Your role playing game party of high fantasy warriors arrives at a blacksmith to get new weapons forged. The blacksmith forges a longsword with 1.74 kg of iron at 1371 °C. which was cooled down in 8.5 L of water initially at 40 °C. What is the final temperature of the iron longsword when it reaches thermodynamic equilibrium? The specific heat capacity of iron is 0.444 J/g °C.

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
