The black oxide of iron, Fe3O4, occurs in nature as the mineral magnetite. This substance can also be made in the laboratory by the reaction between red-hot iron and steam according to the equation:

3Fe(s) + 4H2O(g) - Fe3O4(s) + 4H2(8)

a. When15.0 g of Fe is mixed with 50.0 g of H, which is the limiting reagent?

b. Which is the excess reactant, and what mass in grams of excess reactant remains when the reaction is completed?

c. If 17.5 g of Fe3O4 is produced, what is the percent yield?

H2O = 18.0 g/mol
Fe = 55.8 g/mol
Fe3O4 = 231.5 g/mol
