Chemistry 305 Summer 2017 Stephen Imai email: [email protected] office hours: by appointment Prerequisite Mathematics 100 (beginning Algebra) completed with a grade of “C” or better OR Math 103 and Math 104 with grades of "C" or better OR equivalent. Students who have not completed the math prerequisite will be dropped from the course. Proof of completion of the prerequisite must be submitted on the first class meeting. Class meets Lecture: MTWTh 11:00a - 1:05p L203 Lab: MW 1:15 – 4:25p L212 or TTh 1:15 – 4:35p L212 Required materials Texts: Lecture: Fundamentals of General, Organic, and Biological Chemistry, 8th ed., McMurray, et. al. Lab: Sacramento City College Chemistry 305 Laboratory Manual Approved laboratory safety goggles – available at the bookstore. Scientific calculator Mastering Chemistry access code – included with new text books or can be purchased separately from www.masteringchemistry.com Introduction Chemistry 305 is a one semester Introductory Chemistry course intended for students majoring in the allied health fields such as nursing, physical therapy, dental hygiene, etc. Chemistry 305 is designed to provide students to basic overview of chemical concepts and principles and laboratory skills for the purpose of establishing a foundation on which clinical and physiological applications are based. Chemistry 305 satisfies the GE lab science requirement for California transfer institutions. Study One of the keys to learning chemistry, as with any college subject, is to remain current by studying regularly and frequently. The amount of time you spend studying wil directly affect the grade you receive. If you want an "A" in the course, expect to spend a minimum of 2-3 hours a day studying chemistry. Some people find it advantageous to study with a partner or with a group. If you've never tried it, try it. Within a group, if there is something you don't understand you have someone you can ask. If someone else doesn't understand something, explaining it to them will deepen your understanding. Use all resources at your disposal. This includes, but is not limited to, your instructor. Please feel free to come to me with any questions. Exams, final There will be three exams, each worth a maximum of 200 points, during the semester and a 300-point final at the end of the semester. The exams and final will include material from lecture, the text, homework, and lab. The final is on the last day of lecture, Thursday, July 27, 11:00 am - 1:05 pm. All work must be shown to receive any credit on exams and the final. Missed exams cannot be made up. No early or late finals will be given. Quizzes Twelve 20-point quizzes will be given during the semester. You must show all work to receive any credit on quizzes. Quizzes will include, but will not be limited to, the most recent and current material. You will receive a score of zero on any missed quizzes and your ten highest quiz scores will count toward your grade. Missed quizzes cannot be made up. Homework Homework will be assigned for each chapter. Homework assignments will be online from Mastering Chemistry. Assignments are at www.masteringchemistry.com. Please check due dates carefully. At the end of the semester homework will be scaled to a maximum of 50 points possible. Late homework will not be accepted. Labs Lab will consist of experiments and workshops. A report is required following the completion of each lab and is due at the end of the lab period. You must complete and turn in all lab (experiment) reports to pass the class. Correct spelling and proper grammar are required. At the end of the semester your total score from lab will be scaled to a maximum of 120 points. Cheating If I am convinced that you have cheated on any assignment, exam, or final you will receive a score of zero for that assignment, exam, or final. If the offense is severe enough, you will be expelled from class. Nice people don't cheat. Please don't do it. Grading Your final grade will be based on the percentage of the total points possible that you have accumulated during the semester. The total points possible will be: Exams Final Quizzes Labs Homework Total 600 300 200 120 50 1270 Your grade will be based on the following scale: A > 90% > B > 80% > C > 70% > D > 60% > F Attendance Attendance is mandatory. You are responsible for all material and information presented in class and missed exams and quizzes cannot be made up. If you miss more than 2 class meetings without an acceptable excuse you may be dropped from the class. If you miss the first day of class you may be dropped. Course objectives Upon completion of this course, the student will be able to: -demonstrate a knowledge of introductory chemical concepts. -relate chemistry to applications in everyday life and the health sciences. -apply knowledge of quantitative chemical methods to chemical calculations, including application of the mole concept to stoichiometry and the use of dimensional analysis. -demonstrate the ability to perform basic chemical laboratory procedures using common laboratory equipment and to analyze the data collected. -develop chemical formulas from chemical names and vice versa for elements, ions, acids, ionic and molecular compounds. -formulate balanced chemical reaction equations and predict states of matter from solubility rules. -develop a general knowledge of the make-up of the atom and how it relates to periodic trends in chemical properties and chemical bonding. -differentiate between the characteristics of the three states of matter, the role of intermolecular forces in liquids and solids, and quantitative relationships of variables affecting behavior of gases. -identify the properties of acids and bases (and their conjugates) with the ability to convert back and forth between acid concentration and pH. -demonstrate a basic understanding of nuclear chemistry and its applications to medicine. -interpret simple organic chemical formulas and structures in relationship to VSEPR theory. General -All cell phones, computers, etc. must be turned off during class. This does not mean the ringer is turned to silent but that the device is turned off. -A web page to provide answer keys and other information will be available at: http://scc.losrios.edu/~imais/chem305 -Ask questions. This is very important to me. If you have a question during lecture raise your hand. If I don't see you, feel free to speak up. -Use my email for questions that come up outside of class. I tend to check my email frequently and it works pretty well for problem solving.
