Enthalpies of Formation (Section)
The following is known as the thermite reaction:
2 Al(s) + Fe2O3(s)→ Al2O3(s) + 2 Fe(s)
This highly exothermic reaction is used for welding massive units, such as propellers for large ships. Using standard enthalpies of formation in Appendix C, calculate ΔH° for this reaction.
