1 Chemistry 102 General Chemistry Spring 2012 Professor Farah Firtha Description: This class is a continuation of Chemistry 101. Special emphasis is given to chemical kinetics and equilibrium, thermodynamics, acid- base equilibria, electrochemistry, common reactions of metals and non-metals with an introduction to qualitative analysis. Office Hours: Office-LRC 806. Hours- M 12:30-1:30pm. Tue 9:30am-12:30pm. W 12:30-1:30pm. Also by appointment and after class. You are encouraged to meet with me if you have any questions regarding the lecture, homework, tests, labs, or your performance in the course. When you contact the instructor please use Chem 102 in the subject. s without this subject may be overlooked. Prerequisite: Chemistry 101 Requirements: You must have an active account for this class. If you do not the college can issue you one and you may use the computers in the library to access your account. You may also need to gain access to Blackboard for course material at my.msjc.edu Blackboard allows you to easily communicate with your instructor and fellow students. I will post power-point lectures and handouts on blackboard usually under course documents; you can find your current points on blackboard under tools; important announcements can be found on the home page of blackboard. If you took math or chemistry awhile ago I suggest watching videos on Khan Academy.org to refresh your memory. Resources: Khanacademy.org a free university sort of. You tube video lectures on many topics including chemistry. Mastering chemistry if you bought the book new then you have access to this website. It has more quizzes and other helpful resources. Smarthinking an online tutoring (usually 24/7), yes they have chemistry. You can access this in blackboard under tools. Texts: Chemistry: A Molecular Approach, Nivaldo J. Tro. 2 nd ed. Chemistry 102 Lab Manual, Mary Bodo Chemistry Study Guide, Nivaldo J. Tro. Recommended Supplies: A non-graphing scientific calculator, closed-toed shoes and safety googles. Lecture: T TH 12:30-1:50pm Room 304. Attendance is required to succeed in the course. Each lecture has a discussion component or demonstration and may be more in-depth than the material presented in the text. If you must miss a lecture, please inform me beforehand, if possible, and copy the notes from a member of your study group. You are responsible for any information you missed. In general, late work is not accepted and missed assignments cannot be made-up.

2 Laboratory: T TH 2-5pm Room 306. Laboratory is an integral part of the course; it is important to arrive on time as important safety information and demonstration of procedures may take place at the beginning of the lab period. If you are late, you may not be able to perform the experiment and will receive a zero for that laboratory. The experiments are designed to enhance and extend your understanding of concepts discussed in lecture and students should read the assigned experiment before the lab meeting. Students must attend lab and cannot receive credit by borrowing experimental data from others. Usually, lab reports are due at the end of each lab period and the pre-labs or assignments are due at the beginning of the lab period. Work due during a lecture or lab time is late at the beginning of the assigned period. In general, late work is not accepted and missed labs cannot be made-up. Please meet with me to discuss any situation that may arise that will preclude your attendance. I am in the lab to help you, but I will not do the lab for you. You must do the laboratory, the lab report, and the pre-labs to receive credit for each lab grade. CAUTION: Lab partners may share data, but they are not allowed to turn in the same lab report. Any student who misses more than TWO labs may be automatically dropped from the course or given a failing grade. The lab portion of your grade is calculated after dropping the one lowest lab grades of the semester. Most labs are worth 15 points. Two-day labs are worth 25 points and QUAL IV is worth 35 points. Points will be deducted if lab groups become greater than 3 students. Lab safety: You are required to wear safety glasses, closed toes shoes and attire that protects your legs. I reserve the right to dismiss you from lab if you do not wear the proper attire and you will receive a zero for that lab. COME PREPARED. Study: The main point of this course is to guide your development of critical thinking processes as they pertain to the study of Chemistry. For you to succeed in this course you must practice the concepts covered and prepare for each class. Before each lecture, read the material to be covered. Do not spend too much time on any one point; simply obtain an overview of the relevant topics to be covered. After lecture, reread the material more critically referring to your notes for difficult concepts. Try the assigned exercises and review at the end of each chapter. You may want to wait a day or more after reading the chapter to attempt the exercises in the back of the chapter. Waiting will test your retainment of the material. Discuss the concepts and exercises with your weekly study group. If you have trouble with a particular concept or assignment, ask for help in class or come to my office. You are encouraged to utilize the facilities available on campus including the Learning Resource Center. Do not try to just memorize material. THINK about the material!! Does the material make sense? Is the material related to what you already know? Many concepts or problems may seem difficult, but are rather simple when related to what you already know. Tests: There will be FOUR, 100 point tests during the semester and a comprehensive, 200 point final exam. Missed tests cannot be made-up and every test day will be announced the first week of class. All test questions are based on lecture, assigned reading, homework and laboratory work. Missed tests cannot be made-up unless arrangements are made with the instructor PRIOR to the exam date. Arrangements may be made in person or by phone. However, phone messages are not acceptable. It is the responsibility of the student to get in touch with the instructor. Every test day will be announced the first week of class. These tests are closed book. During the test no cell phones or PDAs can be in use. There will be no trips outside the classroom during the test so plan accordingly. Do not wait until the day before the exam to study the material. There will be POP quizzes throughout the semester, so always study the material.

3 Quizzes: There may be a quiz or a test almost every week. Quizzes will be based on assigned homework and lecture material. If you have completed and understood the homework and practice problems in class, the quizzes should be straightforward. Participation Points: Book Homework: Homework may be periodically collected. You will be given a one day notice of collection Projects/ Assignments: There will be various assignments through-out the semester. Student Behavior: A student who has not attended class for a total of 4 class meetings may be dropped from the class. Any disruptive behavior, including cell-phones and beepers, will not be tolerated in class and may result in dismissal from the class. During Exams, everything must be removed from your surrounding area. You will be required to put your backpacks and notebooks in the front of class during the exam. A student cheating on any assignment, including plagiarism, will receive a zero on that assignment and may be referred to a disciplinary hearing and/or receive an F in the class. Also, it is the student s responsibility to withdraw from class. HOW TO TURN IN ASSIGNMENTS: please SEPARATE each assignment into piles. You may receive a zero on an assignment if I did not see it because it was stapled to another assignment. Assignments are due at the beginning of the classes. Pre-lab assignments are due at the beginning of the class. Lab reports are due at the end of the lab period. Grading: A ten-point scale will be used for grading as shown below: A: %, B: 80-89%, C: 70-79%, D: 60-69%, F: Below 60%. POINT SUMMARY TEST points 16 graded labs = 320pts total TEST points Participation/ Hwrk/ Pop quiz points=80pts TEST points TEST points Final Exam = 200 points Scores above = 400 points It is the responsibility of the student throughout the semester to maintain knowledge of their current grade. In order to receive a grade of C or better, your overall lecture average (tests, quizzes and final exam) must be higher than 65%. Even if your overall average (including labs and extra credit) in the class is 70% or better, if your lecture average is less than 65% you will receive a D letter grade. This syllabus is subject to change without notice per the discretion of the instructor. A Few Support Services (there are many more available on campus)
