# Iron(III) oxide reacts with carbon monoxide according to the
following equation:
Fe2O3 (s) + CO (g)
® Fe (s) + CO2
(g)
1- Balance the above equation.
2- A reaction mixture contains 10.51 g of
Fe2O3 and 11.95 g of CO. Once the reaction
has occurred as completely as possible, how many grams of excess
reactant will remain? (MM of Fe2O3 =
159.69 g/mol) (show your work for
credit)
3- Determine the oxidation number of the element in bold in each
of the following species:
Fe2O3
ii.
CO
iii. CO2
