The payload of a rocket includes fuel and oxygen for combustion of the fuel. Reactions 1 and 2 describe the combustion of dimethylhydrazine and hydrogen, respectively.

Calculate the energy change for the below reaction in kJ per pound.

(CH3​)2​NNH2​(l)+4H2​O(g)=N2​(g)+4H2​O(g)+2CO2​(g)
ΔHrxn = -1694 KJ
Calculate the energy change for the below reaction in kJ per pound.
H2​(g)+1/2​O2​(g) = H2​O(g)

ΔHrxn​=−286kJ
