Dr. Christopher J. Nichols PHSC 308 Ph 898-5541 e-mail: cjnichols@csuchico.edu Internet: http://www.csuchico.edu/~cjnichols Office Hours W 9-10:30; Th 10-12; F 9-10:30 CHEMISTRY 112 SPRING 2013 General Chemistry (Part 2) Prerequisites Completion of CHEM 111 (or its equivalent at another institution) with a grade of C-minus or better. A grade of D in CHEM 111 is not acceptable for progressing to CHEM 112. Is this the right class for you? CHEM 112 is a required course for students in a variety of science majors (CHEM, BIOC, BIOL, MICR, GEOS, ENSC, PHYS). It also counts towards degrees in animal science and exercise physiology. It is required for entry into many pre-professional programs in areas such as medicine, dentistry, pharmacy, veterinary studies, and physical therapy. Waitlist All lab sections of CHEM 112 are full, and many have waitlists as well. If you are enrolled, you must be present at the first meeting of your lab section or you may be dropped from the class. If you do not show up within the first 15 minutes of your first lab section, and someone on the waitlist is there, you will be dropped immediately. Curriculum Chem 112 is the second of a 2-semester sequence (Chem 111 is the first part) of general chemistry for students in science and related disciplines. Chem 112 covers topics included in Chapters 12-17 and 20-22 of the McMurry/Fay textbook (plus a little bit from chapter 2). The topics are listed on the lecture calendar page. By the end of the semester you will have learned about concepts and calculations involving kinetics, equilibrium, acid-base chemistry, thermodynamics, electrochemistry, coordination chemistry, and nuclear chemistry. Important Note: CHEM 320 now has a prerequisite of completion of CHEM 112 with a C-minus or better. If you earn a grade of D in CHEM 112 you will not be permitted to progress to CHEM 320. Textbooks and Other Materials Required: "Chemistry" by McMurry and Fay (6th customized ed. for CSUC, 2012, ISBN: 1256160873). The regular 6 th edition will also work (ISBN 032174103X). Please do not get older editions. Required: Laboratory Experiments: Chemistry, The Central Science by Nelson, Kemp, and Stoltzfus (12 h ed., 2012). ISBN: 0321705025. Required: TurningPoint ResponseCard XR clicker, available new or used at the AS Bookstore. Materials for Lab (all are required) Safety glasses/goggles (SAACS will come around to lab and sell you a pair for approx. $7) Combination lock or padlock (SAACS will also sell you one for approx. $7) - 1 -
Homework Small (2-4 problem) homework assignments will be given almost every day, and will be due the following class. Homework is due in the correct homework bin in class: if it is not turned in during the class it will be considered late. Late homework will not be accepted: no exceptions. To help with grading the homework, please write in BIG letters on the top of the page the number of the assignment (i.e. HOMEWORK #6 ) and your name. Each HW assignment is worth 3 points (up to a maximum of 112 points for the semester). Blackboard Learn The Bb Learn site will be used for a calendar of assignments and to post answers to the homework, quizzes, and exams. You may also contact me with questions through the Bb Learn e-mail interface. Clickers You are required to purchase a TurningPointXR clicker (the standard one used by our campus) for CHEM 112. Every class day (except for exams and the first week) I will use them multiple times to get feedback from you to determine whether or not most students understand a particular chemical concept. I expect everyone to bring their clicker to class each day and answer questions when prompted. Participation is worth one point per day. Please REGISTER your clicker through Bb Learn before Friday, February 1. In order to register you will need the 6-digit Device ID located on the back of your clicker. For the first few days, at the beginning of each class I will have one quiz-type question on the large video screen at the top of the room. Answer that question when you arrive: this will let you know if your clicker has been set to the right channel and if your responses are being accepted. The Friday of the first week (Feb. 1) we will have a 10-minute tutorial, complete with a handout (please download it from webct), on how to use the clicker. Starting the following Monday (Feb. 4), students will accumulate points based on their participation with the clickers. Everyone will be expected to have purchased their clicker by Friday, Feb. 1. Exams: MIDTERM I Wednesday, February 20 MIDTERM II Friday, March 29 MIDTERM III Monday, April 29 FINAL EXAM Monday, May 20, 12:00 1:50 pm Please show up on time for each exam. You do not get extra time if you arrive late. Notes and textbooks are not permitted on exams. Students who need special accommodations for exams must have proper authorization from Accessibility Resource Center (ARC). Contact the ARC office at 898-5959 for more information. Practice exams will be posted on the Bb Learn site for you to download. The answers to those exams will also be posted in the days preceding each exam. There will be no opportunity for a make-up exam once the class has taken the exam. If you do miss an exam please contact Dr. Nichols immediately. Only basic non-programmable scientific calculators will be permitted for use on exams. Examples of acceptable calculators include the TI-30X and TI-36X. Graphing calculators like the TI-83+ and TI-89 are not permitted. If you have any questions please ask your instructor. Devices including smartphones and PDA s (iphones, Blackberries, and Droids) are also not permitted. Early exam-taking will only be permitted under rare circumstances. If you will be unable to take an exam as scheduled please contact Dr. Nichols as soon as possible. All reasons for early exam-taking must be verified in writing. Acceptable reasons include road trips for intercollegiate athletics. Unacceptable reasons include doctor s appointments and having multiple exams on the same day.

Attendance at the once-a-week labs is mandatory. Since the sections are very full, there will be little opportunity to make up a missed lab and no labs can be made up once the last section of the week (Friday) has completed the lab. If you must miss your lab, and you want to sit in on another section, you must get permission from both your normal lab instructor and the instructor of the section you wish to visit. Please don t make a habit of switching sections: you won t be allowed to do so more than twice. Answers to the pre-lab questions (listed in the table) are due right at the start of the lab period. Please hand the answers to the instructor before the lab period starts. Missing three (3) lab periods for any reason means automatic failure in CHEM 112. The policies for the due date of lab reports and acceptability of late work is set by the individual lab instructor. You must pass (with a D or better) BOTH the lecture part of the class and the lab portion of the class to pass overall. Lab scores will be calculated as such: o Labs: 14 @ 10 points each 140 pts o Pre-labs: 12 @ 3 points each 36 pts o Quiz 1 (week 10): 24 pts o Lab Exam (week 15): 50 pts o TOTAL 250 pts Lab grades will be standardized to approximately a B average to accommodate for different grading styles among the different lab instructors. - 3 -
Some Friendly Advice for Chemistry 112 Keep up! Falling behind early will lead to real trouble, particularly since the final exam is comprehensive. Attend all lectures. Even though no credit is directly given for attending lectures (attendance will not be taken), studies show that attendance directly affects performance. Read the textbook and keep up with the lectures. The topics under discussion each week are laid out in the calendar so there is no excuse for not being prepared for class. Do the assignments and do them on time. The assignments are worth only a few points, but more importantly they are practice for the exams, which are worth plenty of points. Copying homework answers from the study guide or from other people may get you the 2 points the homework assignment is worth, but since you wouldn t be taking the time to learn the material, your performance on the exams will suffer. Don t get lazy and fall into the TRAP of copying homework! Plan to invest 6-8 hours per week out of class to studying for Chem 112 in order to succeed. Successful studying involves ACTIVE learning: by doing problems, asking questions, and so on. People ask me how do I best prepare for exams? all the time. Two pieces of advice that I have: o Know the vocabulary. In each chapter, the important new vocabulary is summarized in sections called Summary and Key Words. Figure out the meanings of each word and the concepts to which they refer. o Do lots and lots of problems. There is no substitute for doing problems (numerical and nonnumerical) in learning new concepts. See above under Do the assignments. Turn your cell phones OFF during class hours. I have low tolerance for such things. If there is a circumstance (emergency) that requires you to leave your phone on please inform me at the beginning of the class. Be prepared to participate in class. Remember that someone will be invited to the board on occasion to do a problem. If you are confused about something in class, ASK! If you are still confused after class, ask again, in office hours, in lab, by e-mail, or however, until you are satisfied. Work together! Obviously on exams you are working on your own, but studies show that studying together and doing homework together are excellent ways for everyone to earn higher grades. You and the other students are not competing with each other: the grades in the class are not on a "curve". Be honest. Copying answers during exams and other forms of academic dishonesty are serious offenses and will not be tolerated. Instances of cheating will be reported to Student Judicial Affairs, and serious academic penalties are possible. Please refer to the catalog for further information. I will take several precautions to help prevent cheating, including: o Giving out different versions of exams and quizzes, which contain different questions. o Noting who sits next to whom in an exam setting and cross-checking answers. If you studied with someone do not sit next to them in the exam: it can lead to undue suspicion. o Checking ID of students during exams. - 4 -
