Calculate the enthalpy change (AH) in kJ for the
following reaction.
2Al(s) + Fe2O3(s) → 2Fe(...
Calculate the enthalpy change (AH) in kJ for the
following reaction.
2Al(s) + Fe2O3(s) → 2Fe(s) + Al2O3(s)
Use the enthalpy changes for the combustion of
aluminum and iron:
2Al(s) + O2(g) →→ Al2O3(s)
Al,,() AH = -1669.8 kJ
2Fe(s) + O2(g) → Fe, c(s) AH = -824.2 kJ
