Textbook: Introduction to Chemical Principles by Stephen Stoker, 10 th Edition, Prentice Hall, 2010 Laboratory Manual: General Chemistry: CHE 107 Lab Manual Nassau Community College Edited by Douglas S. Cody and Edward R. Shenal, 3rd Edition, Thomson Learning Custom Publishing, 2003 Course Website: The lecture notes and any documents given out in class can be downloaded at: http://faculty.ncc.edu/hicksc I suggest you read the lecture notes and attempt the problems before coming to class. Announcements: Check your email daily for announcements distributed via email. Attendance: When you arrive for lecture mark yourself present in the spreadsheet in my laptop. Exams/Grading: There will be four exams worth 15% each. Exam questions will be based on the assigned homework problems and the problems worked out in the lecture notes. To prepare for the exam you should do all the assigned homework problems and the problems in the notes. Homework will account for 15% of the grade. The laboratory will account for 25% of the grade. Course Total = 60% Exams + 15% Homework + 25% Laboratory A=90-100 B + =85-89 B=80-84 C + =75-79 C=70-74 D + =65-69 D=60-64 F<60 Homework: All assigned homework problems must be done in a loose-leaf notebook. Each problem should clearly indicate the chapter and problem number. If the problem involves calculations of more than a single step substantial work must be shown to receive any credit. Simply copying the answer from the solutions manual with no work shown will result in a grade of zero. The homework notebook will be collected at the beginning of each exam. One homework problem will be selected for grading on each occasion the notebook is collected. The average grade on these four problems will determine 15% of your grade in the course. Class Days: Bring your homework notebook, a calculator, and your copy of the notes to every lecture. Academic Integrity: Absolutely any form of academic dishonesty is grounds for failure in the course

NASSAU COMMUNITY COLLEGE Department of Chemistry NASSAU COMMUNITY COLLEGE Department of Chemistry DEPARTMENTAL POLICY CONCERNING SAFETY EQUIPMENT IN THE LABORATORY All students and faculty are required to use the following protective equipment when working in the chemistry laboratory: I. PROTECTIVE EYEWEAR: Individuals working in a laboratory environment must wear chemical splash goggles that include: 1. An optically clear lens, which meets ANSI Z87.1, impact requirements and has antifog coating. 2. INDIRECT AIR VENTS designed to restrict the entry of liquids and small particles. Individuals who normally wear prescription glasses must: 1. Wear the splash goggle described above over their prescription glasses. OR 2. Wear prescription glasses equipped with frames having SIDE, TOP and BOTTOM splash protection. Lenses must meet ANSI Z87.1 impact requirements. 3. Contact lenses are not recommended in a laboratory environment. The splash protection goggle described above MUST be worn with contact lenses. II. PROTECTIVE CLOTHING: 1. Individuals working in a laboratory environment are required to wear a laboratory coat (with front closure) that is long enough to provide approximately knee-length protection. BE ADVISED: There is some evidence that protective clothing made of 65% Dacron polyester/35% cotton may increase the severity of burn injury if the garment should catch fire. We therefore strongly recommend the use of cloth protective garments made of 100% cotton rather than a polyester/cotton mix. 2. Outerwear such as coats, jackets, sweatshirts, or sweaters DO NOT meet this requirement. Shorts, open-toed shoes, and sandals are NOT permitted.
Withdrawal Policy: Requests for withdrawals after the deadline set by the college will be considered on a case by case basis. If you take the final examination a withdrawal will not be considered and you will receive a grade in the course. If you are absent from the final exam for absolutely any reason you must contact me within 24 hours of the exam to explain your absence or you will receive an F in the course. Special Needs "If you have a physical, psychological, medical or learning disability that may impact your ability to carry out assigned coursework, I would urge that you contact the staff in The Center for Students with Disabilities (CSD) in Building "U", 572-7241, TTY 572-7617. CSD will review your concerns and determine with you what accommodations are necessary and appropriate. All information and documentation is confidential." Examination Rules: All cell phones must be silenced. No cell phone use during the exam. No papers except those distributed with the exam may be used. Scrap paper will be provided upon request. No sharing calculators. No bathroom breaks without a doctor s note describing a medical condition that makes necessitates frequent use of the restroom. All students must complete the exam, including the transfer of answers to the scantron forms, in the allotted time regardless of their time of arrival. The exam will not be given to any student that arrives after the first student completes the exam and leaves the exam room. Use of a writing utensil after announcement that the exam has ended is grounds for awarding a zero on the exam. Any request for consideration of re-grading of an exam must be submitted in writing with the exam paper.
