burn by themselves - no oxygen required! This is because the combined chemicals, when energized, "reduce," or change in ionic state by reacting with each other, as opposed to an outside oxidant. The most commonly used monopropellant is hydrazine (N2H4), a chemical which is characterized as "strongly reducing". |
