Zn(s)+2hcl(aq)= zncl2(aq)+h2(g)
0.306 moles of hcl are required to consume all of the zn in the reaction mixture..
what is the volume of the solution that will deliver the required amount of the concentration is 2.5 m in hcl? what volume is required to prepare this solution from a concentrated (18m)?

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
