Final Exam: Tues., May 8, noon - 1:55 PM in MGH 111 Themes for the semester:! Chemical reactivity. Principles I focused on the structure of atoms and molecules; now we will focus on chemical change.! Chemistry beyond molecules. How molecules combine and arrange themselves to form bigger things, such as macromolecules, solutions, colloids, and materials.! The chemistry of biology. I will use examples from biology to illustrate the course concepts.! How do we know? The nature of the scientific method. To get ready, review the material of Principles I, especially chapters 9 and 10. If you like you can get started on Assignment 0 using WebAssign (see next page for instructions). Assignment 0 reviews some relevant material from Principles I. As a student in Chemistry 153, Section 002, you are responsible for knowing the policies and procedures for the course contained in this document. Chemistry 153, Section 002 page 1
Material and Resources Text: Principles of General Chemistry, 1 st ed slim OR Chemistry - The Molecular Nature of Matter and Change 4 th ed (or 3 rd ) thick Each is by Martin S. Silberberg and published by McGraw-Hill. Either text is fine for this course and the core material is identical in the two books. Most students will have one of these from Principles of Chemistry I. The slim text has fewer applications and problems and has a lower list price. If you need to buy a text, check the prices carefully locally and on the web. For used texts, the thick version might be cheaper from some vendors. The Chemistry Department will provide the WebAssign access code that you will need for on-line homework assignments, so you don't need to buy an access code. Other Required Materials:! A "clicker", formally known as an einstruction CPS RF personal response pad. A clicker that you used in Fall 2006 is OK. The same clicker will work in all your UA classes that use clickers. The campus bookstore has used clickers like the one pictured at left, and will have a new model, which will also work. The class key is H24982C221. Find detailed instructions about how to enroll your clicker for this course on the course web site (see below).! A scientific calculator. Calculators used in math courses through 3450:223 should be fine. Note that devices with a QWERTY keyboard may not be used during quizzes and exams. On-line Assignments! Weekly assignments are posted and scored on the web at http://webassign.net/ Your WebAssign Username is your uanetid. (NO @uakron!!) Your institution is uakron. Your initial password is your UA student ID number (7 digits).! Assignment 0, due on Tuesday, Jan. 23 at 7:00 PM, is a review of useful material from Principles I.! Each on-line assignment will be posted on WebAssign with the due time and instructions. Course Announcements! Will be posted on WebAssign. Course Web Site!

Attendance and Participation Principles of Chemistry II Course Policies and Procedures You are expected to attend and participate in all lectures. Attendance is recorded using the CPSrf response pads. You are responsible for all information, including assignments, policy changes, schedule changes, etc., announced in class whether you are present in class or not. Participation includes answering questions with your clicker, asking questions, and participating in discussions. Participation credit is based on whether you responded to the questions, NOT on whether you got the right answer. Participation and attendance will be graded on a 40% to 80% scale. That is, a student who responds to 80% or more of the questions during the semester will get 100% of the participation credit, but a student who has responded to less than 40% will get zero participation credit. Students between these limits will get a prorated score. Homework Assignments Much of the learning in this course will occur while you are doing the homework assignments. The homework will give you a good idea about the kind and level of questions to expect on the exams. On-line homework assignments will be assigned weekly on WebAssign and will include readings from the textbook. You can do the on-line homework in the computer lab KNCL 314 or anywhere that you have internet access. Problems in the online homework sets come mainly from the textbook end-of-chapter problems, but some are from elsewhere. On-line homework sets must be completed by 7:00pm on the due date to receive credit. The computer lab KNCL 314 will be open in the hours leading up to each deadline so that you can get help. Don t expect the TA to do the problems for you, but he or she can help you with the concepts or help you find mistakes. Extensions cannot be given. Some assignments will require longhand written answers to help students learn how to present solutions to problems. Your three lowest homework scores will be dropped from your final course total. Mid-term Exams Three exams containing both multiple choice and written questions will be given in class. Each of the exams will start at the beginning of our regular class period. The lowest of the three-hour exam scores will be replaced by the final exam score, if that score is higher. Exams missed for excused reasons with appropriate notice will be replaced with the final exam score. Exams missed for unexcused reasons will be recorded as a zero. A seating plan will be posted before each exam. Sit in your assigned row with an empty chair between you and the next student. Bring pencils, calculator, eraser, and Zip Card ID to each exam. Do not wear a hat with a brim. If you want to wear a baseball cap turn it so that the brim is at the back. Do not arrive more than 20 minutes late to an exam. No one will be allowed to leave during the first 20 minutes of the exam. After that, you may leave when you wish but do so quietly to avoid disrupting the work of other students. No one will be allowed to enter and begin the exam more than 20 minutes after the exam has begun. You may be required to erase the memory register of your calculator at any time before or during exams and quizzes. Palm devices, cell phones, and devices with a QWERTY keyboard are Chemistry 153, Section 002 page 4
not acceptable for use during exams or quizzes. Each student is responsible for bringing his/her own calculator to each exam and quiz. Sharing of calculators by students is not allowed during exams. Comprehensive Final Examination Course Credit The final exam will be cumulative over all course material. The rules are the same as for the hour exams. Homework 8% Attendance/Participation 4% 3 Hour Exams (22% each) 66% Comprehensive Final Exam 22% TOTAL 100% Course grades will include + and - grades. I do not have a fixed correspondence between numerical scores and letter grades, but I will post an approximate grading scale after each exam so that you will know how well you are doing in the class. I include a small number of more challenging problems in each exam, so generally I require fewer points for each letter grade than some other instructors. Withdrawal from the Course Jan. 3. Mar. 9. Apr. 13. Academic Integrity Last day to withdraw from Spring Semester 2006 without advisor s signature. Last day to withdraw from Spring Semester 2006 without instructor s signature. Last day to process course withdrawals for Spring Semester 2006 (5:00 pm). Violations of the Academic Integrity code include plagiarism, cheating, and other forms of academic dishonesty. The minimum penalty for violations of this policy is a grade of F in the course. In addition, University policy states that formal disciplinary probation, suspension, or dismissal may also occur. Students with Disabilities Students with disabilities should visit the UA Office of Accessibility in Simmons Hall room 105 (or call 330-972-7928) to determine what kind of academic accommodation you need. The Office of Accessibility will give you a form that states the needed accommodations and then you can bring that form to me so that arrangements can be made. Classroom Courtesy Please turn off beepers and cell phones in class. Your UA e-mail account is essential in this course. If you do not use this account, set it up to forward messages to an account you do use. Sign all e-mail messages at the bottom, so that I know who has sent the message and can reply to you. E-mail is great for short communications and for sharing information, but I can t give extra help by e-mail. It is best to meet face-to-face for extra help; just stop by my office or make an appointment. Arriving late/leaving early? Please use the back doors and sit near the back of the room.

Strategies for Success! Attend lectures and participate. Even one missed lecture can make you feel lost at the next lecture. If you do miss a lecture because of an unavoidable circumstance, get the notes from a classmate and read the relevant section of the text before the next lecture.! Work all of the assigned problems and possibly others from the textbook. Remember that the problems and the in-class questions give you a measure of what will be on the exams.! Read the relevant sections in your textbook before and after lectures and while doing homework problems.! Discuss the material and work through problems with others students. Form a study group!! Get help when you need it. Make use of the TA s in KNCL 314 and of me, your instructor.! Don't get behind!! Start homework early while there is still time to get help before the deadline. If you have a problem, get help right away. The course mores quickly. If one topic is a mystery, the next topic, which depends on it, will be even worse.! Review your exams after you get them back. I include a couple questions from the last exam in the next exam, usually the ones that caused people the most difficulty.! Don t get discouraged! It is common to have trouble with parts of the material, but it is what you know in the end that counts. The grading scheme is forgiving in that it will let you mess up early on but still earn a good grade if you have mastered the material by the end of the semester.! If you are not able to put in the consistent effort to do these things, then consider dropping the course now. For most people, this means at least 6 hours of private study per week in addition to the lectures. Ohio Board of Regents Transfer Assurance Guides (TAG s)! The Ohio Board of Regents has established guidelines for the content of lower level courses in each major so that students may transfer credit easily between colleges. These are called TAG s and can be found at http://regents.ohio.gov/transfer/tags/.! Here are the specified learning outcomes for this course. Students must be proficient in all of the following core competencies: 1. Intermolecular forces and phase changes 2. Solutions and colligative properties 3. Chemical kinetics 4. Chemical equilibrium 5. Acid-base equilibria 6. Thermodynamics (including entropy and free energy) 7. Electrochemistry 8. Descriptive chemistry, including chemical properties and classification of the elements, periodic patterns of reactivity 9. Students should have been exposed to a variety of applications of chemistry in society 10. Students must have continued to develop strong analytical and interpretive skills to effectively apply algebraic methods to solve chemical problems. Chemistry 153, Section 002 page 6
