Iron (II) sulfide or ferrous sulfide (Br.E. sulphide) is one of a family of chemical compounds and minerals with the approximate formula Fe S. Iron sulfides are often iron-deficient non-stoichiometric. All are black, water-insoluble solids. FeS can be obtained by the heating of …

The Mellah of Fez (Arabic: ملاح) is the historic Jewish quarter (Mellah) of Fez, Morocco. It is located in Fes el-Jdid, the part of Fez which contains the Royal Palace (Dar al-Makhzen), and is believed to date from the mid-15th century.

Iron (II) sulfate (British English: iron (II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 · x H 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known. The hydrated form is used medically to treat or prevent iron deficiency, and also for industrial applications.

Jun 28, 2024 · Iron (II) sulfide, represented chemically as FeS, is a distinct compound where iron and sulfur atoms bond in a one-to-one ratio. This compound is integral to the field of chemistry, showcasing the fascinating ways in which different elements can combine to form materials with unique properties.

Iron sulfide is the chemical compound FeS, a black solid. It is made of iron and sulfide ions. FeS has iron in its +2 oxidation state. It reacts with acids such as hydrochloric acid to make hydrogen sulfide gas. In plural, "iron sulfides" may refer to a range …

Jan 30, 2023 · Hydroxide salts of transition metals and Al 3+ are insoluble. Thus, Fe (OH) 3, Al (OH) 3, Co (OH) 2 are not soluble. Most sulfides of transition metals are highly insoluble, including CdS, FeS, ZnS, and Ag 2 S. Arsenic, antimony, bismuth, and lead sulfides are also insoluble. Carbonates are frequently insoluble.

Iron(II) sulfide is a chemical compound with the formula FeS. In practice, iron sulfides are often non-stoichiometric. Powdered iron sulfide is pyrophoric. FeS can be obtained by reacting iron and sulfur. S 8 (s) + 8Fe (s) → 8FeS (s)
