Question

f standard enthalpies of formation for H2O (g) -242. CH4 (g) -75. And CO2 (g) I'd -111 kj mol-1 respectively. Determine the heat of the reaction of the following reaction? CH4 (g) + 2H2O -->CO2 (g) +4H2.​

Answer 1

Explanation:

Hydrazine and 1,1-dimethylhydrazine both react spontaneously with O2 and can be used as rocket fuels.

N2H4(l)+O2(g)⟶N2(g)+2H2O(g)

N2H2(CH3)2(l)+4O2(g)⟶2CO2(g)+4H2O(g)+N2(g)

The molar enthalpy of formation of N2H4(l) is +50.6 kJ/mol, and that of N2H2(CH3)2(l) is +48.9kJ/mol. Use these values, with other ΔfH∘ values , to decide whether the reactio
