How do you explain the formula Fe3O4 using the ionic compound …
2017年8月2日 · I don't understand at all how the ionic bonding in $\\text{Fe}$$3$$\\text{O}$$4$ works. The oxygens all together have $4(–2e)=–8e$ net charge. But we cannot give the three irons equal positive charge...
Why iron reacts with steam to give Fe3O4 not Fe2O3?
2023年10月15日 · It should be obvious that The reduction of water by iron stops at FeX3OX4 F e X 3 O X 4. Above 900 K 900 K, it stops even at FeO F e O. Above 1700 K 1700 K, hydrogen reduces FeO F e O to iron. Note that the respective temperatures are related to equilibrium states. The open system with the flow of steam reactant and removal of hydrogen somewhat shifts …
