Mass a small wad of steel wool on a pyrex watch glass. Record the mass on your data sheet. Holding a Bunsen burner at the base, carefully direct a flame at the top of the steel wool until it glows brightly for five minutes. Do not heat the watch glass from the bottom. Be careful not to lose any of the material from the watch glass. Allow the materials to cool and re-mass the watch glass and product. Feº a steel Burn wad of wool (Feº) in O, Feº Fe2O3 a Burn wad of steel wool (Feº) in O, a Burn wad of steel wool (Feº) in o, A a Burn wad of steel wool (Fe°) in o, Bum a wad of steel wool (Fe) in o, Fezo, Burn wad of steel wool (Feº) in 0, Required:
