Random Musings February 5, 2008—a brief one 1. There is a quiz on Thursday and an exam next Wednesday. I will have details about the exam on Thursday but for now be aware that it is from 7 to 9 in rooms to be determined and that if you have to take the make-up it will be the following Sunday night, no exceptions. Also, I will have an exam review on Sunday night as always. 2. Here are the 30 questions for exam 1: 30 question types for the exam 1 Physical Equilibria 1 temperature dependence of phase changes 2 vapor pressure theory 3 salt dissociation in water 4 phase diagram interpretation 5 phase diagram navigation 6 calculating ΔH from heating across phases transitions 7 gas solubility in liquids 8 ranking miscibility of liquids 8 calculating vapor pressure in binary system 10 Clausius Clapeyron equation 11 Van’t Hoff equation 12 colligative property application 13 colligative property calculation Chemical Equilibria 14 setting up K from equilibrium expression 15 appreciating the magnitudes of K 16 calculating equilibrium concentrations from K 17 calculating equilibrium concentrations from K 18 determining reaction direction from Q and K 19 LeChatelier and reaction direction 20 LeChatelier and reaction direction 21 relationship of ΔG to K Introduction to Water Equilbria 22 theory of auto-protolysis of water 23. temperature dependence of Kw 24. converting between pH, pOH, [H+]+ and [OH-] 25. ranking acidity and basicity based on equilibrium constants 26. strong acid or base calculation 27. weak acid or base calculation 28 weak acid or base calculation 29. identifying acid and base strength 30. simple buffer calculation 3, I have learned that the office hours being held by the TAs are very poorly attended. I assume this will pick up with the quizzes and exams coming up. We are talking about almost one on one tutoring. Make use of it. 4. A bit of advice if you can’t get in to the Chem Portal or once there, can’t seem to find my practice quizzes: make sure you register for the 302 course when you get to the entrance to the portal and BEFORE you log in. 5. The 16 of you who paid full price for the book have been credited $40.6. Since it isn’t Valentine’s Day till next week, it seems reasonable to do hate poetry this week.
