Basner Lectures: MWF 12:45-1:40 PM (section M013) Office: 2-016c CST Room: Stolkin Auditorium, Physics Bldg Office hours: Wed, 2-5pm or by appointment Credits: 3 adbasner@syr.edu Prereq: none Chemistry Undergraduate Secretary: TAs: Nick Azzarelli, njazzare@syr.edu, Nancy Virgil, 120 LSB, x2851 Melanie Blanden, mjdecker@syr.edu Web site: Chris Blanton, cjblanto@syr.edu Books: Chemistry, The Central Science, 12 th ed. (Syracuse University Edition) by Brown, LeMay, Bursten, Murphy, and Woodward (Pearson-Prentice Hall, 2011) Student Guide, 12 th ed. by Hill (Pearson-Prentice Hall, 2011) MasteringChemistry login information ( Register using your Syracuse University NetID and Course ID: MCBASNER63832 The above book and supporting materials can be purchased as a package from the S. U. Bookstore. The books are also available on reserve at the Science and Technology Library. Course Description: Chemistry is often called the central science. One cannot achieve a thorough understanding of any of the sciences if one does not know something about chemistry. Conversely, even a rudimentary understanding of chemistry is an enormous asset not only in the study of other sciences, but also in the appreciation of our everyday environment. Helping students to gain an appreciation and understanding of the chemistry that occurs around them is a goal of this course. Another general goal is to provide a sense of how science is done, that is, how knowledge is gained and contributions are made by scientists. This is an important part of scientific literacy, and is a topic about which many misconceptions exist. Specific topics covered this semester will include atomic structure, chemical reactions, stoichiometry, energy and thermochemistry, bonding, and gases. We will study these topics both at a conceptual level and at a quantitative level. Basic skills in algebra will be required to solve the quantitative problems. Assignments and Lectures: Reading assignments from the text are given on the course calendar. I expect that you will read the assignments before the class meetings for which they are listed. I also expect that you will attend all lectures. In lecture, we will reinforce important concepts from the reading and apply these concepts. You will be tested on material from the reading and from lecture. Some of this material will come only from the book, and some will come only from lecture. While reading the text, you should do all of the in-chapter sample exercises. In addition, doing at least representative exercises from the end of each chapter will be very helpful. The textbook contains the answers to the odd-numbered problems. The Solutions Manual contains detailed solutions to these problems and several copies are held on reserve in the Science and Technology Library (Carnegie Library Building). If you are having difficulty, refer to the Solutions Manual and Student Guide to support your learning.

2 The required MasteringChemistry homework will also provide valuable practice. It is imperative that you do lots of problems, because there is no substitute for this in the learning of chemical concepts! Do not be tempted to discount the online homework since it is worth "only 10%". It is actually worth much more, since your exams scores will rise as a result! If you take shortcuts on the homework, you might get the 10%, but your exam scores will suffer. The MasteringChemistry site has resources that go beyond the assigned homework, including the etext with hyperlinks and other features and a study area that allows selftesting and exploration of animations, videos, and more. You can also use the assigned homework for self-study even after you have submitted answers. The Student Guide is also a valuable resource for organizing your study and for additional problems. Your goal should be to do problems until they become easy not just doable! If you "do" the problems by looking up the answers in the solutions manual or in the back of the book (or by just clicking for hints), you will learn very little. For best learning, do as much as you can before checking the solutions or requesting hints. If you do enough problems so that they become easy, the exams will be easy too! If you wish to succeed in this course, I strongly recommend that you block out 8 or 9 hours in your weekly schedule for study time for this course. You might find that you do not need this much time each week, and in those weeks you can spend your time having non-alcoholic dance parties. If you try to cram and only study mainly before exams, you will likely fall short. Students whose goal is to do the minimum work required to receive a decent grade usually underestimate by good bit, do not learn very much, and end up unhappy with their grade. Lecture notes will be available on Blackboard. Time in lecture will be best spent if you are an active participant, and many students have trouble thinking about questions that are asked about the material while taking notes. The notes are provided so that you can get the most out of this time. I recommend that you copy the notes by hand later, because people tend to remember material that they write far better than material that they only read. Recitations: Recitations will begin in the second week of classes. While attendance at recitation is not required, any student aiming to succeed in the class should go every week. If what the TA is doing in recitation is not helpful to you, talk to the TA and make suggestions. If the TA is not responsive, talk to me. You are also welcome to attend any other or all recitations that you have time for and wish to attend. Office Hours: I will be available to answer questions and deal with problems or concerns during office hours, listed above. You may also contact me for an appointment or just stop by to see whether I am free. In addition, teaching assistants will be available during their office hours and at recitation. You can ask questions of any of the CHE 106 TAs, not just those associated with this lecture. (The CHE 106 TAs and I have no role in CHE 107, so please direct you lab questions to the instructor and TAs for that course.) You should find it easy to obtain help. If you need more extensive help, contact the Tutoring and Study Center (111 Waverly Ave., Suite 220, (315) If you are having any trouble in the course, do not wait to get help! Getting on track is much easier earlier in the semester!

3 TA Office Hours All TA office hours will take place in room LSB 122 and are as follows. Recitation hours for TAs in the other general chemistry sections will be posted outside LSB 122. Nick Azzarelli, Thursday 1pm-3pm Melanie Blanden, Tuesday, 11am-12pm Chris Blanton, Thursday, 12pm-1pm, Friday 11am-12pm Laboratory: Students in this course should take concurrently the accompanying laboratory course, Chemistry 107. Note, however, that the two courses are separate, including grading. Exams: Exams will cover both material covered in lecture and the assigned text readings. Some questions will come from lecture (not covered in text) and others from the text (not covered in lecture). Many questions will be problems similar to assigned homework exercises. Lots of practice with problems is the key to success in this course. Each hourly exam will focus on specific chapters. The final exam will be cumulative and cover the entire semester. Regular exams (but not the Final) are given during the regular class period and are scheduled as follows: First Examination Friday, September 27 th Second Examination Friday, October 25 th Third Examination Friday, November 22 nd FINAL EXAMINATION WEDNESDAY, DECEMBER 11, 5:15-7:15 PM Room to be announced MAKE YOUR TRAVEL PLANS NOW. NO ACCOMMODATIONS FOR STUDENT TRAVEL/EXAM CONFLICTS WILL BE MADE. (The one exception is sports-related travel of student-athletes who have turned in the appropriate form at least one week in advance.) Grading: Three examinations will be given, and the average of the three will represent 60% of the final grade. The final examination will be comprehensive and will count for 30%. The homework on MasteringChemistry will count for 10%. Guaranteed grade levels are as follows: 90% A; 86% A-; 82% B+; 78% B; 74% B-; 70% C+; 65% C; 60% C-; 50% D. Actual numeric cutoffs may be lower but will not be higher. Student responsibilities: Attend lectures and read the appropriate material prior to class time. Study your lecture notes and assigned text reading. Attend recitations and use the Student's Guide to help reinforce your learning. Do assigned homework on time and review them before exams. Do not fall behind! BRING A CALCULATOR TO ALL LECTURES, RECITATIONS, AND EXAMS. GRAPHING CALCULATORS WILL NOT BE ALLOWED ON EXAMS. Take all of the examinations. If you have any questions about the homework, the in-class exams, the final exam, or anything else, it is the responsibility of the student to contact me to get help in a timely manner.

4 Recitation Schedule/Homework Due Dates: The following weekly schedule shows material that will be discussed in the recitations and the homework that is due on the MasteringChemistry website. The textbook contains the answers to the odd-numbered problems. The Solutions Manual contains detailed solutions to these problems and several copies are held on reserve in the Science and Technology Library (Carnegie Library Building). If you are having difficulty, make use of the Solutions Manual and Students Guide to support your learning. The TA office hours in LSB 122 are also an excellent resource. All homework is to be done and submitted on the MasteringChemistry website. No exceptions. The MasteringChemistry Tutorials and Homowork, due on Saturdays, are mandatory and they are graded. These are intended to help prepare students for lecture and the following exams. The Review Sections of the homework are due on Wednesday the weeks of the exams. Consult the MasteringChemistry website for the assigned problems.

6 Academic Honesty (from Syracuse University s Academic Integrity Policy holds students accountable for the integrity of the work they submit. Students should be familiar with the policy and know that it is their responsibility to learn about course-specific expectations, as well as about university policy. The university policy governs appropriate citation and use of sources, the integrity of work submitted in exams and assignments, and the veracity of signatures on attendance sheets and other verification of participation in class activities. The presumptive penalty for a first offense by an undergraduate student is course failure, accompanied by a transcript notation indicating that the failure resulted from a violation of Academic Integrity Policy. For more information and the complete policy, see In this course, students are allowed and strongly encouraged to study together, but exams and online homework must represent the work of the individual student. Online homework must be completed by each student using his or her own access account, though reference to the text and lecture notes is allowed. Syracuse University s Religious Observances Policy: SU religious observances policy, found at recognizes the diversity of faiths represented among the campus community and protects the rights of students, faculty, and staff to observe religious holidays according to their tradition. Under the policy, students are provided an opportunity to make up any examination, study, or work requirements that may be missed due to a religious observance provided they notify their instructors before the end of the second week of classes. For fall and spring semesters, an online notification process is available through MySlice/StudentServices/Enrollment/MyReligiousObservances from the first day of class until the end of the second week of class. The religious observances policy requires accommodation for the religious holiday itself, not for travel days if a student will be observing the holiday elsewhere. Medical Absences: Medical absences will be excused based on written advice from the Health Center or a health-care provider (based upon clinical findings and prescribed treatment recommendations). NO VERBAL EXCUSES WILL BE ACCEPTED. The medical document must specifically indicate that you were unable to attend class/recitation. There will be NO makeup examinations except in the case of advance-notice approved absences. All advanced-notice approvals will result in an opportunity to take the exam in advance, not after the regularly scheduled exam time. An approved absence that prevents a student from taking an exam on-time or early will result in the dropping of that particular grade from the calculation of the overall grade. Disability Accommodation: If you believe that you need accommodations for a disability, please contact the Office of Disability Services(ODS), located in Room 309 of 804 University Avenue, or call (315) or TDD: (315) for an appointment to discuss your needs and the process for requesting accommodations. ODS is responsible for coordinating disability-related accommodations and will issue students with documented Disabilities Accommodation Authorization Letters, as appropriate. Since accommodations may require early planning and generally are not provided retroactively, please contact ODS as soon as possible.
