Find the standard molar enthalpy (AHº)for the reaction: Fe2O3(s) + 2 Als) – Al2O3(s) + 2 Fe(s)
Given
2 Als) + 3/2 O2(g) → Al2O3(s)
AH° = -1676 kJ
2 Fes) + 3/2 02() - Fe2O3(s)
AH° = -824 kJ
-852 kJ
+2500 kJ
+852 kJ
-2500 kJ

Aluminum–lithium (al-li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. a commercial aircraft skin material having a density of 2.47 g/cm3 is desired. compute the concentration of li (in wt%) that is required.
