The reuseable booster rocket of the U.S space shuttle emplot a mixture of aluminum and ammonium perchlorate for fuel. A possible equation for this reaction is:
3Al(s)+ 3NH4ClO4(s) --> Al2O3(s) + AlCl3(s)+3NO3(g)+ H2O(g)
What mass of NH4ClO4 should be used in the fuel mixture for every kilogram of Al.
