You are asked to bring the ph of 0.500l of 0.550 m nh4cl to 7.00. which of the following solutions would you use: 12.0 m hcl or 12.0 m nh3? how many drops (1 drop 0.05 ml ) of this solution would you use? the answer to part one is 12.0 m nh3 but how do you answer the second part? you

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.
