Pickering, Tracey – Exam 3 – Due: Nov 9 2005, 3:00 pm – Inst: McCord 2 This print-out should have 25 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. The due time is Central time. 001 (part 1 of 1) 8 points The fact that gas pressures are additive is known as 1. Boyle’s Law. 2. Henry’s Law. 3. Dalton’s Law of partial pressure. correct 4. Charles’ Law. Explanation: Dalton’s Law of Partial Pressure allows us to sum the partial pressures of each of the gases in a mixture in order to determine the total pressure. 002 (part 1 of 1) 10 points The density of a gas can be changed. 1. True correct 2. False Explanation: The density mass volume · of a gas can be changed by varying its volume, which in turn can be changed by varying temperature and/or pressure. 003 (part 1 of 1) 9 points Which state of matter is characterized by hav- ing molecules close together and confined in their movement? 1. gas 2. All of these 3. liquid 4. solid correct Explanation: 004 (part 1 of 1) 10 points Consider four molecules I) CHCl 3 II) CH 4 III) CH 3 Cl IV) CCl 4 Which of these exhibit permanent dipole- dipole interactions? 1. I, III, and IV only 2. I and III only correct 3. III only 4. I only 5. None of these Explanation: Dipole-dipole interactions occur in polar molecules. CHCl 3 and CH 3 Cl are polar be- cause their dipole moments do not cancel. CH 4 and CCl 4 are symmetric; their dipole moments cancel and the overall molecule is non-polar. 005 (part 1 of 1) 10 points Which of the following cations is likely to be hydrated in compounds?

    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.
