Instructor: Dr. Christina White Office: SM 251 E-­‐mail: [email protected] Phone: 949-­‐582-­‐4742 Office Hours: Mon. 11:00-­‐12:00, Tuesday 11:00-­‐12:00, Wednesday 11:00-­‐12:00 and 3:00-­‐5:00 Web page: http://www.saddleback.edu/faculty/cabel General Course Information • Welcome to Chemistry 1B. This course is intended primarily for chemistry, biology, and engineering majors, or others intending to pursue a bachelor’s degree in a science or science related field. • Topics this quarter will include equilibria, acid/bases, thermodynamics, electrochemistry, coordination chemistry, kinetics, qualitative analysis, and nuclear chemistry. Prerequisites • Chemistry 1B is a continuation of Chemistry 1A (you must have completed Chemistry 1A with a C or better). The material in this course is presented at a level that assumes that you are proficient in skills from Chem 1A. If you did not complete Chemistry 1A at Saddleback College, please see me about a possible mismatch of material covered by your first semester course taken elsewhere with that covered by Saddleback’s Chem 1A. • Mathematics through intermediate algebra (This is NOT an Algebra class. It is expected that you can do algebra and there will be little to no class time devoted to solving algebraic expressions. For example – it is expected that you know how to solve the quadratic equation. I will not be teaching you how to do this in class.) Course Materials: • TEXTBOOK: Chemistry, 9th Edition, written by Zumdahl with OWLv2 access code • LAB NOTEBOOK – a bound notebook (for example, a composition book) • A non-­‐programmable SCIENTIFIC CALCULATOR. (Acceptable models include, but are not restricted to TI-­‐30X series, Casio fx-­‐250HC-­‐s, or Sharp EL-­‐531LB) • A Saddleback email account – I’ll be sending important emails throughout the term. Supplemental Instruction (SI): This course will have a supplemental instructor associated with it. Trevor Clack, a former A student in this course, will attend the weekly lectures and will be available for 7 hours a week (times TBD and posted on the course web page) in the Learning Resource Center (LRC) to help you with homework, etc. Please take advantage of this unique opportunity and visit Trevor in the LRC! Note that other chem. tutors are also available in the LRC (times posted on the course web page). Course Organization: Class Time. Lab starts Monday and Wednesday at 8:00 AM sharp. Please make sure you are in class on time to prevent distracting classmates and the instructor by entering late. Also, you may miss important safety instructions if you arrive late. I reserve the right to ask you to leave if you arrive late to lab. Lecture starts at 12:00 sharp. Web based. Many of the course materials, such as full syllabus, lecture schedule, laboratory procedure and report forms, study guides, homework problems, worksheets, and additional materials are on-­‐line. Make sure to bookmark the class website and visit DAILY, because it is updated often. Attendance. Attendance in lab and lecture is essential for your success. Therefore, I expect you to attend every class meeting and be actively engaged during every class meeting. Prior knowledge. All concepts and skills from Chem 1A are considered prior knowledge you come into this course with, and some topics in Chem 1B will build on this prior knowledge. In particular, you are expected to have a good grasp of Thermochemistry (ΔH), nomenclature, stoichiometry, chemical reactions, and metric conversions. It is your responsibility to review these topics if you feel lacking in your knowledge base. Review assignments will be given (either through the online homework system or through worksheets) throughout the semester on material that you should have covered in Chem 1A that is important in Chem 1B. This will give you the opportunity to review this important material. Any difficulty with material from Chem 1A on these review assignments should be addressed by seeing me as soon as possible!

Exams. Four exams will be given on the dates specified on the class schedule. They are given in lab period and will start at the beginning of the lab period. The format of exam questions will include objective (matching, multiple choice, etc.), short answer, and calculations. Assignments. YOU CANNOT LEARN CHEMISTRY WITHOUT WORKING PROBLEMS • OWLv2: We will be using OWLv2, the online learning system that accompanies the 9th edition of our Zumdahl text this semester. This program works best on a PC or Mac but can be used on a tablet (may still have a few bugs with the tablet). Weekly homework assignments will include topics we covered that week in class that must be "mastered" in order for you to get full homework credit for the chapter. There will be 3 questions posed for each topic and you must get 2/3 correct in order to "pass". The questions are randomized and you can be given a new set of questions for the same topic up to 10 times. When the question is given, there will also be a direct link to the e-­‐book as well as tutorials and simulations to help you before you answer the question. You must get an 85% overall on the assignment in order to get credit for that assignment. See e-­‐
mail/webpage on how to enroll in OWLv2 for our course.  Assignments will be due on Sunday nights at 11:55PM. (I reserve the right to push back due dates; I will not move them up)  You will get no credit for assignments submitted past the due date. NO EXCEPTIONS. • In-­Class Problems: we will be working some problems together in class/lab. In-­‐class problems will be passed out during class time/lab time. You will be given full credit if you actively work on the worksheets during class, show your work, and turn the worksheet in at the end of class. You will not be given credit if you do not actively work on the worksheet during class, copy other students work, or just write the answer with no supporting work. There is much less time for working problems in Chem 1B than there was in Chem 1A (there is 2 less class hours per week!). So, it’s up to you to practice problems on your own! • Other Ungraded Problems: I will post suggested book problems and I will sometimes post additional worksheets on the web site. These are not collected. Solutions will be posted for worksheets I post. Odd numbered problems in the book have the answers in the book. It is strongly encouraged that you do these problems! • Any difficulties with the problems should be addressed by either seeing me in office hours or another outside source for help (i.e. someone at the LRC). We will not be able to work on all the assigned problems together. Therefore, you must utilize office hours if you have any questions. I strongly urge you to try ALL of the problems posted/assigned. The only proven way of learning chemistry is by repeatedly practicing and working related problems. A significant portion of the questions for exams will come from the problems or be very similar to the assigned problems. Final Exam. The final exam is comprehensive. The final exam must be taken at the scheduled time. There are no exceptions. Laboratory. The lab period will be used primarily to carry out experiments, but some lab time may be used for exams, for extra lecture discussion, or for working problems. Chemistry is an experimental science, no way around it. Thus, it is best investigated in a laboratory setting. That's not to say that lecture is not critical to learning chemistry, it is! But in a chemistry laboratory you learn important chemical principles by actively investigating them. Most people will agree that you typically learn concepts better by experiencing them in action, firsthand. Therefore, Chem 1B is not a complete course without a laboratory component. So, if you miss 5 or more labs during the semester, you will fail the course. If extreme circumstances arise that result in you missing a lab (i.e. family emergency, serious illness, etc.), you will need to notify me in advance (if possible) of the lab (in person, or by phone) and provide me with documentation to verify your reasoning (for example, a note from a physician) for missing the lab. Safety: Laboratory safety goggles will be issued to you and must be worn at all times that chemicals are used in the lab. You must wear closed-­‐toe and closed-­‐heel shoes to lab. Food and beverages are never permitted in the laboratory (even bottled water). I will ask you to leave if you are not following the safety rules and you will receive a 0 for that lab. Dr. White

Pre-­Lab Assignments: Some labs require you to answer pre-­‐lab questions. Pre-­‐labs will prepare you for the experiment and will provide valuable information for understanding the lab and answering questions on the pre-­‐lab sheet. Pre-­‐labs must be completed prior to lab arrival. I will check and stamp the pre-­‐labs at the beginning of each lab. You will lose 25% of your lab report score if it is not completed/attempted. The bottom line: get those pre-­‐labs done! You should attach the pre-­‐lab as the last page of your completed lab report. Lab Notebook: This notebook will be used to write the experimental procedures, to record data/observations, and to list sources of experimental error (you may also perform calculations in your notebook, but it is not required). I will collect the lab notebook throughout the semester.  To start your lab notebook, skip the first 2 pages for the table of contents. You will fill this in throughout the semester. Then, begin numbering the pages at the top right corner of the pages on the right only (the pages on the left will be used for notes and/or calculations).  Before each lab, you are expected to have read the experiment. You are also to prepare your lab notebook ahead of time. Preparation should include a DATE, TITLE, PURPOSE OF THE EXPERIMENT, an abbreviated PROCEDURE (don’t recopy the manual, shorten where you can; use an outline form, a flow chart, a picture representation, etc.), and DATA TABLES following those outlined in your manual.  I will spot check your notebook at the beginning of each lab period to check to see if you prepared sufficiently (if you are late, you will not get checked and lose points from your lab notebook score). Failure to prep sufficiently beforehand will result in a deduction for the notebook portion of your lab grade.  During lab, record data and observations directly into the lab notebook.  After the data are in your lab notebook, bring the notebook to me for a final check (I will stamp/sign it at the end of lab).  Use the following format for the lab notebook: 1

Use pen in your lab notebook. Do not use whiteout or scribble out mistakes. If a mistake is made, simply draw a line through any errors. Do not rip pages out of the lab notebook. All data and observations should be recorded directly into the lab notebook and then copied to your lab report form later. Failure to do this will result in a loss points from your lab notebook score. Before you leave lab, make sure that I have signed/stamped your notebook indicating that your data/observations have been recorded. *See Lab Notebook Sample handed out in class Lab Reports: Lab reports consist of completed data sheets filled out in pen. The following is required for all lab reports:  Always use complete sentences.  Always show each calculation in detail (include units and correct significant figures). Unless announced otherwise, lab reports must be handed in at the end of the lab period. There are no make-­‐
ups and two labs are dropped (excluding Exp.24/25: Qualitative Analysis of a General Unknown). Any report turned in one class period late or less will be downgraded by 25%. Any report turned in within one week will be downgraded by 50%. Any report turned in over one week late will receive a 0. Participation: You must be an active participant in the experiment each week, manipulating the chemicals, observing the reactions, and collecting data (i.e. don’t let your lab partners do all the work). If you miss a lab or your data is unusable, you cannot just “get the data” from a friend and turn in the lab. Also, It is allowed and expected that some students will work together on lab reports and other assignments. It is also expected that each student will do their own work and write their own answers in their own words. A good way to work together is to talk about a question, discuss an answer, and then each person writes an answer in his or her own words. An unacceptable way to work together is for one person to have an answer, and then for another person to write the same answer (i.e. copy directly). Lab Quizzes: There will be 5 in-­‐class lab quizzes based on the lab material (which directly relates to the material we learn in lecture!). Each will be about 30 minutes and will be given in the beginning of the lab period. Study guides will be posted so that you know what labs will be covered in each quiz. There will be no make-­‐up quizzes. The format of the quizzes will be similar to that of the exams. The dates for quizzes are listed on the course schedule. Grading. The final grade for the course will be determined by combining the scores (as a percentage) of the four exams, the final exam, the homework, and the laboratory portion of the course according to the weighted distribution shown below. COMPONENT PERCENTAGE Exams (4) 40% (10% each) Lab Quizzes 10% (2% each) OWLv2 Assignments/Review Assignments 7.5% In-­‐Class Problems 2.5% Lab Reports and Lab Notebook 20% Comprehensive Final Exam 20% 100% Grade Distribution. The following grade scale is guaranteed: > 90% for an A, 80-­‐89% for a B, 70-­‐79% for a C, 60-­‐69% for a D, >60% for an F. I will post grades as the quarter progresses in Blackboard, so verify your progress there and see me if the are any mistakes or questions. Other Business: Academic Dishonesty. Students who violate college standards of academic integrity are subject to disciplinary sanctions, including failure in the course. Since dishonesty in any form harms the individual, other students, and the Dr. White

college, policies on academic integrity are strictly enforced. Please review the department’s policy on academic integrity: http://www.saddleback.edu/mse/documents/integrity.pdf Special Services. Students requiring accommodations for a disability that may affect class performance are requested to schedule an appointment during the first week of the semester with a staff member in Special Services so that accommodations and an academic adjustment can be authorized. You are invited to set up a private appointment with me if you would like my help in getting started with this service or you may contact Special Services directly. Special Services is located in the Student Services Center, SSC 113, phone 582-­‐4885. The Special Services website is: http://www.saddleback.edu/dsps/ Withdrawals (Drops). If you want to drop the course, it is your responsibility to drop the course on MySite. I will not drop the course for you. If you stop coming to class and do not drop by the drop deadline, you will receive an F. The no penalty drop date is 2/1/2015 and the last day to drop is 4/13/2015. Class Expectations: As partners in learning, we should establish some mutual expectations of each other. My Responsibilities a course syllabus, clear lecture notes and examples a detailed subject study guide Your Responsibilities regular class attendance (in mind as well as body) currency in reading the textbook and doing the assignments timely completion of assignments visitations to office hours and e-­‐mail communications either for help or for confirmation of your work respect for me, your colleagues and yourself integrity quizzes and exams to guide & assess your learning office hours and e-­‐mail access to help you master the material respect for each person in the class a fair assessment of your mastery of concepts discussed Pointers to help you:  Read the book. Reading a chemistry book is not the same as reading a novel. Take notes while you read; work through calculations on your own; do the in-­‐chapter problems on paper as you encounter them in your reading. After you read a chapter, make an outline of the material that contains all of the important concepts, terms, and equations. Be an active reader, not a passive reader.  Do the worksheets and book problems (make sure you can do these problems by yourself WITHOUT looking at the answers). I’ll use a sports analogy again – you won’t be a very good basketball player if you just watch Kobe Bryant – you need to practice!  Keep up with the material, don't fall behind!  Come see me when you need help (don't wait and fall behind). I really enjoy helping students in office hours (it’s one of my favorite things about this job), so please see me to go over problems, lectures, labs, the book, or anything at all!  Study more than you think you need to. You are encouraged to cover the material three times: read the assigned material once before lecture, attend every lecture, and read the assigned material again before doing the homework.  Attend class and be an active participant. Do not show up, but sleep through lecture. Take notes; answer questions; ask questions.  Be prepared for lab and think about what you’re doing. If you are not prepared for lab, you will waste time and may not understand how to do the lab. Not only is this dangerous, but it will not help you understand the course material. Be an active thinker during lab. Don’t carry out the experiment without understanding why you perform each step. Dr. White
