CH302 Random Musings—A brief getting close to V-Day edition 1. There is a second quiz on Tuesday next week. The 8 question types for the exam are posted below—as noted this past weekend, I have decided that the coming quiz will be taken without a calculator. The questions will be constructed so that for students with even modest arithmetic and algebra skills, exact answers can be found when needed just using your head and scratch paper. You also are expected to understand logarithmic and exponential functions well enough to have a qualitative feel for the output from these functions and to do simple exponent math. I will do a demo of how I might prepare for a calculator-free quiz in a few minutes. 2. Question types for quiz 2 follow: • Colligative property calculation (with van’t Hoff factor involved) • Setting up an equilibrium expression • Using LeChatlier’s Principle to determine reaction direction (pressure or concentration change) • Using LeChatlier’s Principle to determine reaction direction (temperature change) • Comparing Q to K to determine reaction direction • Using the RICE set-up to find equilibrium values • Understanding the relationship between free energy and equilibria: ΔG = -RTlnK •Understanding the relationship between temperature and equilibria (Van’t Hoff equation) 3. We will have two delightful “calculator-free” practice quizzes available this weekend. I will have one posted by Saturday, and Travis will have one from the TAs by Sunday. 4. My office hours next week will be in the classrooms the beginning of the week and back to my office the end of the week. 5. Jessica’s office hours were mess up in the initial scheduling but are now settled. They are Monday from 4 to 5 pm in cubicle C. This is a perfect time to meet to prepare for the Tuesday quizzes. 6. The lecture and testing schedule—you may get a sense that the scheduling of exams and quizzes is a little odd. What is actually happening is that my first exam is a week later than usual because that is the time they assigned me to give the exam. The way it impacts you is that you will be taking quiz 2 and exam 1 on material that was presented in lecture the previous week, and the lectures given the week before the quiz and exam, respectively, are on material that will not be on the quiz or exam. For example, the next two lectures are on solubility products and acid base problems. The material from those lectures will not be on quiz 2. The good news is that this basically corresponds to you having a week to really learn the material on the quiz or exam. The bad news is that I know that you know that what I am presenting in lecture isn’t on the exam or quiz, and that consequently, you are less likely to pay attention. I think I just made things more confusing. 7. The TAs will have a brand new worksheet with questions on water autoprotolysis, solubility and simple monoprotic acid and base problems available this weekend—this worksheet will be a “calculator-free worksheet.” In the mean time, for those of you who are over-prepared for quiz 2 and want to get started on the new material, here is a really good worksheet on that material. Note that it basically covers every new topic for exam 1. http://laude.cm.utexas.edu/courses/ch302/ws5s08.pdf8. Public Service announcement. Are you interested in doctor shadowing?

Where is that love poetry? I know that most of you don’t believe in love or would rather just study for a test, but remember that I am taking love poetry dedications and actual written love poetry for next Tuesday’s musings. If you remember, please send it to me over the weekend. 9. In the mean time, here is love poetry written by famous people who are poetry for a living.Oranges By Gary Soto The first time I walked With a girl, I was twelve, Cold, and weighted down With two oranges in my jacket. December. Frost cracking Beneath my steps, my breath Before me, then gone, As I walked toward Her house, the one whose Porch light burned yellow Night and day, in any weather. A dog barked at me, until She came out pulling At her gloves, face bright With rouge. I smiled, Touched her shoulder, and led Her down the street, across A used car lot and a line Of newly planted trees, Until we were breathing Before a drugstore. We Entered, the tiny bell Bringing a saleslady Down a narrow aisle of goods. I turned to the candies Tiered like bleachers, And asked what she wanted - Light in her eyes, a smile Starting at the corners Of her mouth. I fingered A nickel in my pocket, And when she lifted a chocolate That cost a dime, I didn’t say anything. I took the nickel from My pocket, then an orange, And set them quietly on The counter. When I looked up, The lady’s eyes met mine, And held them, knowing Very well what it was all About. Outside, A few cars hissing past, Fog hanging like old Coats between the trees. I took my girl’s hand In mine for two blocks, Then released it to let Her unwrap the chocolate. I peeled my orange That was so bright against The gray of December That, from some distance, Someone might have thought I was making a fire in my hands. Sonnet #18 William Shakespeare Shall I compare thee to a Summer's day? Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And Summer's lease hath all too short a date: Sometime too hot the eye of heaven shines, And oft' is his gold complexion dimm'd; And every fair from fair sometime declines, By chance or nature's changing course untrimm'd: But thy eternal Summer shall not fade Nor lose possession of that fair thou owest; Nor shall Death brag thou wanderest in his shade, When in eternal lines to time thou growest: So long as men can breathe, or eyes can see, So long lives this, and this gives life to thee. How Do I Love Thee? Elizabeth Barrett Browning How do I love thee? Let me count the ways. I love thee to the depth and breadth and height My soul can reach, when feeling out of sight For the ends of being and ideal grace. I
