This is not a correct chemical equation. Each chemical compound is different from the others and cannot be equated in this way.

Fe2O3 is iron (III) oxide, Fe is elemental iron, FeCl2 is iron (II) chloride, Fe(OH)2 is iron (II) hydroxide, Fe(OH)3 is iron (III) hydroxide, and Fe2(SO4)3 is iron (III) sulfate. Each of these compounds has its own unique chemical composition and properties.
