Please help me with questions 23 & 24. Thank you in advance

19. How many lattice points does it require to fully define a face-centered cubic unit cell? - a. 2 - b. 4 - c. 8 - d. 9 - e. 14 20. In the accompanying phase diagram, a liquid can be present at combinations of temperature and pressure corresponding to points - a. A, B, C, and G - b. A, C, G, and D - c. G, C, D, and E - d. A and D only - e. A, C, D, and F **Phase Diagram Explanation:** The diagram shows a curve on a Pressure (P) vs. Temperature (T) plot with points labeled A, B, C, D, E, F, and G. The curve suggests phase boundaries. 21. When a liquid undergoes a phase change to a gas, the process is called - a. condensation - b. deposition - c. fusion - d. sublimation - e. vaporization 22. Which of the following is most volatile? - a. CBr₂H₂ - b. CCl₃H - c. CBr₄ - d. CCl₄ - e. CF₄ 23. The boiling point of Br₂ is higher than Cl₂ due to - a. dipole-dipole forces - b. London forces - c. hydrogen bonding - d. covalent bonds - e. magic 24. Which of the following has the highest boiling point? - a. Xe - b. Kr - c. Ar - d. Ne - e. He 25. For which of the following substances would hydrogen bonding be most important? - a. H₂Se - b. H₂S - c. H₂Te - d. H₂O - e. HBr 26. The boiling point of H₂O is higher than H₂S due to - a. ion-dipole forces - b. hydrogen bonding - c. London forces - d. covalent bonds - e. magic 27. The meniscus of water curves upward in a glass tube forming a "U" shape. This means - a. water has a low surface tension - b. water tends to cover
