calculate enthalpy of H for the reaction N2H4(l) + 2H2O(l) -> N2(g) + 4H2)(l)

calculate enthalpy of H for the reaction

N2H4(l) + 2H2O(l) -> N2(g) + 4H2)(l)

Given the reactions
N2H4(l) + O2(g) -> N2(g) + 2H2O(l) Enthalpy of H = -6.22.2 kJ

H2(g) + (1/2)O2(g) -> H2O(l) enthalpy of H = -285.8 kJ/mol

H2(g) + O2(g) -> H2O2(l) enthalpy of H = -187.8 kJ

Answer #2
You are defiantly right.
it is suppose to be 2H2O2(l) and 4H2O(l)

and the first equation is suppose to be -622.2 kJ/mol

actually they are all suppose to be kJ/mol, but that was a typo on the exercise.

For a final answer I got -818.2 kJ/mol

i used the first equation as is. then i used the second equation and multiplied it by two and then for the last equation i reversed it and also multiplied it by 2.
