Need help on the chemical workings of n2o hi all, first post here, and i've confused myself. (i feel like a moron, i swear i knew the answer to this a week ago, a friend has asked me now and i cant remember)
i realize that n2o is not a flamable gas, yet when you heat it up to around 570 degrees, it splits into nitrogen and oxygen, the oxygen is used in combustion with the extra fuel, etc. etc.
my question is, what keeps the gas from seperating if it was sprayed into a gasoline fire? wouldnt the oxygen seperate and everything go kaboom?

Re: Need help on the chemical workings of n2o Here is a formula that I have been working on.
N20 + LS1 = HP
I don't think that cylinder pressure contributes to the split in the way that was referenced above. Cylinder pressure contributes to the cylinder temperature via Boyels (sp?) law: PV/T. If you decrease the volume, pressure and TEMPERATURE increase. It is the temperature that splits the N20 molecule.
If you do spray N20 at a fire, yes it will act as an accellerator (oxidizer) and actual cause the fire to burn faster.
If you get a hot enough fire, you can do this to anything. Metal fires (zinc and magnesium are common ones) you cannot use water to put out because the water molecule sprayed over the very very very very very very hot fire will actual split into H2 and O2. H2 is very explosive on its own, and O2 acts as an accellerator.
So yes, if have a hot enough fire and you SPRAY the N20 over it, it will accellerate the fire.

Re: Need help on the chemical workings of n2o Happy to spray it at a fire? Well if you were spraying it nywhere it'd probably dissapate so much before it got there it wouldnt do much. But yeah it will accel. fire growth, same with oxygen tanks, with the fire warning thing.
Re: Need help on the chemical workings of n2o Nogo is right on the money....You spray N2O at a fire producing similar temps as in the combustion chamber it WILL accelerate the fire. Problem is a campfire will not produce the same effect as a combustion chamber at 1100 degrees and 10:1 compression. The same goes with Nitromethane, its a lot less dangerous than gasoline under atmospheric conditions. Put it under 14:1 compression @ 1100 degrees, feed it at several times the rate of gas.....7000 horsepower. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
