Problem
A particulate representation depicts 18 individual Fe atoms and 12 O2 molecules before reaction. After the reaction is complete, 9 formula units of Fe2O3 are present and no reactants remain. Determine the smallest whole-number coefficients needed to balance the chemical equation for the formation of Fe2O3 from Fe and O2.
