1 Georgia Perimeter College - Dunwoody SYLLABUS 1/05/2011 CRN # CHEM PRINCIPLES OF CHEMISTRY II Spring 2011 Class Time: M W 8:30-9:45 AM Lecture Room: NE-0300 Instructor: Prof. Myung-Hoon Kim Office: NE-2222, (770) , Myung.Kim@gpc.edu Office Hrs: M T* R*1:30-3:30pm (*at LTC); W 10:30-12:30pm; F 12:00-2:00pm Website: facstaff.gpc.edu/~mkim Objective: To acquaint students with fundamental principles and topics of chemistry. Description: This is the second course in college chemistry for those whose majors or areas of interest are in science/engineering. This course is also the appropriate course for pre-medicine, pre-dentistry, prepharmacy, and physical therapy. It is not the normal choice for those going into nursing, dental hygiene, and several other allied health sciences. Areas of emphasis include solutions, reaction rates, chemical equilibrium, acid/base reactions, thermodynamics, and electrochemistry. Requirements: CHEM 1211 with a C or better is a pre-requisite. The student must have evidence in the form of a grade report or a transcript that this prerequisite has been met. CHEM 1212L lab is a co-requisite. Textbook & Materials: Chemistry (8th ed., Zumdahl/Zumdahl, Brooks/Cole, Cengage Learning, 2010) and OWL (an onli ne homework system, are required (Course ID: Kim CHEM 1212 Spring 2011). A scientific calculator is recommended. Attendance: Students are expected to attend all class meetings. In the event of absence it is the students' responsibility to obtain assignments and information covered during the absence. A grade of W will be assigned if the student officially withdraws by mid-point. After mid-point withdrawal will result in a F grade unless a hardship waiver is granted by the department head. It is the student's responsibility to complete withdrawal through the registrar's office in the event that becomes necessary. Withdrawal from lecture automatically requires withdrawal from the lab and vice versa. A roll sheet will be circulated at the beginning of class. A student who arrives late should stop by at the end of class and sign it. Topics of a missed class, due to school closing from inclement weather (tune to WSB, AM 750 khz, or Channel 2), will be automatically assigned as a take-home project. Tests: There will be four class tests and a final exam. The final exam is required. There are no make-up tests. The final course grade is obtained by averaging the three highest class exams, MasteringChemistry and the final which weighs twice of the hour exams. If one of the class exams is missed, that exam becomes the dropped exam. The grading scale is the standard scale with = A (Excellent), = B(Good), = C(Fair), etc. Three Best Hour Exams: 3 Exam x 100 pts/exam = 300 pts OWL (Online Homework): 10 Chap x 10 pts/chap = 100 pts Final Exam: = 200 pts Total 600 pts. A. Each Hour Exam consists of about 30 Multiple Choice Questions and 1-2 big Write-Out Questions. Sources: (1) Textbook (the Sample, Practice, & EOC Exercises) and Lecture Notes ( ~70%), (2) Applied questions (~30%) B. Bring #2 pencils and the Scantron Forms (882). (Note: An old mark must be completely erased). C. Extra points: 15 pts for a good attendance; Catching mistakes, 1~3pts/catch (max.: 15pts). 1

2 Time requirements The amount of time outside of class needed to be successful in this class varies with background, interest, motivation, intellect, and study skills. To be successful, expect 6 or more hours per week outside of class to study and do homework. Students must develop skill in solving problems and this can only be obtained by practicing and doing homework. The lab grade is separate and requires additional time. Expect 3 to 6 hours to prepare for lab sessions, calculate results, and prepare reports. Careful attention and good time management can reduce the time required outside of class. Disruptive actions: Students are expected to act with respect for a professor and other class mates. Arriving late for class can be disruptive. In the event of a late arrival you enter and take a seat quietly. Talking to others during lecture/discussion prevents others from hearing the proceedings. Leaving class during session is very disruptive and should occur only in an emergency. Food and drink are not allowed in the classroom.- Cheating and Plagiarism: Refer to the Green Handout for Academic Honesty Policy and others. Incomplete: An incomplete (I) grade is for special situations. If a student misses the final exam due to illness, or other special circumstance, request an I grade can be petitioned. Documentation is required confirming the difficulty. The I grade must be made up within one semester.
