Question

Ammonium perchlorate mixed with powdered aluminium powers the space shuttle booster rockets: 2NH4ClO4 (g) + 2Al (s) => Al2O3 (s) + 2HCl (g) + 2NO(g) + 3H2O (g)

Given the following thermochemical data, how much heat would be released per gram of Al(s)?

The values of ∆H of reaction are as follows:
ΔHf (H2O(l)) = -285.1 kJ/mol-1
ΔHf (NO(g)) = 90.4 kJ/mol-1
ΔHf (HCl(g)) = -92.3 kJ/mol-1
ΔHf (Al2O3 (s)) = -1669.8 kJ/mol-1
ΔHf (NH4ClO4 (s)) = -290.6 kJ/mol-1
ΔHvap (H2O) = 44.1 kJ/mol-1
