Use bond energies to calculate ?Hrxn for the
reaction.
2H2(g)+O2(g)?2H2O(g)
Note: The answer is NOT 442 kJ or 442kJ/mol
It gave me this hint when I got the answer wrong: The bond
energies of H?H, O=O, and H?O are provided in the introduction. To
determine the enthalpy of this reaction, sum all of the bond
energies for the reactants (accounting for stoichiometric ratios as
is), and subtract the bond energies for the product. Note how many
bonds are in each...
