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?

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
