Using the equations N, (g) + O, (g) 2 NO (g) AH° = 180.6 kJ/mol
N, (g) + 3 H, (g) → 2 NH (9) AH° = -91.8 kJ/mol
2 H, (g) + 0, (g) → 2 H O (9) AH° = -483.7 kJ/mol
Determine the enthalpy (in kJ/mol) for the reaction
4 NH, (g) + 5 0, (g) → 4 NO (g) + 6 H,0 (g).

Pauling and lewis questioned the extreme definitions of bonds. they wondered if bonds might be described somewhere in between the two extremes (covalent and ionic). on the basis of experimental data, pauling confirmed that bonds could be ionic, covalent, and for those, in between, exhibit a degree of ionic character. he theorized that the major factor was how strongly the atoms in the bond attracted the electrons. pauling called this factor - the tendency of an atom to attract electrons in a bond.

How can you use chemical equations to predict the products of the reaction you can carry out?

Particles vibrate in a rigid structure and do not move relative to their neighbors.
