The unbalanced chemical equation for the reaction between iron III oxide Fe2O3 and carbon monoxide CO producing iron Fe and carbon dioxide CO2 is:Fe2O3 + CO Fe + CO2To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. First, balance the iron Fe atoms:2Fe2O3 + CO 4Fe + CO2Next, balance the carbon C atoms:2Fe2O3 + 3CO 4Fe + 3CO2Finally, balance the oxygen O atoms:2Fe2O3 + 3CO 4Fe + 3CO2The balanced chemical equation is:2Fe2O3 + 3CO 4Fe + 3CO2
