The coating you see on a corroded iron object that has been left in moist soil is black iron oxide (Fe3)4). The substance can also be made in the laboratory by the reaction between iron and steam, according to the following equation. 3Fe+4H2O->Fe3O4+4H2
When 25.0g os H2O reacts with 65g of Fe, which is the limiting reactant? How much excess reactant is used when the reaction is completed? What mass in grams of black iron oxide is produced?
