Study the following phase diagram of Substance X. pressure (atm) 36- 18- solid 100 liquid 200 temperature (K) gas Use this diagram to answer the following questions. Sunnose a small sample of nure X is held at -104 C and 19.6 atm

This question as been getting rejected, but this is not a grade assigment. This just a pratice problem.

The pressure above a pure sample of solid Substance X at -10. °C is lowered. At what pressure will the sample melt? Use the phase diagram of X below to find your answer. pressure (atm) 04- 02- 6 0 atm solid liquid 400 temperature (K) Note: your answer must be within 0.025 atm of the exact answer to be graded correct. gas 600

Use the observation in the first column to answer the question in the second column. observation At 1 atm pressure, Substance E boils at 11. °C and Substance F boils at 30. °C. At 37 °C, Substance C has a vapor pressure of 89. torr and Substance D has a vapor pressure of 79. torr. The enthalpy of vaporization of Substance A is smaller than that of Substance B. question Which has a higher vapor pressure? Substance E Substance F Neither, E and F have the same vapor pressure. It's impossible to know without more information. Which has a higher enthalpy of vaporization? Substance C Substance D Neither, C and D have the same enthalpy of vaporization. It's impossible to know without more information. At any temperature where both substances are liquid, which has the higher vapor pressure? Substance A Substance B Neither, A and B have the same vapor pressure. It's impossible to know without more information. X Ś

The boiling point is directly related to the strength of the intermolecular forces between each molecule. Describe the different intermolecular forces that are present in toluene. Which of these intermolecular forces is strongest?

This graph shows how the vapor pressure of three liquids varies with temperature: vapor pressure, torr 900- 800- 700- 600- 500- 400. 300. 200- 100- 0 50 60 80 temperature, °C Use the graph to answer the following questions: 70 Which liquid is the most volatile? Which is the least volatile? What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. Suppose a beaker of acetone is put inside a sealed tank containing acetone gas at 54. degree C and 709. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? tetrahydrofuran acetone isopropyl acetate most volatile: least volatile: 90 tetrahydrofuran: acetone: isopropyl acetate: more less the same choose one choose one пос пос [°℃

Refer to the following phase diagram (not to scale!) for hydrogen: 12.8 1.00 atm 0.071 13.9 14.0 20.3 33.2 T Kelvin A sample of hydrogen at a pressure of 7.10x10 atm and a temperature of 11.4 K is compressed at constant temperature to a pressure of 18.2 atm. Which of the following are true? Choose all that apply O The liquid initially present will vaporize. O The final state of the substance is a solid. O The sample is initially a solid. O No phase change will occur. O The sample is initially a gas. Submit Answer
