Question about storable liquid oxidizers

[Bill Dunaway]

I was wondering about the relative merits of various liquid oxidizer. The US has favored nitrogen tetra oxide. How does it compare to nitric acid derivatives or hydrogen peroxide in terms of efficiency and toxic levels?

Bill,
I'm no chemist, but if N04 has four atoms of oxygen in each molecule, than that is twice as much as in the same volume of H2O2, and in fact four times as much available oxygen, as only one in the H2O2 can be used for oxidation. Look up Avogadro's Number - it applies to gases, but ?also liquids?

That's not necessarily true, because these liquids won't have the same molar density; that is, they won't have the same number of molecules per unit volume. Given equal temperatures and pressures, the molar density will be the same for gases, but not for liquids. I don't know much about liquid oxidizers, so I can't say which is better, but I thought I should throw that out there.
