Question: The space shuttle's expendable booster engines derive their power from solid reactants: 6NH4+ ClO-4 (s) + 10Al(s) 3N2(g) + 9H2O(g) + 5Al2O3(s) + 6HCI(g)

The space shuttle's expendable booster engines derive their power from solid reactants:
6NH4+ ClO-4 (s) + 10Al(s) → 3N2(g) + 9H2O(g)
+ 5Al2O3(s) + 6HCI(g)
(a) Find the oxidation numbers of the elements N, Cl, and Al in reactants and products. Which reactants act as reducing agents and which act as oxidants?
(b) The heat of reaction is - 9334 kJ for every 10 mol of Al consumed. Express this as heat released per gram of total reactants.
