For the preparation of bao2, we first prepare bacl2 by this reaction [baco3+hcl=bacl2++co2+h2o]after product the (bacl2) then we reacion the bacl2 with h2o2 to product the bao2why we do not use the bacl2 when we have in lab, we preparea fresh bacl2 to prepare bao2? ?

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
