HW Set #8 Due (11/16/10) at the beginning of class Work the following problems in chapter 10 16, 18, 19, 20, 24, 28 Work the following problems in chapter 9 8, 14, 18, 28, 34, 42, 57, 80, 94 More problems Ethanol (CH 3 CH 2 OH) and Dimethyl Ether (CH 3 OCH 3 ) both have 2 carbons, 6 hydrogens, and an oxygen. Which do you think will have a higher boiling point. Explain in terms of specific intermolecular forces? Air is primarily a mixture of N 2 and O 2 . At 25° which gas has a higher average kinetics energy (or are they the same)? Which gas has a high average speed (or are they the same)? Which has a faster mean square velocity, H 2 at temperature T or He at a temperature of 1.5T? At 298.15 K and a pressure of 100 bar, 1 mole of a real gas has volume of 0.238 L.

Unformatted text preview: Are the intermolecular forces for this gas dominated by repulsions or attractions? Of the following gases which would you expect to be have the most ideally and which the least? NH 3 , CH 4 , Ar Acetylene gas C 2 H 2 reacts with hydrogen H 2 in the presence of a catalyst to form ethane C 2 H 6 . Write a balanced equation for this reaction (all species are gases). If 1 mole of acetylene is mixed with 4 moles of hydrogen and the reaction takes place in a container at a constant pressure of 1 atm and a temperature of 100°C what is the final volume of the container? What are the partial pressures of the gases that remains after the reaction?...

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
