Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select 'l' next to the...

answer 1-4
Which of the following (a-d) is TRUE regarding solid NaCl dissolving in water The attraction of the water to the ions in NaCl is through dipole-dipole IFs. Water is considered the solute and NaCl the solvent. The partially positive oxygen in water is attracted to the chloride ion. d. The process of separating the sodium ions from the chloride ions is endothermic. All of these statements are true. polar For the following solution, describe the deviation with respect...
