CHEM 10: General Chemistry II Fall 2010 Course Syllabus General information: CHEM 10 is the second in the two-semester general chemistry sequence at UC Merced (CHEM 2/CHEM 10). This course will address the properties of gases; chemical thermodynamics including entropy and free energy; electrochemistry; chemical kinetics including rate laws and reaction mechanisms; quantum mechanics and molecular structure and spectroscopy; properties of solids and liquids; and nuclear chemistry. The associated laboratory section demonstrates and reinforces concepts introduced in the lecture, and teaches basic laboratory methods and scientific methodology. Instructor: Prof. Anne Myers Kelley, SE 374, (209)-228-4345, amkelley@ucmerced.edu Learning outcomes: Upon successful completion of CHEM 10, students should be able to: Describe qualitatively the behavior of gases, thermodynamic considerations governing chemical equilibria, oxidation-reduction reactions and electrochemical cells, the factors that determine the rates of chemical reactions, basic theories of chemical bonding, how molecules interact with light, and the properties of liquids and solids. Solve quantitative problems involving gas laws, chemical thermodynamics, electrochemistry, chemical kinetics, and elementary molecular spectroscopy. Carry out experiments and operate basic laboratory apparatus with proper experimental technique, attention to safety procedures, and treatment of data. Prepare brief laboratory reports that clearly communicate methods, results, and conclusions. Evaluation will be based on laboratory reports, quizzes, midterm exams, and a final exam. Homework problems will be assigned, but not graded. Homework is viewed as a learning aid rather than an assessment tool. Relationship to program learning outcomes for the Chemical Sciences major: CHEM 10 focuses primarily on fundamental knowledge and skills. This course develops some of the major concepts and theoretical principles in chemistry, building on the foundation established in CHEM 2. You will further develop the skills required to carry out basic laboratory procedures in a safe manner and with proper technique. To a lesser extent, this course will explore scientific methodology how a scientist integrates fundamental knowledge and skills into scientific inquiries. The laboratory reports you prepare will involve basic scientific communication skills. Finally, you will gain an appreciation for scientific ethics and the role of chemistry in society by learning how to handle data in the laboratory as well as through some of the examples of chemical applications given in the textbook and discussed in lecture.

You may also submit questions via e-mail, but questions received after noon on the day before an exam may not be answered before the exam. Course Web site: The CHEM 10 web site is part of the UCMCROPS course management system and will be automatically available to all students enrolled in the class ( https://my.ucmerced.edu ). This web site contains descriptions of the laboratory experiments (under Resources ), electronic copies of the course syllabus, and solutions to the midterm exams once they are graded. Course grading: Points will be assigned as follows: possible points Quizzes (10 points each for best 10 out of??) 100 Laboratory reports (25 points each for best 10 out of 11) 250 Midterm exams (three exams at 125 points each) 375 Final exam 275 Total points 1000
Grades: Grades will be assigned according to the following approximate percentages: 90 100 A, 78 90 B, 63 78 C, 50 63 D. Plus and minus grades will be assigned within these ranges at Prof. Kelley s discretion. Exam Dates: Midterm exams will be given during regular class periods on Sept. 24 (Friday), Oct. 25 (Monday), and Nov. 24 (Wednesday). The final exam will be given Monday, Dec. 13 from 8:00-11:00 am at locations to be announced. The final exam will cover the entire course, but with greater weight on material not previously tested. An unspecified number of unannounced quizzes will be given during lecture on randomly chosen dates. Quizzes will be administered using the clicker system. The ten best will count toward your grade. No make-ups are allowed. Bring your clicker, a calculator, paper, your student ID, and something to write with (in case scratch work is necessary) to class every day in case there is a quiz. In order to receive credit for quizzes, you must register your clicker: Login to the Portal (my.ucmerced.edu) Click on the My Profile tab In the Identity Management Services channel click on "Update Your Clicker ID" Enter the Clicker ID in the field and click Save [The 6 digit Clicker ID can be found just below the bar code on the back]. Deadlines to drop a course: Course Drop (without a W ): Tuesday, September 21, 2010 Course Withdrawal (with a W ): Monday, November 1, 2010 Policy on missed assignments: No quizzes, laboratories, or exams may be taken late. If you miss a quiz, lab, or midterm, it will count as a zero. Only two exceptions will be made: incapacitating injury or illness (requires written documentation from your physician or Student Health Services specifying the date on which you were incapacitated) or death or serious illness of an immediate family member (requires written documentation from Student Advising). In these cases, a score for the missed assignment will be generated based on your average scores for the other assignments of the same type (quiz, lab, or midterm). If you miss the final exam for a valid reason, documented as described above, you may request a grade of Incomplete for the course (this will be given only if you were doing passing work prior to the final) and you must take the final exam during Spring semester in order to complete your grade. If you know in advance that you will have a conflict between an exam or laboratory period and a planned extracurricular activity, you may be able to arrange to do a lab during another lab section or to take an exam early. Such accommodations are not guaranteed. You must see Prof. Kelley at least two weeks before the scheduled date in order to discuss such arrangements. Structure of the course and expectations: You are expected to read each assigned chapter in Zumdahl before the class period in which that chapter is discussed. The lectures will consist mainly of discussions of several specific questions that highlight the concepts presented in the chapter. Unless informed otherwise, you are responsible for all of the material in the chapter, whether or not it is specifically discussed in lecture. The lab/discussion periods will be used primarily to complete the eleven laboratory experiments. Some of the labs are done individually while others may be done in pairs or groups. The descriptions, procedures, and write-up formats for the labs can be found on the course web site under Resources. Most of the labs have pre-lab assignments. For those that do, the pre-lab should be done on a separate page in your lab notebook and the duplicate page must be turned in to your laboratory instructor at the start of the lab period. The rest of the write-up for each lab will be due at the beginning of the following laboratory
period except for the last lab, which must be turned in during lecture the following week (no later than Dec. 8). No lab write-ups will be accepted late. Late = zero points! The lowest score among the 11 will be dropped when calculating your course grade. Homework problems will be assigned from each chapter in Zumdahl. They are intended to help you learn the material. They will not be turned in or graded, but you are encouraged to ask Prof. Kelley or your TA for help if you have difficulty in understanding the problems or getting the correct answers. The exams are structured to emphasize understanding of concepts and methods of problem solving, not memorization of facts. You will always be provided with a periodic table as part of the exam booklet. In addition, you will be given data such as physical constants (Avogadro s number, the gas constant, certain unit conversions) that you may need. The information that will be provided for each exam will be posted on the course Web site at least one week before the exam. You will be allowed to bring to each exam one sheet of paper (standard 8½ x 11 inches, both sides of the page) on which you may write or print any other facts or formulas you think may be helpful on the exam. Calculators will be allowed on midterm 1 and the final exam, but not on midterms 2 and 3. Use of any other materials on an exam constitutes cheating (see Academic Honesty policies below). Attendance and behavior: Students are expected to attend lectures. Attendance will not be taken, but material not in the textbook may be discussed for which you will be held responsible on exams, and quizzes may be given on any day. Attendance at your assigned lab/discussion section is required in order for you to earn the points for the lab write-ups. Behavior that is disruptive to other students or interferes with their attempts to follow the lectures is not allowed. This includes talking (except when you are specifically asked to discuss a question among yourselves), listening to music or operating an electronic device that makes any audible sound, or blocking another student s view. Cell phones must be turned off while class is in session. Violators of these policies will be required to leave the classroom. Regrading: If you believe that any assignment has been graded incorrectly, you may return the assignment for regrading within one week after it was returned to you. Exams should be returned to Prof. Kelley; lab reports should be returned to your laboratory instructor. The entire assignment will be regraded, so your score could go either down or up. The instructors may photocopy graded assignments before returning them. Any student who attempts to cheat by altering a graded assignment and returning it for regrading will receive a score of zero for that assignment and may be subject to further disciplinary action. Academic honesty: The progress of the scientific enterprise relies crucially on the integrity of scientists, and I take academic honesty very seriously. Students in CHEM 10 are expected to be familiar with and adhere to UC Merced s academic honesty policy (go to http://studentlife.ucmerced.edu/, click on Student Judicial Affairs and then Academic Honesty Policy ). Laboratories: You are free to discuss any aspect of the laboratories with anyone and to consult any reference sources while preparing for the laboratories, performing the experiments, and writing the reports. You must, however, perform your own work in the laboratory and report your own data and observations. For experiments that are to be carried out in pairs or groups, everyone in the group is responsible for the experiment and all data and observations must be recorded by each member of the group and reported. An observation or piece of data may be thrown out only if you know, or have good reason to believe, that a mistake was made on that part of the experiment, and in that case the lab report must clearly indicate which data were eliminated and why. You must not interfere with any other individual s or group s experiment, and you are responsible for handling shared chemicals and equipment in ways that will not contaminate or damage them. If you use information from outside sources in preparing your lab report, those sources must be properly credited. Each student must prepare an independently written lab report
even for experiments that were performed in pairs or groups. If multiple students submit lab reports that have obviously been copied, entirely or partially (apart from the common set of original data), all of the students involved will receive scores of zero for that report. Quizzes and Exams: Quizzes and exams must be your own independent work. You may use only a calculator (for quizzes, midterm 1 and the final exam), pencils and/or pens (for exams), and your one sheet of notes (for exams). You may not communicate with or pass materials to any other person, look at another student s paper, or consult any other written or electronic source during the exam or quiz unless you are specifically told otherwise. You may not take a quiz for another student using his/her clicker or give your clicker to another student to take a quiz for you. Computers and cell phones must be turned off and out of sight during exams. Bring your UC Merced student ID to class every day. Students not carrying proper ID may be prohibited from taking the exam or quiz and assigned a score of zero. Any student caught violating these policies will be assigned a score of zero for that quiz or exam and may be subject to further disciplinary action. Students with disabilities: UC Merced is committed to ensuring equal academic opportunities and inclusion for students with disabilities. Any student who feels he or she may need an accommodation based on the impact of a disability should contact me privately to discuss his or her specific needs. Also contact Disability Services at (209) 228-7884 (disabilityservices@ucmerced.edu) as soon as possible to become registered and thereby ensure that such accommodations are implemented in a timely fashion.
