A student creates a mixture of water and washing soda weighing 10 g and a mixture of water and epsom salts weighing 15 grams. He knows that when he mixes the two
substances a chemical change will occur. According to the law of conservation of mass,
what should the weight of the products be after he mixes them?

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
