Chemistry 124B Course: General Chemistry Spring 2009 Professor: Dr. Jameica B. Hill Office: RMSC M306D; Phone: 4635 (O), 578-8416 (H) E-mail: [email protected] Office Hours: MW 1:00-2:00; T 9:00-11:00 Lectures: MWF 10:30-10:20 (RMSC 328)

Lab Assistant: Ryon Hamilton

Laboratories: W 2:00-5:00 (RMSC 311)

COURSE DESCRIPTION Chem 124 is a continuation of Chem 123. This course is designed to continue to give a general background in knowledge of chemistry, as well as provide the history and philosophy of the chemical sciences. In addition, students will have to be able to utilize a computer graphing program to produce standard curves. The instructional format is lecture/discussion and laboratory based. Course information may be found at http://webs.wofford.edu/hilljb/CHEM124/chem124.htm. REQUIRED • Lecture Text: Raymond Chang, Chemistry, 9th ed., WCB-McGraw-Hill. •

Chemistry Notebook (carbonless)

•

Basic, non-programmable, scientific calculator (TI-30Xa in bookstore)

RECOMMENDED Solutions Manual: Student Solutions Manual to Accompany Raymond Chang Chemistry, 9th ed., WCB-McGraw-Hill. Personal pair of safety goggles (in bookstore) GRADING SCALE Final grades will be assigned according to the following score range: 93%-100% A 90%-92% A87%-89% B+ 83%-86% B 80%-82% B77%-79% C+ 73%-76% C 70%-72% C60%-69% D < 60% F This average will be based on four exams, the laboratory grade, the final exam, and short class quizzes (best 5 of 6) and homework assignments (best 5 of 6). Course grades will be apportioned as shown below: Exams 50% (12.5% each) Laboratory 20% Final Exam 10% Class Quizzes and Homework 20% 100% The final exam grade will substitute for your lowest exam grade of the semester (except for a zero) if it is to your advantage and you make 70% or better on the final exam. NOTES 1. Makeup exams will be given within one week following the scheduled exam to students with a valid excuse (given prior to scheduled exam). If an exam is missed and no makeup is scheduled within a week of the missed exam, or the final exam is missed (no makeup), a course grade of F will be recorded. Quizzes cannot be made up. Late homework is penalized 10 pts/day. 2. If a student needs special accommodations due to a disability, notify Dr. Hill immediately. 3. Attendance in lectures is expected (reference the Student Handbook: http://www.wofford.edu/uploadedFiles/studentLife/0708StudentHandbook.pdf). Laboratory allows for no unexcused absences! Any unexcused absences in lab will result in an F for the course. 4. Extra credit opportunities will be available as noted by Dr. Hill. Other opportunities will only be allowed in an Honors situation (reference Catalogue). Extra credit implies that the basic material required on this syllabus has been mastered. 5. Students are expected to govern themselves by the Honor Code (http://wofford.edu/uploadedFiles/studentLife/0708HonorCode.pdf).
