question

The AM1 valence electronic energies of the atoms H\mathrm{H} and O\mathrm{O} are −11.396eV-11.396 \mathrm{eV} and −316.100eV-316.100 \mathrm{eV}, respectively. For H2O\mathrm{H}_2 \mathrm{O} at its AM1-calculated equilibrium geometry, the AM1 valence electronic energy (core-core repulsion omitted) is −493.358eV-493.358 \mathrm{eV} and the AM1 core-core repulsion energy is 144.796eV144.796 \mathrm{eV}. For H(g)\mathrm{H}(g) and O(g),ΔHf,298∘\mathrm{O}(g), \Delta H_{f, 298}^{\circ} values are 52.102 and 59.559kcal/mol59.559 \mathrm{kcal} / \mathrm{mol}, respectively. Find the AM1 prediction of ΔHf,298∘\Delta H_{f, 298}^{\circ} of H2O(g)\mathrm{H}_2 \mathrm{O}(g).
Plain-text mathematical notation (without MathML)
The AM1 valence electronic energies of the atoms H and O are −11.396eV and −316.100eV, respectively. For H₂O at its AM1-calculated equilibrium geometry, the AM1 valence electronic energy (core-core repulsion omitted) is −493.358eV and the AM1 core-core repulsion energy is 144.796eV. For H(g) and O(g),ΔH_(f,298)^(∘) values are 52.102 and 59.559kcal/mol, respectively. Find the AM1 prediction of ΔH_(f,298)^(∘) of H₂O(g).
