How much energy is given out during the reaction: 8 C5H18N2 + 20 O2 =32 H2O + 5 C8H16 + 8 N2O. Does it give more than 42.4 MJ/Kg. Is it more efficient than gasoline? Is the equation correct?Or is C8H18N2 + O2 = H2O + C8H16 + N2O more efficient. Can you find the energy output of both this reaction? Does this reactions release less toxicants. Can you explain everything.
