Dimethylhydrazine, (CH3)2NNH2, was used as a fuel for the Apollo Lunar Descent Module, with N2O4 being used as the oxidant. The products of the reaction are H2O, N2, and CO2.
i) Write a balanced chemical equation for the combustion reaction.
ii) If 150 kg of (CH3)2NNH2 react with 460 kg of N2O4, what is the theoretical yield of N2?
iii) If a 30 kg yield of N2 gas represents a 68% yield, what mass of N2O4 would have been used up in the reaction?
