At liftoff, a space shuttle uses a solid mixture of ammonium  perchlorate and aluminum powder to obtain great thrust from the volume change of solid to gas. In the presence of a catalyst, the mixture forms solid aluminum oxide and aluminum trichloride and gaseous water and nitrogen monoxide.
(c) What is the change in volume from this reaction? (d of NH₄CLO₄ = 1.95g/cc , AL = 2.70 g/cc , AL₂O₃ = 3.97 g/cc and ALCL₃ = 2.44 g/cc assume o1 mol of gas occupies 22.4.l)
