Two of the isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 3 10227 kg and 21.59 3 10227 kg, respectively. These two isotopes are singly ionized (1e), each given a speed of 6.667 3 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic fi eld is 0.8500 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.

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.
