42. The deciding factor that makes HF a weak acid is that (A)the enthalpy of hydration of F⁻ is negative (B)HF has a large bond energy (C)the entropy for hydration of F⁻ is a large negative value (D)F₂ has a small bond energy (E)F⁻ has the largest ionization energy of all the halide ions

10. The kinetic-molecular theory of gases does not assume that (A)gases are made up of tiny particles in constant chaotic motion (B)gas particles are very small compared to the average distance between the particles (C)gas particles collide with the walls of their container in elastic collisions (D)the average velocity of gas particles is directly proportional to the absolute temperature (E)all of these are correct
