[ MILICILES Iron oxide ores, commonly a mixture of FeO and Fe2O3, are given the general formula Fe3O4. They yield elemental iron when heated to a very high temperature with either carbon monoxide or elemental hydrogen. Balance the following equations for these processes: Fe3O4(s) + H2(g) → Fe(s) + H, 0(9) Fe3O4(s) + CO(9) ► Fe(s) + CO2(g) (Use the lowest possible coefficients for all reactions.)
