2. a. b. At 25° C, Kc = 0.90 for the reaction H₂O(g) + Cl₂O(g) → 2HOCI(g) Calculate the concentration of all species at equilibrium when 1.0 mole of gaseous water and 2.0 moles of gaseous Cl₂O are placed in a 1.0 L vessel. (8 marks) Ksp for lead(II) chloride is 2.4 × 10¯*. Determine the mass of lead chloride that will dissolve in 250 mL of water. (2.5 marks) i. ii. Determine whether a precipitate results when 100 mL of 0.020 M Pb(NO3)2 is mixed with 100 mL of 0.020 M NaCl. (2.5 marks) 2. a. b.
