Thermochemistry

Liquidized hydrazine, N2H4, and liquid 1, 1-dimethylhydrazine, N2H2(CH3)2, both react spontaneously with O2 and can be used as rocket fuel. Reaction A: N2H4(l) + O2(g) = N2(g) + 2H20(l)Reaction B: N2H2(CH3)2(l) + 4O2(g) = N2(g) + 4H2O(l) + 2CO2(g)a. Use the given information to calculate deltaHrxn for reactions A and B. Please show your work.CompoundStandard enthalpy of formation deltaHformationN2H4(l)50.6kJ.molN2H2(CH3)2(l)48.9kJ.molO2(g)0kJ/molH2O(l)-285.8kJ/molCO2(g)-393.5kJ/molN2(g)0kJ/molb. If you have 5.00kg of each liquid rocket fuel, which will provide more energy? Show the calculation of energy for each compound.
