  1. Iron sulfide. Formula: FeS. Molecular weight: 87.910. IUPAC Standard InChI: InChI=1S/Fe.S. Copy Sheet of paper on top of another sheet. IUPAC Standard InChIKey: MBMLMWLHJBBADN-UHFFFAOYSA-N. Copy Sheet of paper on top of another sheet. CAS Registry Number: 1317-96-0. Chemical structure:

  2. The formula is AlPO 4, and the name of the compound is aluminum phosphate. Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. To get 6+, we need three iron(II) ions, and to get 6−, we need two phosphate ions. The proper formula is Fe 3 (PO 4) 2, and the compound's name is iron(II) phosphate.

  3. 10 de ago. de 2023 · The gram formula unit mass for iron (III) sulfide is 207.87, and the gram atomic mass of iron is 55.847. Therefore, the fraction by mass of iron in iron (III) sulfide is 2(55.847) ...

  4. When iron sulfide is exposed to oxygen it reacts rapidly, releasing large amounts of heat. This exothermic reaction can be an ignition source for any oil or gas that is present. The oxygen in the air reacts with exposed iron sulfide and eventually reaches a temperature that can cause hydrocarbons to ignite. Of primary importance is preventing ...

  5. To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound. In this video, we'll walk through this process for the ionic compound calcium bromide. Created by Sal Khan.

  6. 10 de ago. de 2023 · The formula for Ferrous sulfide (iron-II sulfide) is FeS. The iron-II ion has a valence of +2, and since sulfur has a valence of -2, it only takes one of each to make a valence-neutral molecule.

  7. Compute Mass of Each Element. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in Fe2 (S)3: Molar Mass (g/mol) Fe (Iron) 2 × 55.845 = 111.69. S (Sulphur/Sulfur) 3 × 32.065 = 96.195. 4.
