1 COURSE SYLLABUS CHEM 103: General Chemistry- Fall 2010 University of Wisconsin-Eau Claire Instructor Dr. Sudeep Bhattacharyay Office P-452 Office Phone Office Hours By appointment Course Website Lecture G0G P-117, T, R 6:00 7:15 PM Lab G01 P-469, M PM Lab G02 P-469, W PM CHEM 103 course and its objective Chemistry is the study of properties and transformations of matter. The main objective of CHEM 103 is to help you in developing a picture of matter and their properties at the atomic and molecular levels. Topics of the CHEM 103 course include mathematics in chemistry, structure of atoms, atomic properties, periodic trends, the bonding and molecular structure, the physical states of matter, chemical reactions types, chemical equations, and stoichiometry. Laboratory experiments will allow us to examine theories we learn in lectures. Besides chemical theories and experimental skills, this course is also designed to impart critical thinking ability to solve problems. Chemistry is a subject that delivers a central platform to study other disciplines like biology, geology, material science, physics, medicine, and many branches of engineering. It is extremely relevant for businesses as chemistry plays an important role in our economy (we consume a large variety of chemicals every day). Relevant Goals of the Baccalaureate Degree This course is intended to help students develop the following: Knowledge of Human Culture and the Natural World Individual and Social Responsibility Respect for Diversity Among People Effective Communication Creative and Critical Thinking Required Materials Textbook: Silberberg, Chemistry The Molecular Nature of Matter and Change, 5 th Edition, McGraw Hill,

2 Calculator: Scientific calculator capable of executing typical mathematical operations, including logarithms, exponential functions, etc. and handling scientific notation. You should bring your own calculator to lecture and lab. If you are concerned about battery failure during the exam or lab, bring extra batteries with you. Lab needs: CHEM 103 Lab manual: Obtain at first lab meeting Safety goggles (fit tight to face to meet ANSIZ87.1 standard) available for purchase from bookstore iclickers In each lecture, a handful of questions will be asked and you would need to respond to with the clickers. Your responses to questions will be recorded. The purpose behind the clickers is primarily to encourage you to think and respond to questions. You will be awarded 80% for participation and an additional 20% for answering the questions correctly. Your participation will also be used to monitor your attendance in lecture. The clicker responses will be used to award up to about 3% (25) extra-credit points to your final semester grade. Therefore, please bring your clickers to every class. The clickers are available for purchase at the University Bookstore. The University has adopted iclicker as the campus standard. So you will need to purchase a single iclicker for all of your classes. Laboratory The laboratory is an important part of the CHEM 103 course and will count 20% toward your course grade. All students are encouraged to go through the assigned lab material before the lab. There will be a brief pre-lab quiz based on the material to be covered. Most experiments will be performed in pairs or groups, however, some in-lab practical exercises will be performed individually. Points will be awarded based on their overall performances in the lab that will include pre-lab quiz, completion of required lab activities, post-lab assignments and in-lab practical exercises. Students must complete ALL laboratory assignments to pass the course. Homework Problems A list of recommended homework problems for each chapter is included in the tentative lecture schedule. All students are STRONGLY encouraged to solve all of these problems. These will not be collected or graded, however, it will help you think critically and practice your problem solving skills. There will also be some homework assignments that will be graded and will count 100 total points towards your course grade. 2

3 Quizzes There will be a short (~20 minute) quiz each week except the exam weeks and will count ~20% toward your course grade. The quizzes will be announced and will be based on the material presented in the lecture, assigned reading, and recommended homework problems. Exams There will be total of four exams in this course. Three midterm exams will be given as outlined in the tentative lecture schedule. The FINAL exam will be comprehensive and is scheduled for December 13 ( PM). Exam questions will be based on all material covered in lecture and lab. Attendance Attendance is important! Students who regularly miss class will be reported to the Associate Dean of Students in accord with University attendance policies. It is assumed that every student is present at every class and lab. So, it is YOUR RESPONSIBILITY to obtain missed lecture notes, copies of handouts, etc. Make-up quizzes and exams will not be given. Students missing quizzes or exams without a valid reason (proper documentation required) will receive a grade of zero. However, if you missed the quizzes or exams because of an excused absence (proper documentation required), a prorated (avg) grade will be given for the missed one. Academic Integrity Academic misconduct in any portion of the academic work for a course is a serious offense. Students found guilty will be punished by a failing grade in the course. The disciplinary procedures and penalties for academic misconduct are described in the UW-Eau Claire Student Services and Standards Handbook in the section titled, Chapter UWS 14 Student Academic Disciplinary Procedures. Students with Disabilities Any student who has a disability and is in need of classroom accommodations, please contact the instructor and the Services for Students with Disabilities Office in Old Library 2136 at the beginning of the course. Summary of Grading Scheme Midterm exams: 300 points (100 x 3) Quizzes: 100 points (20 x 5) Final exam: 180 points Lab: 150 points Homework: 100 points Total: 830 points 3

4 Grading The percentage required for a specific final grade: % A, A % B+, B, B % C+, C, C % D+, D, D- Below 50 % F Grade updates will be made at Desire2Learn (D2L) ( Some Study Hints This course requires a significant amount of time from you. Please be aware of the intense involvement of you in order to do well in the course. Please be engaged in the class and in the lab. Please participate as much as possible. Here are some basic advises: Active classroom participation. Some lecture contents in power point handouts will be available at Taking notes and in-class problem solving will be the best way to prepare yourself. You are also encouraged to participate in the class by asking questions, actively engaging into discussions, and volunteering in activities if needed. Making your notes. It is the key to study any subject. Make your own notes. After you have taken notes from the lecture, make summaries of key items for later review. I will suggest you to make separate summaries of a) key definitions, b) statements of key laws that are encountered, c) key equations, and d) different problem types you encounter. Know what you are going to do in advance. I would request you to read the appropriate section(s) in advance and form a basic idea about the central question that will be discussed in the lecture. You are also strongly encouraged to go through the objective section of each experiment before coming to the lab. Do the end-of-chapter exercises. You are supposed to do all exercises (homework problems) as well as those recommended in the Objective section for each chapter. If you have extra time available, you should try additional questions beyond those that have been assigned. Doing more and more problems not only help you to understand the theory but also prepare you for the exams/quizzes. Finally, it is our constant effort to create a positive learning environment for you. Chem 103 is a demanding course and we expect you to put a consistent and diligent effort to learn. We commit full support to your efforts. Finally, I would also expect you to treat all class members, instructors, teaching apprentices, and other staff members in the department, with respect. 4
