What is FeS2 called?
What is FeS2 called?
The mineral pyrite (), or iron pyrite, also known as fool’s gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Despite being nicknamed fool’s gold, pyrite is sometimes found in association with small quantities of gold.
What chemical formula is FeS2?
FeS2
Ferrous disulfide/Formula
What happens when pyrite is mixed with water?
Sulfate released from decomposing pyrite combines with water, producing sulfuric acid, leading to acid mine drainage. An example of acid rock drainage caused by pyrite is the 2015 Gold King Mine waste water spill.
Is pyrite soluble in water?
The mineral pyrite, or iron pyrite, is iron sulfide, FeS2…
Why is FeS2 called fool’s gold?
Pyrite is called “Fool’s Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does.
Is FeS2 soluble in water?
Iron(II) sulfide or ferrous sulfide (Br. E. sulphide) is one of a family chemical compounds and minerals with the approximate formula FeS….Iron(II) sulfide.

Why is pyrite bad?
Pyrite, often known as fool’s gold, can be one of the most dangerous minerals. Composed of iron and sulphur, pyrite can contaminate ground water and streams via tailings waste from mines. Oxidation of pyrite releases toxic metals and metalloids such as arsenic, a poisonous element.

Which is the correct formula for Fe + 2?
[Fe+2]. [S-2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Iron (II) sulfide or ferrous sulfide (Br.E. sulphide) is one of a family chemical compounds and minerals with the approximate formula Fe S. Iron sulfides are often iron-deficient non-stoichiometric.
What kind of sulfide is 99.9% Fes?
Ferrous monosulfide; Ferrous sulfide; Ferrous sulfide (FeS); Iron monosulfide. Ferrous monosulfide. Ferrous sulfide (FeS) Iron monosulfide (FeS) Iron (II) sulfide, 99.9%, (trace metal basis), -100 mesh. a FeS cluster. HSDB 5803. a FeS center.
How can Fes be obtained from iron and sulfur?
FeS can be obtained by the heating of iron and sulfur: Fe + S → FeS. FeS adopts the nickel arsenide structure, featuring octahedral Fe centers and trigonal prismatic sulfide sites.
What happens when hydrogen sulfide is mixed with water?
Some of the hydrogen sulfide will react with metal ions in the water or solid to produce iron or 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.
