Re: Burning hydrogen at high temperatures ::snip for length::
Yup, nitrogen and oxygen like to party together in various different ways. IIRC, nitrogen can happily form oxidation states from -3 (ammonia) right up to +5 (dinitrogen pentoxide). For most of these gases, you will not be laughing if you breathe them.
Nitrogen dioxide, for example, will react readily with water to form nitric and nitrous acid. Get any amount of that in your lungs, and there's no coming back.
