The vapor pressure of liquid hexane, C6H14. is 100. mm Hg at 289 K A sample of C6H14 is placed in a closed, evacuated 513 mL container at a temperature of 289 K. It is found that all of the C6H14 is in the vapor phase and that the pressure is 59.0 mm Hg. If the volume of the container is reduced to 375 mL at constant temperature, which of the following statements are correct?
a. Some of the vapor initially present will condense.
b. Liquid hexane will be present.
c. No condensation will occur.
d. The pressure in the container will be 100. mm Hg.
e. Only hexane vapor will be present.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
