Hydrazine and 1,1-dimethylhydrazine both react spontaneously with O 2 and can be used as rocket fuels. The

Question:

Hydrazine and 1,1-dimethylhydrazine both react spontaneously with O₂ and can be used as rocket fuels. NH4(l) + O(g) N(g) + 2 HO(g) hydrazine NH(CH3)2() + 4 O(g) 2 CO(g) + 4HO(g) + N(g) 1,1-dimethylhydrazine

The molar enthalpy of formation of N₂H₄(ℓ) is +50.6 kJ/mol, and that of N₂H₂(CH₃)₂(ℓ) is +48.9 kJ/mol. Use these values, with other ∆_fH° values, to decide whether the reaction of hydrazine or 1,1-dimethylhydrazine with oxygen provides more energy per gram NASA Space vehicles, such as the Space Shuttle when it was still flying, use hydrazine as a fuel in control
