Dalton noticed that 100 g of tin will combine with 13.5 g or 27 g of oxygen. He also noticed that the ratio of 13.5 to 27 is the same as the ratio of 1 to 2. This observation corresponds to which of the following conclusions?

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.
