2 Evaluation Midterm 30% Report 20% Final Exam 50% Two problem sets: Un-marked but answers provided Practice questions assigned after each chapter Midterm in class: February 12 th Exams will be closed book but equations will be provided! Office Hours: Wednesday 1:00-2:30 PM, others available upon request Dean s Note: Students who feel that there are reasons to review their grades should follow the steps set out in Regulation 13, Review and Appeal of Grades. Academic Dishonesty The Senate document on Academic Dishonesty states that "Plagiarism means presenting work done (in whole or in part) by someone else as if it were one's own." Plagiarized work could result in an automatic failure in any Chemistry course and a subsequent request to withdraw from the program. Students should consult the Senate document ( or talk to the course instructor when in doubt about how best to refer to the work of others. For the most recent version of Academic Regulation 12 (Academic Integrity), please check the web at Calculators for exams (Academic Regulation 9): Calculators acceptable for use during quizzes, tests and examinations are intended to support the basic calculating functions required by most Arts and Science courses. For this purpose, the use of the Casio 991 series calculator is permitted. Students may also use calculators with a Gold Applied Science approval sticker or a Blue Commerce approval sticker as they are considered to be comparable to the Casio 991. Calculators with advanced features or substantial text storage capacity are not permitted unless otherwise approved by the instructor. Communicating calculators are banned.

5 Chem 321 Report Guidelines Due Noon Friday March 18th, 2016 Write a report of no less than 7 and no more than 10 typed pages (figures included). Use 12-point font, 1" margins, and at least 1.5 spacing throughout. The topic of your report can be either one of those listed below or another with my approval. Your report should have a short abstract on the first page, with an absolute upper limit of 75 words. The report should contain a detailed introduction and description of your chosen analytical method or application. Further items to be discussed in your paper may include types of compounds analyzed, detection limits, chemical information obtained, sample preparation, instrument types and parameters etc. References should conform to normal conventions by number markings in the text, thus1; or the author s name and date of publication in parentheses (SMITH, 2008). Copying the work of another writer into your own work without acknowledgment constitutes plagiarism and will not be tolerated (see course details). Please turn in your completed report to my office, 305 Chernoff Hall (under door if I am not there) by noon Friday March 18th, (You can hand it in early, but you cannot be late). Late reports are subject to a 15 % /day late penalty. Student is required to submit both a paper and electronic version of their report. Detailed list of topics and more complete instructions will be posted on Moodle.

7 Chapter 22: Introduction to Chemical Separations IUPAC Definition of Separation: Separation is the hypothetical condition where there is complete isolation, by m separate macroscopic regions, of each of the m chemical components which comprise a mixture. In other words, the goal of any separation process is to isolate the m chemical components, in their pure forms, into m separate vessels, such as glass vials or polyethylene bottles.
