2 Make-up Lectures, Assignments, and Exams: As a rule, there are NO make-up sessions, assignments, or evaluations. You must complete all labs or you will fail the course regardless of your total point accumulation. If you can anticipate an absence, please make arrangements well in advance with the instructor to potentially avoid such penalties. Missed exams and quizzes will receive a score of zero points. Also, the instructor reserves the right to have additional quizzes as necessary. Grading: There will be 3 exams, 12 labs, approximately 10 quizzes, and 1 final, which will comprise your final score in the class. Below is a rough outline of the points in this course. 3 Exams = 300pts (100pts each) Final = 200pts Quizzes = 100pts (10@ 10pts each) Lab = 120pts Total = 720pts <60%=F, 60-69%=D, 70-79%=C, 80-89%=B, %=A Homework: Homework assignments are posted on the website and are optional. However, the homework will cover related material to the lectures and are an excellent way to prepare for taking the exams. It is in your best interest to do the homework fully, and with great fervor, as it will directly aid you in succeeding in this course. Electronic Devices: Be sure all cell phones and pagers are turned OFF before lecture and/or lab begins. Electronic means of recording the lectures are not permitted (this includes both audio and video recording). Additionally, laptop computers should be stored during lectures; take notes the old-fashioned way (with paper and pen). Cell phones are NOT to be used as calculators during exams. Additionally, ipods, and the like, are also banned from lectures and labs. Laboratory Requirements: You are expected to be prepared for lab BEFORE starting the experiment. This includes attending the lab lecture at the beginning of the week and familiarizing yourself with the requirements of the lab days before doing it. It is unwise to assume that you might be able to walk into lab unprepared and be able to finish the lab. Be Prepared! Proper lab safety attire will be strictly enforced. This includes: having shoes that fully and completely cover your foot, safety goggles that fully seal around your face (glasses are inappropriate), long hair must be tied back and in a bun, and clothing that covers from shoulders to knees. Failure to have this proper attire will result in ejection from lab and the inability to do the lab. All labs must be performed in order to complete the class. Failure to do so will result in a failing grade for the course. The lab is integral to the course, and it part of the requirements for credit. All lab reports will be turned in one week after the lab is completed. Failure to turn in a lab report, regardless of whether or not you did the lab, will count as an incomplete assignment, and will disallow you to complete the course. Late labs will not be accepted.

3 Letters of Accommodation: Approximately half of all college students have some special learning need. The College s Disabled Students Programs and Services (Room 1339E) offers services to identify students that may require accommodations in coursework or examination situations. The College and its instructors are legally required to make the arrangements explicitly stated in the student s Letter of Accommodation. If you have such a letter, please arrange for a meeting with me immediately. Tutoring: Napa Valley College offers a tremendous number of services designed to help students succeed. It is in your best interest to seek them out BEFORE you need them to pass the course. Obligatory Statement of Academic Fraud : All work must be of your own original composition. Plagiarism from any source (books, papers, fellow classmates, Internet, etc.) or unethical behavior during exams (unauthorized crib notes, a neighboring exam, communication (verbal, written, electronic, or otherwise), etc.) will not be tolerated. The fabrication or use of data other than your own in the laboratory reports is considered fraud. A failing grade will be assigned for the course and drop forms will not be permitted. In addition, the matter will be turned over to the College and your home department for further judiciary and disciplinary actions. Consult your student handbook for additional information on this and other Honor Code stipulations. Consider this statement as your first, last, and only warning regarding this matter. Instructor: The best way to get in touch with the instructor is by (fquinlan@napavalley.edu). Because the office is shared, is the only way that is guaranteed to get your message delivered. The office is located in room 1843.

4 STUDENT LEARNING OUTCOMES: Communicate chemical and physical processes at the molecular level and how they relate to the macroscopic environment. Solve both qualitative and quantitative chemistry problems while demonstrating the reasoning clearly and completely. Implement laboratory techniques correctly using appropriate safety procedures and express them clearly in written laboratory reports. COURSE OBJECTIVES: Explain the development of chemical principles and concepts based on experiments. Analyze and solve complex or extended problems involving mathematical skills as well as an ability to place these problems in an environment, biological, economic or social context. Design a laboratory experiment by defining the problem, collecting data, obtaining results, deriving conclusions, and preparing a report to communicate the information to others in writing. Explain the concepts related to rates of reaction, activation energies, mechanisms of reactions, as applied to the kinetic molecular theory. Relate equilibrium information from chemical systems to the free energy, enthalpy and entropy. Determine the equilibrium constants and show how the spontaneity of the system is related to the driving force of the reaction. Apply the equilibrium system concepts to acid/base, solubility, redox, and complex ion formation reaction systems. Indicate how an electrochemical cell can be used to establish the standard free energy of a chemical reaction, and measure the ph of a system.

5 LABORATORY SAFETY RULES Your participation in this laboratory requires that you follow safe laboratory practices. You are required to adhere to the safety guidelines listed below, as well as any other safety procedures given by your instructor(s) in charge of the course. You will be asked to sign this form certifying that you were informed of the safety guidelines and emergency procedures for this laboratory. Violations of these rules are grounds for expulsion from the laboratory. Note: You have the right to ask questions regarding your safety in this laboratory, either directly or anonymously, without fear of reprisal. Goggles must be worn at all times while in lab. You must purchase a pair of goggle for yourself and you may store them in your locker. You will be advised of the appropriate goggles to be purchased. Locate the emergency evacuation plan posted by the door. Know your exit routes! Locate emergency shower, eyewash station, fire extinguisher, fire alarm, and fire blanket. Dispose of all broken glassware in the proper receptacle. Never put broken glass in the trashcan. Notify you instructor immediately if you are injured in the laboratory; no matter how slight. Never pipette fluids by mouth. Check odors cautiously (i.e. wafting). Never taste a chemical. Shoes must be worn in the laboratory. These shoes must fully enclose your foot. Long hair must be tied up in a bun during lab work. Loose long sleeves should be avoided in the lab. Children and pets are not allowed in the laboratory. Eating or drinking in the lab is prohibited. Do not drink from the laboratory taps. Wash your hands before and after working in the lab. Turn off the Bunsen burner when you are not using it. If any reagents are spilled, notify your instructor at once. Follow the instructor s directions for disposal of chemicals. Only perform the assigned experiment. No unauthorized experiments are allowed. Every chemical in a laboratory must be properly labeled. If a label is unclear, notify your instructor. Use the proper instrument (eye-dropper, scoopula, etc.) to remove reagents from bottles. Never return unused chemicals to the original container. Do not cross contaminate reagents by using the same instrument for 2 different reagents. (e.g. don t use the mustard knife in the mayonnaise jar) Material Safety Data Sheets (MSDS) are available for your reference. These contain all known health hazards of the chemicals used in this course. In addition, there is information concerning protocols for accidental exposure to the chemical. You are advised to inspect this binder.
