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.
Iron (II) sulfide, also popular as iron sulfide or ferrous sulfide, is an inorganic, water-insoluble compound represented by the chemical formula FeS [1, 2]. In IUPAC nomenclature, it is called sulfanylideneiron [1]. It naturally occurs as the minerals troilite and pyrrhotite [3].
27 de abr. de 2024 · Iron (II) sulfide, or FeS, is made by directly combining iron and sulfur. To do this safely in a lab, mix 7 grams of iron powder with 4 grams of sulfur in a porcelain crucible. This mixture is based on the chemical reaction ensuring the right balance between the iron and sulfur. Fe + S → FeS.

9 de jul. de 2016 · BRIAN M. Jul 9, 2016. The molecule formula is F e2S3. Explanation: The molecule iron (III) sulfide is an ionic molecule between the metal Iron and the non-metal sulfur. In an ionic molecule the formula is determined by balancing the charges on the ions. For this case the roman numeral (III) tells us the iron has a charge of +3 or F e+3.
