1) Use the standard enthalpies of formation to determine ΔH°_rxn  for the reaction.

4 NH_(3 (g))+5 O_(2 (g))→4 NO_( (g))+6 H_2 O_( (g))

2) The thermite reaction, in which powdered aluminum reacts with iron oxide, is highly exothermic.

2 Al_( (s))+Fe_2 O_(3 (s))→Al_2 O_(3 (s))+2 Fe_( (s))

Use standard enthalpies of formation to find ΔH°_rxn  for the thermite reaction.
