Which of the following statements is correct about the liquid of these compounds? a. The boiling point of SeCl2 is higher than GeCl4 because SeCl2 has stronger dipole-dipole interactions than GeCl4 has.  b. Based on the information here, GeCl4 has a greater viscosity than SeCl2 at 25 oC.  c. The only intermolecular forces in SeCl2 liquid is London dispersion forces.  d. All three compounds have dipole-dipole interactions in their liquid.  e. The GeCl4 has a higher boiling point than PCl3 because GeCl4 has stronger dipole-dipole interactions than PCl3 has

- Which of the following should have the largest heat of vaporization?a) О2b) F2c) Br2d)cl2e) I2

Liquid X is known to have a lower vapor pressure and lower surface tension than Liquid Y. Use these facts to predict the result of each experiment in the table below, if you can. experiment 40.0 mL of Liquid X are put in one sealed 5 L flask, and 40.0 mL of Liquid Y are put in another sealed 5 L flask. The pressure in each fisk is slowly increased by pumping in argon gas. A 250 mL beaker is submerged in a large. container of Liquid X and turned upside down, and another 250 mL beaker is submerged and turned upside down in a large container of Liquid Y. Hydrogen (H₂) gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses my and my of hydrogen inside each beaker is then chemically determined. Note for advanced students: you may assume the solubility of H₂ in either liquid is very low. O predicted outcome Eventually both liquids boil, X first and then Y. Eventually both liquids boil, Y first and then X. Neither liquid will boil. It's impossible to…

Compounds such as CCl2 F2 are known as chlorofluorocarbons, or CFCs. These compounds were once widely used as refrigerants but are now being replaced by compounds that are believed to be less harmful to the environment. The heat of vaporization of CCl2 F2 is 289 J/g.
