Chemistry experiment 35 - Iron burning in oxygen

In pure oxygen, iron becomes very flammable.

has anyone's science teacher sent them here?

WOW! GREAT! Thank you for your work.

fuckin awesome dude you're perfect

Why the steel wool is heated Can we do this experiment without heating it

[@blackbirdgaming8147]

Pradheepan Mayyil No you can’t. What’s happening here is the steel wool is heated so that it is almost burning, and then it reacts with the pure oxygen to form oxides which produces heat and light.

[@beddawafa5769]

what is the chemical equations of this reaction?

[@squadontheway9615]

Iron + oxygen ---> Triferric tetroxide 3Fe + 2 O2 ---> Fe3O4

amazing but why you dont talk you will have more subscribers

[@PeterPete]

It's steel wool burning in oxygen, not iron.

[@TuanLe-md5tv]

its iron wool

[@PeterPete]

@@TuanLe-md5tv it's not iron wool because the wool product contains carbon!! without the carbon content there is no metal!!

I wonder how much oxygen is necessary. Could you provide adequate oxygen just with ambient air and a blower? Would there be enough with a plug in home oxygen concentrator? The notion of iron as fuel is very attractive: extremely safe and stable, common and accessible, and no harmful emissions at all. Could one run a steam engine off of scrap iron and a blower fan?

+wread42 i am guessing... nosomeone did make a combustion engine that ran on magnesium though, i saw it here

[@plainlake]

+wread42 Iron is not really that common though, using it as fuel seems kind of a waste.

[@wread42]

+plainlake Not that common as compared to what? The earth is 32% iron. By mass there is nothing more common. I suspect all the iron delayed development of an oxygen atmosphere by 500 million years.

[@plainlake]

wread42 Common in terms of realistically minable ore... I did not think It was needed for me to specifically exclude the planetary core. :) And even then you would have to use energy to make it into metallic iron first. You might be on to something about oxygen getting trapped in reactions before it could stay in the atmosphere though. It is called the "boring billion" of years between the points where cyanobacteria first started to produce free oxygen as a waste product, and to the point where there was enough for animal cells to use the free oxygen. And as far as I know I dont think there is a comprehensive answer to why it did not happen sooner.
