3 CHM 111 Syllabus - Spring /9 Course description: This course is a continuation of the introductory college chemistry sequence. Topics included are states of matter, equilibrium, kinetics, and thermodynamics. Course meeting times: Time Room Lecture 9:30 PM - 10:45 PM, TTH 5404 Lab: Section 1 2:30 PM - 5:20 PM, T 5402 Evaluation and grading: Your course grade will be determined by the following: Tests and final exam **** 75% Laboratory 25% **** The cumulative final exam at the end of the course counts as two test grades. For the first CHM 111 test only, there will be two versions given. Students will take the first version of the test and then take the second version of the test the following week (as shown under Important Dates later in this syllabus). The higher grade of the two versions will be recorded in the grade book. Grading for the laboratory section of the course is described later in this syllabus. The grading scale for this course is a traditional ten-point scale. Letter grade Grade range A 90+ B C D ** F Below 60 ** You must earn at least a C to receive transfer credit at most area colleges!

If you are absent or fail to participate in more than 10% of the total hours that a course usually meets during a semester, you will be subject to a failing grade or withdrawal by the instructor. It is your responsibility to initiate a withdrawal if you are unable to complete course requirements. Exceptions to this policy can be made only by the appropriate Associate Vice President. If you must be absent from the class for any reason, you are responsible for any missed notes or assignments. Remember that each day's notes will be posted on the course web site. You will not be allowed to make up labs. One laboratory report grade will be dropped at the end of the term. If you miss one laboratory session for any reason, that report grade will be dropped. If you attend every lab, your lowest report grade will be dropped. You will receive a zero grade for the second missed lab, and will be withdrawn from the course (after the withdrawal deadline, withdrawal is counted in your GPA as a failing grade) after a third lab absence. You are still responsible for knowing the details of any experiment you miss on your lab exam. There are no make-up tests. If you miss a single test, the final exam grade will count in place of the missed test. If you know in advance that you will be absent on test day, you

5 CHM 111 Syllabus - Spring /9 may contact me at least 3 days prior to the test date and I may (my option) allow you to take an early exam in the testing center. You will receive a zero grade for the second and any further missed tests. In short, it's vitally important that you be in class and lab. In a college-level chemistry course, you can't afford to fall behind. Withdrawal policy: Students who do not complete course requirements must withdraw prior to the withdrawal deadline, or they will receive an "F" in the course. The last day to withdraw from CHM 111 with a "W" is March 18, After this date, you may withdraw from the class only with the permission of the appropriate FDTC associate vice president. If you simply stop coming to class before the withdrawal date, you will be assigned a "WF" (withdrawal - failing) grade. If you stop coming to class after the withdrawal date, you will be assigned either an "F" or a "WF". "WF" grades will affect your GPA here at Tech. Disability statement: If you have a documented disability and require special assistance or accommodations to participate fully as a student, or if you need more information, please contact Maureen Shuler, Room 104, Academic dishonesty policy: All forms of academic dishonesty including, but not limited to, cheating on tests, plagiarism, collusion, and falsification of information will be subject to disciplinary action. Cheating is defined to include, but not limited to, the following: Copying another student's work or test. Using unauthorized materials during a test. Collaborating with another during a test or on non-collaborative assignments. Knowingly obtaining, using, buying, selling, transporting, or soliciting in whole or in part contents of a test or other work. Bribing another person to obtain tests or information about tests. Substituting for another student, or permitting another to substitute for oneself. Plagiarism is defined as the appropriation of any other person's work and the unacknowledged incorporation of that work in one's own work offered for credit. Falsification of information is defined to include, but not limited to the following: Forgery, alteration, or misuse of college documents, records, or identification. Destruction of evidence with the intent to deny its presentation to the appropriate hearing or panel. Any proven case of academic dishonesty will result in an "F" for the assigned work or

6 CHM 111 Syllabus - Spring /9 test and may result in administrative withdrawal from the course, with a grade of "F" assigned after an administrative hearing. Additional sanctions, including administrative probation or suspension, appropriate to the incidents may be imposed pursuant to the Student Code and Grievance Procedures. Cell phones / electronic communications devices: Cell phones and other electronic communications devices must be switched off before class or laboratory starts. If your cell phone or other device rings or vibrates loudly enough to disrupt the class, you will be asked to leave the classroom for the remainder of class. If you are employed in a job where you are required to be "on call" during class hours (police, fire, EMT, etc.), please provide me with appropriate documentation at the beginning of the semester. If you have an emergency situation that requires your cell phone to be on during class, please let me know before class. Since cell phones and similar devices can be used to transmit test answers to and from the classroom, any use of cell phones or similar devices during a test will be considered cheating and will be dealt with accordingly.

The first, second, and third laws, free energy (definition, spontaneity, and interpretation), free energy and equilibrium LABORATORY INFORMATION Lab schedule: Labs meet once a week. The laboratory schedule for this course is posted on the course web site. You should visit the course web site and print out a copy of the laboratory schedule, or enter the experiments into your personal calendar. Lab grading: The lab grade will be tallied at the end of the semester and counted as part of your course grade. Labs are cooperative exercises. You will work in teams for each experiment, and your grade will be partially determined by your team's performance. You will turn in a laboratory notebook at the end of the laboratory term for assessment. Your laboratory average will be calculated by adding together all of your laboratory report grades, adding in the two notebook evaluation grades, and then dividing by the total number of grades. This laboratory average will count for 25% of your overall course grade. If you miss a lab, you will not get credit for that day's work (since you weren't there). The rest of your team will not be penalized. Most of the laboratory reports you will prepare in CHM 111 consist of completing report forms and questions found in the laboratory manual. You may tear out these pages of the lab manual to be turned in, or you may submit your reports on photocopies of these pages. (You will not be allowed to turn in your results and answers to questions on notebook paper.) Laboratory reports are due at the end of the laboratory period, unless another date is assigned by your instructor. Late laboratory reports (and late notebooks) will be penalized ten points per day (including weekends) late. Your laboratory notebook will be evaluated twice during the semester - once near midterm, and once after the last experiment. The notebook will be checked for proper format and proper content. Guidelines for notebooks are posted on the course web site. If you are not sure whether you are doing your laboratory notebook correctly, ask your instructor to review it during a laboratory period. Lab teams: You will be assigned a team at the beginning of the semester. Lab teams will consist of either two (minimum) or three (maximum) people. You will work with your team the entire semester if possible. If for some reason you would like to change teams, please come see me. If a team drops to one student, teams will be rearranged so that everyone has a team of at least two people again. (This might require breaking up of a threemember team.)

9 CHM 111 Syllabus - Spring /9 Use your team members as a study group! Lab policies: You are responsible for working in the lab in a safe manner and for leaving the lab and the lab equipment clean and in order. Here are some things you need to be aware of while in the lab. Safety. (This is a brief summary - we'll go over more in lab) 1. Safety is your top concern in the laboratory! 2. Some of our chemicals can hurt you in small amounts. Handle all chemicals carefully. 3. Be aware of safety features of the lab such as eye wash stations and fire blankets. 4. Wear safety goggles and protective aprons when anyone is working in the lab. 5. Do not eat or drink in the lab. Cleanliness: (This is a brief summary - we'll go over more in lab) 1. Clean glassware after use. Don't put dirty glassware back in the drawers. 2. Return glassware to the place you got it after you're done. 3. Clean up any spilled chemicals. In particular, check on or around balances. 4. Throw trash in the wastebaskets, not in the sinks. Trash in the sinks clogs our drains. Preparation 1. Students are expected to read the assigned experiment(s) before each lab session. 2. Students will not be allowed to perform an experiment without a lab manual and lab notebook. 3. Each student must bring a scientific calculator to each session. Chemistry is a quantitative science, and almost all of the experiments require calculation. 4. Any student arriving to lab more than twenty minutes after the lab's scheduled start time will be counted absent and will not be allowed to participate in the experiment.
