Depending on your wool, you … 網頁The reason that a block of iron or steel doesn’t burn is that it’s really hard to get the oxygen molecules close enough to the iron to react. Compare that to highly combustible materials, like wood. Wood actually lets out combustible gases as it burns, which react immediately with oxygen. Iron doesn’t do this.
網頁The reaction of the rusting of iron involves an increase in the oxidation state of iron, accompanied by a loss of electrons. Rust is mostly made up of two different oxides of iron that vary in the oxidation state of the iron atom. These oxides are: Iron (II) oxide or ferrous oxide.
