A fuel/oxidant system consisting of

\mathrm{N}, \mathrm{N}

-dimethylhydrazine \left(\mathrm{CH}_3\right)_2 \mathrm{NNH}_2

and

\mathrm{N}_2 \mathrm{O}_4

(both liquids) is used in space vehicle propulsion. The liquid components are mixed stoichiometrically so that

\mathrm{N}_2, \mathrm{CO}_2

and

\mathrm{H}_2 \mathrm{O}

are the only products. If all gases are under the same reaction conditions, number of moles of gases produced from 1 mole of \left(\mathrm{CH}_3\right)_2 \mathrm{NNH}_2

is
