Which statement best describes the dipoles that cause London dispersion forces? A. The dipoles contain a hydrogen atom.
B. The dipoles are instantaneous and temporary.
C. The dipoles are permanent separations of charges.
D. The dipoles are caused by a difference in electronegativity.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
