When 4.00 g оf irоn (MM = 55.845 g/mоl) is reаcted with 4.00 g of wаter (MM = 18.02 g/mol) аccording to the chemical equation shown below: What is the limiting reactant? What mass of Fe3O4(s) (MM = 231.53 g/mol) is produced? How many grams of the excess reactant are left? If 4.75 g of Fe3O4(s) were obtained, what is the percent yield? Must show your work on scratch paper to receive credit. 3 Fe(s) + 4 H2O(l) → Fe3O4(s) + 4 H2(g)
