Solid iron (III) oxide reacts with gaseous carbon monoxide to produce solid elemental iron and gaseous carbon dioxide. If 0.550g of iron (iii) oxide reacts with 0.250g of carbon monoxide, how much solid elemental iron will be produced (in grams). Determine which reagent is in excess, and how much will be left over (in grams).

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
