To the other person that said there is not enough left over H to make
water with the O in the air, sorry, incorrect. Water and heat are two

balance the equation. No, I don't! g

I do remember enough to balance a simple reaction like this. All you need
to do is tell me which hydrocarbon you want to combust! I don't know the
formula for avgas. :-)


I took a real quick look at work today - somewheres near 16 to 25H, 8
to12C. Gasoline tends to the low end of the range, Jet fuel at the high end.
Both, of course, vary so you can pretty much pick what you want.

Well, someone already beat me to the punch with an algebraic solution
that will handle any HC compound. :-)
