WebIron combusts in oxygen to form various iron oxides, mainly iron (III) oxide: 4 Fe (s) + 3 O2 (g) ==> 2 Fe2O3 (s) Iron in its usual bulk solid form will only burn when in pure oxygen with when a great deal of heat is supplied. This is what a cutting torch does. WebFeb 23, 2024 · The heat causes the iron to react with the oxygen surrounding the steel wool. This reaction creates the spark that we see and the release of heat that heats up the next iron molecules, thus causing chain reactions through the steel wool. The very bright light is because of the extreme heat.
