example of a dipole-dipole bond.
(answers may vary)
what is O-H / N-H / F-H ?
300
consider the reaction: N2(g) + 3 H2(g) 
2 NH3(g)
where ΔH = -92.22 kJ and ΔS = -198.75 J/K
is the reaction spontaneous at 298.15 K and 427.15 K?
@ 298.15 K --> ΔG = -32.96 kJ , yes spontaneous
@427.15 K --> ΔG = -7.324 kJ, yes spontaneous

the reasoning behind dispersion forces.
what is an instant in time where the electrons in one atom are all pushed to one side, creating an instantaneous dipole, which, in turn, causes the electrons in a different atom to all push to one side creating an induced dipole that is then attracted to the partial positive in the instantaneous dipole?
