Concept: Balancing Chemical Reactions

Problem: 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) + H2O(g)Fe3O4(s) + CO(g) → Fe(s) + CO2(g)

FREE Expert Solution
  • For the reaction, Fe3O4(s) + H2(g) → Fe(s) + H2O(g), balance O first, then H and lastly Fe. Usually, the monoatomic or diatomic atoms are the ones we balanced lastly.
  • Balance O (4 on both sides)

Fe3O4(s) + H2(g) → Fe(s) + 4H2O(g)

  • Balance H (4 on both sides)

Fe3O4(s) + 8 H2(g) → Fe(s) + 4H2O(g)
