1 Chemistry 102: General Chemistry II Section 2, Spring 2010 Monday, Wednesday, & Friday: 11:00-11:50 in Chapman 211 Professor: Domenic J. Tiani, Ph.D. Office: Kenan B128 I will respond to questions within 24 hours. OFFICE HOURS: Mon. 3:00 4:00, Tues. 9:30-10:30, and Thur. 12:00 1:00 in Kenan B128 or by appointment. You may also stop by my office anytime and if I am available, I will talk with you. Please, if you need help and you cannot make my office hours, me and set up another time with me. CLASS WEBSITE: The website for this class is located at http//blackboard.unc.edu. You will need to check this site daily for any new class announcements. I will also use this site to post a variety of other course information and material: course syllabus, reading assignments, problem assignments, articles, exam keys, useful websites, and grades. PREREQUISITES: Chemistry 101 (C- or better) and 101L. REQUIRED TEXTBOOKS Chemistry: The Central Science, 11 th ed., Brown and LeMay. Solutions to Red Exercises to Accompany Chemistry: The Central Science, 11 th ed., Roxy Wilson. NOTE: You will not need an access code for OneKey. We will not be using any of the textbook resources that require this access code. EQUIPMENT: Two scientific calculators that you know how to use. Most students have a good scientific calculator (TI-XX). I recommend that you also purchase a less expensive basic scientific calculator as a back-up. Bring a back-up calculator and extra batteries to all classes and exams. You will not be allowed to share calculators and cellular phones will not be allowed to be used as a calculator. ATTENDANCE: In large lecture classes such as this, it is not possible to take attendance on a daily basis. Although I do not take attendance, I expect you to attend all lectures. Past experience shows a strong correlation between performance and class attendance. There will be material presented in class that may not be in your text, you are responsible for knowing this material, regardless of whether you were present in lecture or not.

2 Punctual (i.e., on time) classroom attendance is required. Arriving late to class is distracting, rude, and inconsiderate. Please be on time for all classes and exams. On Exam days you will not receive additional exam time if you are late. GRADED HOMEWORK (MasteringChemistry) A total of 11 graded homework assignments will be given throughout the semester, the dates of which are listed on the class schedule at the end of this syllabus. This class will use MasteringChemistry for the graded homework assignments. The MasteringChemistry site is located at There is also a link in your Blackboard site that will take you directly to this site. We are fortunate to have the opportunity to use this site in the spring free of charge, so you will not be charged any fee. This is only for the spring 2010 semester. I will all of you an instruction sheet that contains all the information you will need to register and login to the MasteringChemistry website. This instruction sheet is also located on Blackboard under the Handout tab. IMPORTANT: I am teaching two Chemistry 102 sections this semester. It is important that you use the correct Course ID that I provide you because each of my sections has a different Course ID. If you drop one section and add another section of Chemistry 102, please your instructor and let them know. We have to take you off our MasteringChemistry roster so that your new instructor can add you to their roster. Go to the MasteringChemistry site and enroll as a new user by following the instructions on the handout I ed the class. Complete the Introduction to MasteringChemistry assignment by 5:00 pm on Friday, January 15 th. This is not an optional assignment and must be completed. Graded assignments will become available on Friday mornings at 12:00 pm and be due Monday mornings by 12:00 pm. No late assignments will be accepted. The MasteringChemistry clock will be used in deciding if an assignment has been completed on time. This clock may differ from your computer s clock, your dorm clock or your watch, so DO NOT wait until the last minute to complete and submit your graded assignments. All graded assignments are to be worked on independently, with no outside help of any kind: fellow students, friends, teachers, TAs. Any collaboration will be treated as a violation of the student Honor Code and will be handled accordingly. ASSIGNED TEXTBOOK HOMEWORK PROBLEMS At the start of each new chapter a set of problems from the end of the chapter will be assigned for you to work. The red problems will typically be assigned because you can check the answers to these problems in your solution manual. The assigned textbook problems are not graded. These problems are meant to provide you with practice and to help illustrate the concepts we are discussing in class. It is

3 your responsibility to work as many problems as necessary in order to feel comfortable with the material. Work the black problems if you need extra practice or want to test whether you understand the material. I have the solutions to all the textbook problems. You may come to my office to check your answers to the black problems. All assignments will be posted on Blackboard under the Assignment tab. The best strategy for learning the material is to try and work the problems without the aid of the solution manual. If you consistently need the solution manual to work the problems, then you do not understand the material as well as you may think. Pay attention to how long it takes you to work through problems; if it is taking you a long time or if you find yourself very reliant on your notes, textbook or solution manual, then you do not understand the material as well as you may think. EXAMS & GRADES The letter grades for the course will be based on your overall percent score from three 50 minute exams throughout the semester (100 points each), the best 10 graded homework assignments, and a final exam. Each of these areas are weighted as follows: 3 Exams (20 % Each) 60 % Best 10 Graded Homework Assignments 10 % Final Exam 30 % Total 100 % Three 50 minute exams will be given throughout the semester on the following days: Exam 1: Wednesday, 2/10 Exam 2: Friday, 3/5 Exam 3: Wednesday, 4/14 The Final Exam is cumulative and is scheduled for Monday, May 3 (12:00 3:00 pm) in Chapman 211. There will be no make-up examinations except in the event of extraordinary circumstances such as serious illness, accident, or family emergency. The letter grades for the course will be determined based on a student s overall percentage and will be assigned using the cutoffs provided in the table below: Final Average Letter Grade A A B B B-

4 74-79 C C C D < 50 F HONOR CODE: Policy adopted by the faculty of the Department of Chemistry on Sept. 9, 1977: Since all graded work (including homework to be collected, quizzes, papers, mid-term examinations, final examinations, research proposals, laboratory results and reports, etc.) may be used in the determination of academic progress, no collaboration on this work is permitted unless the instructor explicitly indicates that some specific degree of collaboration is allowed. This statement is not intended to discourage students from studying together or working together on assignments which are not to be collected. CLASS SCHEDULE: Below is a tentative class schedule for the semester. You should note that this schedule is subject to change. Any changes will be announced ahead of time in class.
