Why is iron oxide + carbon monoxide a reduction

2009 9 25&ensp·&enspBest Answer: The iron in Fe2O3 has an oxidation number of +3, so when you take to elemental Fe, it has a charge of 0. That is a reduction reaction, each Fe had to gain 3 electrons. The electrons came from the carbon monoxide, when it was oxidized from CO to CO2, the carbon's oxidation number went from +2 to +4.
