The space shuttle carries about 7.25×10^4 kg of solid aluminum fuel, which is oxidized with ammonium perchlorate according to the following reaction: 10Al(s)+6NH4 ClO4 (s)--->4Al2 O3 (s)+ 2AlCl3 (s) + 12 H2 O(g)+ 3N2(g) The space shuttle also carries about 6.08×10^5 kg of oxygen (which reacts with hydrogen to form gaseous water). Part A: Assuming that aluminum and oxygen are the limiting reactants, determine the total energy produced by these fuels. Delta H for solid ammonium perchlorate is -295 kJ/ mol. Part B: Suppose that a future space shuttle was powered by matter-antimatter annihilation. The matter could be normal hydrogen (containing a proton and an electron) and the antimatter could be antihydrogen (containing an antiproton and a positron). What mass of antimatter would be required to produce the energy equivalent of the aluminum and oxygen fuel currently carried on the space shuttle?
