8.0 g of iron is reacted with 8.0 g of water according to the chemical equation shown below.Which one of the following statements is FALSE? 3 Fe(s)+ 4 H₂O(l)→ Fe₃O₄(s)+ 4 H₂(g)

To determine which reactant is limiting, we need to convert each reactant to the same product. The balanced equation tells us that for every 3 moles of Fe, we need 4 moles of H2O. Therefore, the number of moles of H2O present can produce only (8 g / 18 g/mol) * (3/4) = 1.5 moles of FeS13O4. On the other hand, the 8 g of Fe present can produce (8 g / 56 g/mol) = 0.143 moles of FeS13O4. Therefore, Fe is the limiting reactant and H2O is in excess. This means that statement D is false.
