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 '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.

There are three sets of sketches below, showing the same pure molecular compound (water, molecular formula H₂O) at three different temperatures. The sketches are drawn as if a sample of water were under a microscope so powerful that individual atoms could be seen. Only one sketch in each set is correct. Use the slider to choose the correct sketch in each set. You may need the following information: melting point of H₂O: 0.0 °C boiling point of H₂O: 100.0 °C A (Choose one) (Choose one) 188. °C B 5 35. °C 4 5 (Choose one) -25. °℃

Based on the graph which describes two liquids, A and B, select ALL of the FALSE statements. XA OA The substance with the higher pure vapor pressure (P") is B OB. The substance with the higher pure vapor pressure (P°) is A OC. For any mixture of A and B (any ratio of A and B), the mole fraction of B in the vapor phase will be larger than the mole fraction of B in the liquid phase. OD. An equimolar mixture of liquids A and B are placed in a closed container (25 °C).

Enter your answer in the provided box. The vapor pressure of a liquid doubles when the temperature is raised from 75°C to 85°C. At what temperature will the vapor pressure be five times the value at 75°C?

The organic compound trans-anethole is found in many oils/flavorings.  This compound has a melting point of 50. ∘F.   On Tuesday (this is a true story), a friend left a small vial of this compound in her back seat of her car outside for an hour and it solidified.  At what temperature in ∘C does this compound freeze?  We used this flavoring to make a holidy candy flavored with anise.

In addition to filling in the blanks below, show all of your work for this problem on paper for later upload. The heat of vaporization of isopropanol is 44.0 kJ/mol. The vapor pressure of isopropanol at 400 torr is 67.8 °C. Calculate the normal boiling point of isopropanol. Enter your value in the first box and an appropriate unit of measure in the second box.
