than 100 mountains that have been uplifted by extensive compressi...
There is a long history of permanganate use in the oil and gas processing and petroleum refining industries. Permanganate oxidation chemistry is particularly effective for certain common impurities and pollutants that are found in oil and gas processing and refining. In particular, the destruction of hydrogen sulfide and organic sulfur compounds, and pyrophoric iron neutralization. Permanganate oxidation chemistry is also effective for pyrophoric iron removal, select metals adsorption, tetraethyl lead removal, organo-nitrogens and phenol, mercaptan/thiols, and cyanide oxidation.
The Silence of the Lambs is a 1991 American horror-thriller film directed by Jonathan Demme and starring Jodie Foster, Anthony Hopkins, and Scott Glenn. Adapted by Ted Tally from the 1988 novel of the same name by Thomas Harris. FBI trainee Clarice Starling is pulled from her training at the FBI Academy at Quantico, Virginia by Jack Crawford of the Bureau's Behavioral Science Unit. He assigns her to interview Hannibal Lecter, a former psychiatrist and incarcerated cannibalistic serial killer, whose insight might prove useful in the pursuit of a serial killer nicknamed "Buffalo Bill", who skins his female victims' corpses. Starling travels to the Baltimore State Hospital for the Criminally Insane, where she is led by Frederick Chilton to Lecter's solitary quarters. Although initially plea...
This chemistry video tutorial provides an introduction / basic overview explaining how to balance chemical equations such as combustion reactions, synthesis and decomposition reactions, single and double displacement reactions in addition to redox reactions under acidic and basic conditions. This video provides plenty of examples and practice problems that will help you to review for your next test or exam. Here is a list of equations covered in this video: 1.

“The most noteworthy are the pyroxenitic clasts, which occur in large, crystalline masses up to 8 cm --3 in-- in size in many hand specimens and are clearly of plutonic origin. They consist of xenomorphic-granular and tightly intergrown, coarse enstatite , with minor primary diopside , and accessory kamacite, taenite, titanoan troilite, oldhamite [CaS], and caswellsilverite. Xenomorphic plagioclase occurs in the interstices between enstatite grains and forms myrmekitic intergrowths with silica ----probably tridymite. Casanova, Keil, and Newsom studied the mineralogy and trace element composition of metal and metal nodules, up to 1.5 cm in size, in the Norton County aubrite and concluded that the metal did not undergo fractional crystallization in a core but, rather, is a fraction of the ...
https://www.iitutor.com Gases in the atmosphere The atmosphere contains low concentrations of a number of oxides of non-metallic elements including carbon dioxide, nitrogen dioxide, sulfur dioxide and sulfur trioxide. While these non-metal oxides exist in the atmosphere from natural sources, their concentrations have increased as a result of human activity, particularly since the onset of the Industrial Revolution. Some of these acidic oxides are responsible for acid rain, one of the most serious forms of air pollution affecting both natural and urban environments. Sulfur dioxide is an irritating gas with an acrid odour. It is quite soluble in water (9.4 g per 100 mL of water at a temperature of 25°C) and originates from many sources. It is an irritant of the respiratory system and contrib...

SETI Talks archive: http://seti.org/talks The alkaline hydrothermal theory for the emergence of life holds that the endergonic (thermodynamically uphill) reactions vital for life's origin and continued existence require free energy converters (nano-engines) fuelled by various disequilibria. The first two primary engines were i) a carbon fixation engine to generate the organic building blocks of life by reaction between hydrothermal CH4 and H2 with the CO2 and NO in atmosphere and ocean, ii) a proton pyrophosphatase engine exploiting the natural pH gradient between alkaline hydrothermal solution and acidulous ocean to drive biosynthesis by condensations of these same building blocks. To this end there occurred on the early Earth and other such rocky bodies, inorganic prebiotic molecules t...
