The reaction of hydrogen with oxygen and fire to make water is really explosive. But the earth has a shitton of water , that must mean there was a shitton of hydrogen and oxygen gas before. Shouldn't the earth have been blown to smithereens by the reaction?

>> No.6113317

Yes it should. I don't know how it didn't, maybe God protected it.

>> No.6113321

water arrived onto the surface of the earth from meteor strikes, it didn't form on the earth itself

>>6113321
so you think it formed in space, froze then merged with rocks and stuff to make comets and then crashed into the earth?

This is pretty ironic.
Pure hydrogen is flammable as fuck.
Pure oxygen is flammable as fuck.
Put 'em together and you can put out a fire.

>>6113325
doesn't that make sense since it's like "the dual" of a flammable substance?

Does that work with other flammable gases?

Once it's burned, there's no more potential for burning, so yes it would smother a fire. Water is just hydrogen ash, and you can use ash to smother a fire.

I d-don't know the actual science behind it, I just like coming here.

Oh so that's why hydrogen cars emit water.

Sure, why not.

it's actually incredibly un-ironic.
flamable+flamable combust to form inert
why is that surprising?

Pure oxygen isn't actually flammable, but it makes things more flammable.

That's a matter of perspective. You could say oxygen burns in hydrogen.

Not unless you change what the word "burns" means.

thats how the core is so warm OP

Every car emits water. The chemical reaction for all combustion produces carbon and water.

>>6113325
Well, to be fair if the the fire is hot enough you're gonna make some explosions. The H2O ionizes into its gaseous components and then increases combustion, see magnesium fires and water.

before earth had oceans or any liveable conditions, it had a heavy, thick hydrogen and helium atmosphere. the hydrogen and helium washed away due to being able to escape earth's gravity. over time, the earth gained a CO2 and N2 atmosphere from outgassing. life developed after water was delivered via comets and started photosynthesis and thats where the O2 came from. also N2 dilutes O2 so it doesnt blow up

Pure oxygen is not flammable by itself.
