how is oxygen combustible but not flammable? If it feeds the fire isn’t it essentially the same thing?
In: Chemistry
If you lit a match in a room with 100% hydrogen, which is very flammable, the flame would go out instantly. That’s because the wood in the match needs oxygen to react with. And the hydrogen needs oxygen to react with (combust) so it would still not combust.
If you lit a match in a room with 100% oxygen, the flame would burn super bright until all the combustible material (match) was consumed, and then it would go out.
Oxygen supports the chemical reaction combustion but is not flammable itself. Hydrogen is very flammable but needs oxygen to support that reaction.
