Methanol and water are miscible, they because of the formation of a. do not mix together, ion-dipole moment b. do not mix together; hydrogen bond c. mix together, ion-dipole moment d. mix together, hydrogen bond 6. Ideally, the van't Hoff factor, i, can be determined by the following equation moles of particles moles of dissolved solute What is the van't Hoff factor for BeClz? 2. Which of the following substance exhibits thec.3 most hydrogen bonding? a. HF b. NHs d. 4 7. Which statement regarding viscosity of liquid is not correct? d CHs (no hydrogen boad exists) a. Viscosity increases if the temperature increases since molecules move faster at 3. Based on the H:0 phase diagram, identify the significance of point (0.01 °C, 0.006 atm) and point (374 °C, 2 18 atm) a. Melting point and boiling point b. Melting point and critical point c. Triple point and boiling point d. Triple point and critical point higher temperature. b.
