During an experiment water was heated in a container covered with a glass lid. the following observations were recorded.
observation 1: water droplets form on the inside of the glass lid.
observation 2: bubbles rise as the water starts boiling. based on the observation, justify the type of change (physical or chemical) that took place.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
