Safety goggles GENERAL COURSE OVERVIEW: This class is the follow-on course to CHM 157. The fundamental skills and ideas covered in CHM 157 are applied to more advanced topics such as the rates of chemical reactions, spontaneity, and chemical equilibria of various types. While the course still emphasizes mathematical problem-solving, it is much more conceptual in nature than the material covered in CHM 157. Accordingly, it is crucial that students stay current with the class material and ask questions early to clarify any confusion. CATALOG DESCRIPTION: Integrated lecture-laboratory. Chemical reactions, kinetics, equilibrium, acid-base chemistry, thermodynamics, electrochemistry. COURSE PREREQUISITES: CHM 144 and 147 or CHM 157. COURSE OBJECTIVES: Students will be able to: 1.

Understand the concepts of entropy and free energy and predict the spontaneity of a reaction using appropriate thermodynamic data.

2.

Analyze the factors that influence the rate of a chemical reaction both qualitatively and quantitatively.

3.

Apply principles of chemical equilibrium to calculate concentrations of reactants and products for several classes of chemical reactions, including acid-base reactions, precipitation reactions, and electrochemical reactions.

4.

Describe acid-base reactions both qualitatively and quantitatively.

5.

Understand electrochemical reactions both qualitatively and quantitatively.

COURSE POLICIES ATTENDANCE: The lecture/recitation portion of this course meets for about five (5) hours each week, four (4) hours of lecture and one (1) hour of recitation. I expect you to attend ALL scheduled lectures and recitation sessions. Material presented in lecture will supplement the text and round out your understanding of the concepts and problem-solving techniques necessary for success in chemistry. In the event that you miss class, you should check first with your fellow students to obtain notes or other missed information. Recitation sessions will be used primarily for additional practice and application of the concepts and for student-driven questions. If necessary, new material may also be presented during recitation. Failure to attend class, including recitation, limits your ability to be successful in this course and absences are highly discouraged. CLOSING OF THE UNIVERSITY: In the event that the University closes on a day when class is held forcing the class to be cancelled, the scheduled events (e.g. an exam) for the cancelled class day will be conducted at the next meeting. CLASSROOM ETIQUETTE: You should be on time for class and have attended to your needs before entering the room. Students who come late or who leave the classroom during class are a distraction to both the instructor and other students. The use of cellular phones or other electronic devices is also a distraction. Please ensure cellular phones are off (or on silent alert). If an emergency arises, please be courteous to your fellow students and leave quietly! E-MAIL ANNOUNCEMENTS: Class announcements will often be distributed via E-mail messages to your Oakland University student E-mail account in order to reach all students, regardless of their class attendance. It is your responsibility to check your Oakland University E-mail account frequently to keep current on course information. MOODLE: Moodle is the electronic classroom support system used at Oakland University. You will use this system to view course materials such as lecture notes (posted before class so you can print them to take notes if you like), chapter review sheets, solution keys, and other course information. You will login to Moodle at http://moodle.oakland.edu using your Oakland University E-mail username and password. ACADEMIC CONDUCT POLICY: Cheating on examinations, plagiarism, falsifying or copying another person’s data on lab reports, falsifying records, and unauthorized collaboration on computer assignments are examples of serious breaches of proper academic conduct. It is your responsibility as a member of the academic community at Oakland University to be familiar with and adhere to the “Academic Conduct Policy” published in the course catalog (under the “Academic Policies and Procedures” section). Students found guilty of academic misconduct by the Academic Conduct Committee will receive a course grade of 0.0 (this includes both the lecture and lab portion of the course). ADD/DROPS: The University add/drop policy will be explicitly followed. It is the student’s responsibility to be aware of the University deadline dates for dropping the course. SPECIAL CONSIDERATIONS: Students with disabilities who may require special considerations should make an appointment with campus Disability Support Services to complete the required paperwork. In addition, students should notify the instructor as early as possible about their needs, so that proper planning can be made in a timely fashion.

COURSE COMPONENTS & GRADING ONLINE HOMEWORK: Electronic homework assignments will be posted at the publisher’s website: http://smartwork.wwnorton.com. The assigned “enrollment code” for this course is: CHEM32191 (case-sensitive). Each assignment will cover one or two chapters and will be worth 25 points. It is your responsibility to be aware of the due dates for assignments. Do not wait until right before the due date to start an assignment. You should anticipate your work/school schedule and computer access and plan accordingly. You may attempt each question up to five times with your final answer graded. Your grade will be based on your percentage score for the best 7 out of 8 assignments (i.e., the lowest score will be “dropped”). TEST-TAKING PROCEDURES: All examinations will be of the closed book type. If any charts or tables are required, they will be provided with the printed exam. Students must bring a Scantron form to each exam (882-E type). Please note that the only calculator allowed for exams in chemistry classes are the TI-30X or TI-36X calculators. Also note that you may not borrow or share calculators during an examination. In addition, cell phones and/or any other electronic devices other than a TI-30X or TI-36X calculator must be turned off, stored, and not visible during exams. Once the exam begins, students will not be able to talk to each other, wear items which conceal their eyes (e.g., brimmed hats, sunglasses, etc.), leave the room, or look at their cell phone during an exam. Objections to this policy should be brought to the instructor’s attention during the first week of classes. HOURLY EXAMS: Three examinations will be administered during class time on the following dates: February 2, March 8, and April 5. Students may request at least one week in advance via E-mail an alternate time and location to take an exam for a legitimate conflict. Granting such requests is left entirely up to the instructor’s discretion and will only be done in extreme circumstances. If a student misses an exam due to an unforeseen emergency, that student must contact the instructor within 24 hours of the missed exam. In that situation, the instructor may choose at her discretion to schedule a make-up exam. There is no guarantee that any make-up exam will be identical in terms of content or difficulty to the missed exam (e.g., it may not be multiple choice and you may have to show all your work in order to get credit). NOTE: If you achieve a higher % score on the cumulative Final Exam than one of your previous 3 exams, the final exam % score will replace your lowest exam % score. FINAL EXAM: The date for your course’s comprehensive final exam will be the time posted by the University. For this course, the exam is scheduled for Tuesday, April 24, 8:00 - 11:00 AM in our normal classroom location. LABORATORY: All students must register for one of the laboratory sections. If you are repeating this course, you may be able to waive the laboratory portion of the current course. You may choose to use the laboratory scores from the first course if: (1) your average in the laboratory portion of that course was at least 75% and (2) you were enrolled in that course no more than three years ago. If you wish to apply for a laboratory waiver, you must complete a General Chemistry Laboratory Waiver form. These forms are available in the Department of Chemistry office, 260 Science and Engineering Building (SEB) or can be downloaded from Moodle (lecture course site). This laboratory waiver form must be completed and returned to your current lecture instructor during the first week of the current semester. You must attend the laboratory portion of the course until the waiver is approved.
