31. Two liquids form a solution and release a quantity of heat. How does the pressure above the solution compare to that predicted by Raoult's law? (A) It will be greater. (B) It will be less. (C) It will be the same. (D) It will show positive deviation. (E) None of these.

35. The complex ions of Zn2+ are all colorless. The most likely explanation for this is: (A) Zn2+ is paramagnetic. (B) Zn2+ exhibits “d orbital” splittings in its complexes such that they absorb all wavelengths in the visible region. (C) Since Zn2+ is a d10 ion, it does not absorb visible light even though the “d orbital” splittings are correct for absorbing visible wavelengths. (D) Zn2+ is not a transition metal ion. (E) None of these is correct.
