This chapter’s introduction mentioned the following reaction as one chemical reaction used to power the lunar module in space. Calculate the mass of dinitrogen tetroxide, N₂O₄, required to generate 7632 J of energy (the approximate kinetic energy of the lunar module moving at a velocity of 1 m/s). The thermochemical equation is
