Calculation: A) Simple distillation of Impure water:
1 - Volume of coloured water = 70.0 mL
2
- Volume of distilled water = 33.2 mL
3 - Recovery % = | (2) / (1) | x 100
%
B) Fractional distillation of a mixture of acetone and
water:
- Volume of the Mixture = 70.0 mL
2- Volume of distilled liquid (acetone = 29.8 mL
3 - Recovery % = | (2) / (1) 1 x 100=. %

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.
