Answer: FeO is the formula unit for a compound made from and oxygen. If a substance exists as discrete molecules (as with atoms that are chemically bonded together) then the chemical formula is the molecular formula, and the formula weight is the molecular weight. For both questions, show your work or explain how you determined the formulas by giving specific … So, this empirical formula What is the empirical formula of a compound containing 60% sulphur and 40% oxygen? Empirical Formula: A single unit of a chemical compound contains a certain number of each constituent atom (element). The proportion is 1:1. The ionic bond between ions results from the electrostatic attraction of opposite charges. No, oxide is just an oxygen ion. When an element is reactive, it means that it will readily react with many other substances. In this case, it tells you that there is an Hydrogen atom for each Oxygen atom.
