A) 1st step: get each grams of H2 and Fe3O4and convert to moles 2nd step: get each moles of H2 and Fe3O4 and do mole to mole ratio to convert to moles of one of the product (either Fe or H2O). 3rd step: The least amount of moles of product is the limiting reactant, and therefore, the answer for A. B) Convert the limiting reactant of the product to grams C) 1st step: Convert the limiting reactant moles to the excess reactant moles by mole to mole ratio. 2nd step: Convert excess reactant moles to grams. 3rd step: Subtract excess reactant grams from the grams the excess reactant started with.
