1 Shasta College Division of Science, Language Arts and Math GENERAL CHEMISTRY (Chem 1A) First Day Hand Out Spring 2011 CHEM 1A, Number of Units, 5 Course Instructor: Dr. Divan Fard, PhD, Office: 1406, Phone , dfard@shastacollege.edu Office Hours: Monday 1:00-3:30 PM Wednesday 1:00-3:30 PM 1. Course Description and Philosophy: Chemistry plays a pervasive role in all our lives. Hundreds of materials that you and your family use directly and indirectly every day are products of chemical research. The development of pharmaceuticals, plastics, (nylon, polyethylene, Formica, Seran, Teflon, Hollofil, Gore-Tex, Polyester, silicone, etc.), fertilizers, computer chips, paper and wood products are results of chemical studies. Most fields of study require one year of college chemistry. In America every year over 400,000 students register for this course of which only 10,000 are chemistry majors. Upon successful completion of this course, students will be able to: A) Demonstrate an understanding of atomic structure, the way atoms combine to form a molecule, stoichiometry of a chemical reaction, heat transfer in a chemical reaction, states of matter under different conditions, interactions between molecules and shapes of different molecules. B) Apply the above principles in solving problems C) Conduct laboratory experiments, which will enable students to develop skills necessary for experiments in an inorganic lab and to develop an appreciation for the basic principles of chemistry. 2. Prerequisite: High School Senior Chemistry or chem 2A, and two years of high school algebra. 3. CourseTime and Locations Please see your enrolment sheet for this information. 4.

This book is on reference for your use in Science Learning Center, in 1600 building. The study guide for this book is also available as reference in Science Learning Center. Test Item File, ISBN-13: is providing questions similar to exam, this book is a good tool to self-evaluation tool and prepares you for the tests. This is available as reference in Science Learning Center 5. Suggested learning guidelines: Chemistry 1A students will attend lectures, participate in discussion and run experiments in the laboratory. The class meets five times a week for a total of 7 hours (lecture (3 hrs), discussion (1 hr.) and lab(3 hr)). The instructor will use PowerPoint slides, transparencies, white board, computer animations and videos as educational aids. Students will be asked to do end of chapter problems as homework. The Study Guide by, Joseph Topich, (Solution Manual to McMuarry, J., Fay, R.C), can be of real benefit to the student. For each chapter in the text, the study guide provides. * Detailed solutions to all in-chapter problems; * Understanding key concept * A detailed solution to all ends of chapter problems If interested, students can purchase their own copy of the Study Guide from the bookstore or order them on line. The laboratory meets once a week (3 hrs). Students are required to study the theoretical considerations of every experiment and understand the objectives of the experiments. Student carrying out experiments in a lab are considered workers, and the lab will be their workplace. Therefore, they need to identify dangerous chemicals in the lab and be able to protect themselves. The required information is provided in what is called Material Safety Data Sheets (MSDS). Students are requested to consult with the MSDS before 2

3 running an experiment. Materials Safety Data Sheets (MSDS) of all chemicals used can be found in room 1411, please ask the science technician to see the MSDS forms. For every experiment there is one or more data and several questions sections. Data are to be filled out or recorded as you are doing the experiments and questions must be completed neatly and handed in at the end of; the laboratory period. The Chemistry Laboratory is a potentially dangerous place if students fail to observe safety precautions. Every student must acquire and wear a pair of safety goggles. These must be ANSI approved safety goggles. You can purchase these from Science Learning Center through Science Club students. Contact lenses are not a substitute for safety glasses and are particularly dangerous if a chemical gets in the eye.. In order to eliminate accidents in our laboratory as much as possible you are required to read and obey the simple rules of safety outlined handed in to you at the beginning of the semester. Synchronizing lectures with labs has always been a problem in chemistry courses and sometimes lectures and labs may not correlate exactly with one another. This is because it is often not possible to keep up the pace to topic changes in the lab. There will be a brief (approx. 10 min) canned lecture on experiments, which explains the theoretical and experimental aspects which are not covered in the lectures, or may need to be reviewed. Exam Preparations: 1) Read Your Book and lecture notes thoroughly and solve assigned problems. 2) Use Companion Web site below to test your understanding, and get answers to your questions: 3) Use Practice Tests to see exam sample questions: Available on instructor s web site: 6. Attendance Policy: Students are expected to attend all lectures. If more than four hours of lecture are missed, the student will be dropped from the course by the instructor. Students must attend every laboratory. Students who miss a lab, without previous arrangement for a make up lab, will receive a zero mark for that lab. IT IS ALWAYS THE STUDENT'S RESPONSIBILITY TO OFFICIALLY DROP OR WITHDRAW from the class. Students who fail to file the necessary forms, even though they stop attending class, will be assigned a course grade Missing an Exam or Quiz 3

4 There would be no make up exam or quiz. Students, who miss an exam or a quize, they could only replace their missing mark with the final exam mark. 7. Evaluation procedures: The following components make up the mark for this course: Discussion assignments 10% First test 13% Second test 13% Third test 13% Final Exam 31% Laboratory 20% 8. Grading system: % A % B % C % D 59-lower F Student s Right of Confidentiality and Privacy Students have the right to confidentiality and privacy and they are encouraged to use their student ID number on all exams and assignments. However If they are comfortable with their score to be seen by teaching assistant(s), they could write their name instead of their student ID number. 9. Accommodation of Disability If you feel that you will need academic accommodations in this class due to limits imposed by a disability then contact the Disability Resource Center ( ) to make the necessary arrangements. It is the student s responsibility to provide documentation that verifies the disability and the type of limitations that may result. The Disability Resource Center has been delegated the authority to, 1) evaluate that documentation and determine if it is sufficient to justify accommodations, 2) determine which accommodations are appropriate, 3) facilitate the provision of approved accommodations. 10 Lecture Topics: 4

Lab reports: Laboratory Report and Note Book All students are required to have a hardbound laboratory notebook to record all measurements, observations, physical changes and all other data. All suggestions for improvements during the experiment must also be written in laboratory notebook. The Laboratory book must have index of all experiments and page number of each experiment. Therefore, leave the first two pages of the lab oratory book blank for index of experiments. A typed lab report should be handed in a week after completion of each experiment. General Plan for Laboratory Report Number and Title of Experiment Chemical Equations: If applicable Procedure: Be sure to write a brief procedure. This does not mean copy the procedure from the lab manual.. It should be a summary of what you did, and not necessarily exactly how the lab manual wrote it. The instructor may modify some labs. This could be due to lack of time, mistakes, etc., and these modifications should be noted in the procedure. The procedure should be written in third person past tense. For example, instead of saying We dissolved 0.30 grams of impure Benzoic acid in 10 ml of water you should say 0.30 grams of impure Benzoic acid was dissolved in 10 ml of water. Try not to say we or I. Observations: 6

7 Write down physical observations in this part. Observations include color, phase, smell, texture, shape, size, behavior, and numerous other characteristics that can be seen during a reaction. Always note the appearance of starting material and product as well Calculations: In this section you show all calculation involved in determining the results of your experiments. Results: These must be tabulated measurements, calculated concentrations, other data collected during the experiment. Results must be clearly and systematically presented. Discussion: This section should be very brief and should include conclusions and the student discusses what can be done in future experiments to prevent such errors and improve results. Questions: Answer all question related to the experiments, this include questions posed to you in the procedure or on the last page. 13.
