CHEMISTRY 102, General Chemistry Fall 2014 Instructor: Ms. Laura Benton, labenton@email.unc.edu Office: Kenan Labs C142 (next to Chemistry Student Services, near Chemistry Resource Center) Class Times: Tuesday/Thursday, 2:00 – 3:15 PM, Stone Center 0103 Course Prerequisites: Chem 101 Group Office Hours: Monday, 11:30 – 12:30 AM, Chemistry Resource Center (Kenan Labs C147). Bring your questions about in-­‐class problems and homework and we will work them together. Individual Office Hours: Monday, 1 – 5 PM, Kenan C142. These hours are for individual meetings to discuss grades, study techniques, etc. Exam Review Sessions: These optional evening review sessions will be held the Monday prior to each exam from 8 – 9 PM. The dates are September 15th, October 20th, and November 24th. Location TBD. Mentor Recitations: Undergraduate mentors will be running optional recitations throughout the week to go over class topics. You may attend as many of these as you wish. All recitations are in Murray G202. Times are Thursday 4-­‐5 PM; Thursday 6 – 7 PM; and Friday 2 – 3 PM. Attendance: Not required, but highly recommended if you wish to be successful. You will need to be present to get participation points on Poll Everywhere. Class Website: Our class website is at http://sakai.unc.edu. Please check regularly for updates. In addition to powerpoints and additional resources for each chapter, there is a forum for you to pose any questions you have on content to your student colleagues. Required Textbook: Brown, LeMay & Bursten. Chemistry, the Central Science, 12th edition. The full solutions manual is available in the Chemistry Resource Center. Please read all sections of the textbook that we cover in class. Required Equipment: You will need a cell phone or laptop (with full batteries) to answer Poll Everywhere questions in class. You will also need a good scientific/graphing calculator. Please make sure you have both a backup calculator and extra batteries, especially during exams. You may not use any calculator during exams with wireless, network, or texting capabilities (no cell phones, iPad, iPod, etc). You may not share calculators during exams. Communication: Please come to office hours if you have questions about course content or your performance. If you are unable to attend scheduled hours for some reason, please post content-­‐related questions on the sakai forum. Please do not ask content-­‐related questions over email. Note that by law, I cannot discuss grading issues over email. I am unable to answer emails the day before an exam. Extra Help: The Chemistry Resource Center (Kenan C147) is open Monday – Thursday from 2 – 7 PM. The Learning Center at UNC (learningcenter.unc.edu/) has a plethora of free resources available. A list of tutors for hire is posted on the UNC chemistry website (chem.unc.edu) and I have a few folks I can recommend. If you’re starting to struggle, seek help ASAP. If you fail an exam, you are required to meet with me to discuss your grade. Technology: You may use laptop computers to take notes, but please stay on-­‐task. If your cell phone rings in class, I get to answer it. Please keep it on silent. Texting during the lecture distracts your classmates, so please keep all personal cell phone usage to a minimum. Grading Homework: The problems provided as homework in this syllabus will not be collected or graded. However, I highly recommend that you work through these problems multiple times for your own understanding. A solutions manual is available in the Chemistry Resource Center (Kenan C147). Please do not remove the manual from the resource center. Participation: You will be prompted in-­‐class to answer questions posed in lecture using a program called Poll Everywhere. Your answers to these questions will comprise 7% of your final grade. The total participation points available this semester from Poll Everywhere are 250, but the 7% used in grade calculations will be out of 200 points. This will give you a buffer in case of illness or technical difficulties. Exams: The remainder of your grade is based on: three hourly exams consisting of short answer questions; and one comprehensive, multiple-­‐choice final. If you have concerns about test-­‐taking, please consult the Learning Center. Please bring your one-­‐card to all exam sessions. Failure to bring your one-­‐card may result in a zero on that exam. The hourly exams will be on September 18th, October 23th, and November 25th. The final will be on Saturday, December 6th in our regular classroom at 12 PM. Please bring a scantron to the final exam. Important notes about exams: The hourly exams are optional. The final is required. There are no make –up exams. No exams will be given early. Re-­‐grading: A random selection of exams will be photocopied prior to their return. You may request a re-­‐grading of any exam, but note that any request must be applied to the whole exam, not just one question. Your score after re-­‐grading therefore could be higher OR lower than your original score. If you choose to have your exam re-­‐graded, you must turn in the exam, stapled to the required cover sheet (found on Sakai), no later than one day before the subsequent exam. Cheating and plagiarism: It is against the UNC honor code to cheat by any means, including looking on someone else’s paper, using cheat sheets/cell phones, passing notes/talking during an exam, etc. Policy adopted by the faculty of the Department of Chemistry on Sept. 9, 1977: "Since all graded work (including homework to be collected quizzes, papers, mid-­‐term examinations, final examinations, research proposals, laboratory results and reports etc.) may be used in the determination of academic progress, no collaboration on this work is permitted unless the instructor explicitly indicates that some specific degree of collaboration is allowed. This statement is not intended to discourage students from studying together or working together on assignments which are not to be collected.” How your final letter grade is determined: • If you take all three hourly exams, the lowest exam grade is dropped, and your final semester grade = 0.07 Poll Everywhere (PE) score + 0.25 hour exam + 0.25 hour exam + 0.43 final exam OR = 0.07 PE score + 0.18 hour exam + 0.18 hour exam + 0.57 final exam. I will take whichever one is higher. • If you take two hourly exams, your final grade = 0.07 PE score + 0.18 hourly exam + 0.18 hourly exam + 0.57 final exam. • If you take one hourly exam, your final grade = 0.07 PE score + 0.18 hourly exam + 0.75 final exam. • If you take no hourly exams, your final semester grade = 0.07 PE score + .93 final exam. Those who choose this option rarely earn the grade they want (usually failing). • There will be no changes to the way grades are calculated under this system. You may not, for example, take the hourly exams and then ask for your final exam score to count as your final grade. • The numerical ranges and their corresponding letter grades follows. There are no curves for individual exams. I reserve the right to curve final grades, but only at the end of the course and only if the final class average falls below the C range. Letter Grade A A-­‐ B+ B B-­‐ C+ C C-­‐ D F Numerical Range 93 – 100 90 – 92 87 – 89 83 – 86 80 – 82 77 – 79 73 – 76 70 – 72 60 – 69 Below 60 Schedule *All dates and topics are subject to change* Date August 19 August 21, 26 August 28, September 2 September 4, 9 September 11, 16 September 18 September 23 September 25, 30 October 2, 7 October 9 October 13 October 14 October 16 October 21 October 23 October 28 October 30, November 4 November 6, 11 November 13, 18, 20 November 25 November 27 December 2 December 6, 12 PM Topic Introductions, Chapter 10: Gases Chapter 10: Gases Chapter 11: Liquids and Intermolecular Forces Chapter 12: Solids and Modern Materials Chapter 13: Properties of Solutions Exam 1 Chapter 13: Properties of Solutions Chapter 14: Chemical Kinetics Chapter 15: Chemical Equilibrium Chapter 19: Chemical Thermodynamics Last day to drop a course Chapter 19: Chemical Thermodynamics No class, fall break Chapter 16: Acid-­‐Base Equilibria Exam 2 Chapter 16: Acid-­‐Base Equilibria Chapter 17: Additional Aspects of Aqueous Equilibria Chapter 20: Electrochemistry Chapter 21: Nuclear Chemistry Exam 3 No class, Thanksgiving Class Review Final Exam Homework Problems Reminder: Do not remove the answer key from the resource center for any reason.
