Question 9 For a precipitation reaction to be useful in a gravimetric analysis, the product of the reaction must be insoluble. (A) True B) False Question 10 A) 0.0083 Analysis of the gases in a sealed reaction vessel containing NH₂, N₂, and H₂ at equilibrium at 400° C established the concentration of N₂ to be 1.2 M and the concentration of H₂ to be 0.24 M. N₂(g) + 3H₂(g) = 2NH₂(g) K = 0.50 at 400° C. What is the equilibrium molar concentration of NH₂ ? (B) 0.091 C) 0.24 3 Points D) 0.0091 3 Points
