Using this equation, answer the following questions: 3 Fe + 4 H2O Fe3O4 + 4 H2
a. Theoretically, how many grams of Fe3O4 can be obtained if 16.8 g of Fe was used?
b. Theoretically, how many grams of Fe3O4 can be obtained if 10 g of H2O was used?
c. Using part a and b, what is the limiting reactant and what is the excess reactant?
d. If 20.1 g of Fe3O4 was recovered in the experiment, what is the percent yield and percent error?
