The vapor pressure of Substance X is measured at several temperatures: temperature vapor pressure 0.161 atm -38. °C -26. °℃ - 14. °C 0.242 atm 0.351 atm Use this information to calculate the enthalpy of vaporization of X. Round your answer to 2 significant digits. Be sure your answer contains a correct unit symbol.

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

A pure solid sample of Substance X is put into an evacuated flask. The flask is heated at a steady rate and the temperature recorded as time passes. Here is a graph of the results: temperature (°C) 160. 140. 120. 100. 80. 60. 0. 10. What is the boiling point of X ? Use this graph to answer the following questions: heat added (kJ/mol) 20. What phase (physical state) of X would you expect to find in the flask after 12 kJ/mol of heat has been added? 30. Пос (check all that apply) solid O liquid gas 40.

The vapor pressure of Substance X is measured at several temperatures: temperature vapor pressure 4. °C 0 16. °C 28. °C 0.0584 atm 0.0961 atm 0.152 atm Use this information to calculate the enthalpy of vaporization of X. Round your answer to 2 significant digits. Be sure your answer contains a correct unit symbol. x10 ロ・ロ X I olo Ś

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 [°℃

Try Again Your answer is incorrect. The enthalpy of vaporization of Substance X is 23.0 Round your answer to 2 significant digits. 0.32 atm x10 X kJ and its normal boiling point is 10. °C. Calculate the vapor pressure of Xat - 18. °C. mol S

The enthalpy of vaporization of Substance x is 7.00 kJ/mol and its normal boiling point is -10c . Calculate the vapor pressure of x at -36c. Round your answer to 2 significant digits
