You may need to download version 2.0 now from the Chrome Web Store. I know Oxygen has an oxidation number of 2- which makes the total number 8- but it's not divisible by 3 to find out Fe. 3D Visualization of the Iron Oxidation State in FeO/Fe 3 O 4 Core–Shell Nanocubes from Electron Energy Loss Tomography Pau Torruella †, Raúl Arenal ‡ , Francisco de la Peña * … It's a trick question. =), For the best answers, search on this site https://shorturl.im/awT6r. Each O is -2 for a total of -8, so oxidation number for Fe would have to be 8/3. Unless the oxygen atoms are bonded to fluorine or in a peroxide, these atoms will always have an... See full answer below. It occurs in nature as the mineral magnetite. Oxidation experiments were carried out in a continuous stream of air for period of 30 min. Want to see this answer and more? Fe 3 O 4 contains Fe atoms of both +2 and +3 oxidation number. Is this a mistake ? Oxidation state of Fe in Fe3O4 is asked Jan 7, 2019 in Chemistry by Hiresh (82.9k points) redox reactions aiims neet 0 votes 1 answer Oxidation state of Fe in Fe3O4 is … The valence is 5.
