Web3Fe(s) + 4H2O(l) = 1Fe3O4(s) + 4H2(g) In any balanced chemical equation, if the coefficient of any reactant or product is one, then it is not required to write the numeral 1, and the coefficient can be omitted. Hence, the equation 3Fe+4H2O→1Fe3O4+4H2 is written as 3Fe+4H2O→Fe3O4+4H2 HINT: Element Fe = 1 atom in reactants, 3 atoms in products … WebMethod 2: oxidative process The amount of Fe3+ was calculated by the difference between FeCl2 4H2O (Aldrich, P99 wt.% pure, 25.48 g in 150 ml H2O) was the total amount of Fe (determined by ICP) and the total amount used as a source of Fe2+ ions and (Fe2+,Fe3+)-HA was synthesized, of Fe2+ (determined by UV–VIS).
