In an experiment 28.5g of metal was heated to 98.0c and then quickly transferred to 150.0g of water in a calorimeter. the initial temperature of the water was 20.5c amd the final temperature after the addition of the metal was 32.5c assume the calorimeter behaves ideally and does not absorb or release heat.

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
