It has been calculated that the observed colored lines in a hydrogen line spectrum correspond to the relaxation of the electron from higher energy level down to the second energy level. Based on this information and how the wavelengths are ranked by energy, match each spectrum line wavelength to its corresponding transition.

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.
