Major subjects include reaction kinetics, equilibrium (including acids and bases, solubility and complex ion formation), atmospheric chemistry (time permitting), electrochemistry, and descriptive chemistry of the elements. Special fees apply. Prerequisites: A grade of C or better in CHEM F105X; placement in ENGL F111X or higher; placement in MATH F107X or higher; or permission of instructor and department chair. Corequisite: CHEM F106L. Students must be enrolled in both CHEM F106X and CHEM F106L to receive full credit. (3+3) Course Goal: As a result of the General Chemistry II (CHEM 106X) experience, students will have practiced using the scientific method, exercised basic laboratory skills, learned the basic theory of reaction kinetics and how it relates to equilibrium chemistry, worked with the principles and applications of electrochemistry, and learned the basics of energy. Student Learning Outcomes will be assessed through an American Chemical Society national standard chemistry exam given during the final exam period. Learning Outcomes: The intended learning outcomes for this course are to be able to apply the following chemical principles to solve problems in science and engineering: Identify the intermolecular and intramolecular forces existing between molecules of a pure substance and relate these to the observed differences in physical properties. Identify the effect of temperature and pressure on the physical states of matter with the use of phase diagrams and correlation to properties such as vapor pressure. Understand the basic types of structure and bonding of matter in the solid state.
Understand the solution process and correlation to thermodynamic properties based on intermolecular and intramolecular forces. Perform calculations and conversions based on different concentration units for solutions. Identify the factors affecting solubility of substrates in solution and calculations based on limits of a saturated system. Identify types of colligative properties of solutions and perform calculations based on boiling point elevation, freezing point depression and vapor pressure lowering. Develop expressions for rates of reactions based on tables of kinetics data. Correlate the effect of solution concentration and temperature on the rate of reactions. Postulate reaction mechanisms based on kinetic data and identify the effects of catalysis from a thermodynamic perspective. Understand the general concepts of solution equilibrium and the calculation of equilibrium constants. Use Le Chatelier s principle to qualitatively and quantitatively demonstrate the effect of perturbations to a solution in equilibrium. Relate the concept of equilibrium to solutions of weak acids and bases and calculations of ph, K a and K b. Understand the common ion effect and the relationship to buffer solutions. Calculate the ph of buffer solutions. Apply the concept of equilibrium to solution solubility and the precipitation and separation of ions for qualitative analysis of unknown solutions. Apply the equilibrium concept to spontaneous processes and correlation with thermodynamic quantities. Understand the concepts related to the operation of voltaic cells to determine spontaneity of redox reactions. Required Materials: You will need two things for General Chemistry II -- the textbook and an approved calculator. The on-line homework access (McGraw-Hill ConnectPlus) is optional. Textbook: Chemistry, 12th Ed, Chang and Goldsby, McGraw-Hill, 2013 (ISBN 9780078021510). Calculator: A non-programmable, non-graphing calculator will be required for quizzes and exams. Note: No instant response system will be required for this course, unlike other versions of 106X at UAF.
Course Structure: Most instruction will be in the lecture format. I do believe in active learning so I do call on students during lecture and expect students to participate in the learning process. Reading the book before lecture will be important for following and understanding the lectures. I plan to audio record the lectures and post them on the Blackboard System Web Page for this course. Generally, I do not post my lecture notes. We will cover almost all of the material in chapters 11 through 18 of your textbook and, time permitting, Chapter 20, Atmospheric Chemistry. I will note topics that you can omit as we go along. Homework: The best way to learn chemistry is by practicing! While there will be no graded homework as part of this course, suggested problems and questions at the end of each chapter in your textbook are representative of the material that I believe is most important for the students to understand. You should therefore strive to do as well as you can on these problems, being sure that you can complete any problem assigned as homework on your own. It is therefore strongly suggested that students should work these problems as a method of mastering the material. These are the types of questions and problems that will appear on the quizzes and examinations. Suggested problems and questions will be posted on the Blackboard System Web Page for each chapter. Quizzes: In lieu of graded homework, there will be six in-class quizzes during the semester. Quizzes will be given at the beginning of the class period and will last 10-15 minutes. You will be allowed to drop your lowest quiz grade. Exams: There will be four hour exams and a final during the semester. The dates of these exams are on the course schedule given later in the syllabus. Your lowest hour exam grade will be dropped. Hour exams will be given at the beginning of the class period and will last 60 minutes. Laboratory: Weekly lab exercises and small group learning activities will occur during the scheduled lab time. Attendance of labs is mandatory; failure to attend 4 or more labs will result in an F for the course! Final Exam: The final exam is scheduled for Thursday, Aug 9 from 9:00 to11:00 am. The final will be the American Chemical Society (ACS) standardized exam and is comprehensive. Failure to take the final will result in a grade of zero for the exam and your final course grade will reflect this fact. It is completely multiple choice and timed to be 120 minutes long. The topics listed under the learning outcomes listed above are all tested on the examination. Because the examination doesn t precisely match the topical coverage of our book, the raw score from the examination may be adjusted in the favor of the student for entry into the course grade calculation. A study guide is available from the ACS (Preparing for your ACS examination in general chemistry: The official guide, by Eubanks). It can be purchased online. Laboratory Grade: Laboratory grading and small group learning activities will be discussed during the first laboratory period. The purpose of the lab is to do hands-on investigation. We expect you to gain skills in scientific reasoning, experimental design, and use of chemicals and laboratory apparatus. The labs are conducted by graduate and upper division undergraduate teaching assistants. Lab reports will be handed in each week, to be graded and returned by the teaching assistant. Ten experiments are scheduled for the semester. The laboratory portion of your grade will be based upon the average of your best 9 lab grades. You can miss one lab with no impact on your lab grade. If you miss 2 or 3 labs, then 1 or 2 zeros, respectively, will be included in your average. Do not miss 4 labs: this results in a COURSE GRADE of F! Because lecture and laboratory are complementary and integrated, all students enrolled in Chem 106 (even those
who have taken the course before) must attend laboratory. Students must hand in 7 or more reports to earn a passing grade in this course. In other words, if you hand in only 6 (or fewer) lab reports, an F grade in the course is assigned, even if all your other grades are passing. This stiff requirement is based on the American Chemical Society stipulation that students must spend a certain number of hours in lab for courses such as Chem 106X (and of course you must attend lab in order to write a lab report!) There are no make-up labs scheduled during the semester. If you have special scheduling problems or if you miss more than one lab for an acceptable reason, please discuss alternative plans with Emily Reiter, Laboratory Director. Laboratory reports are due one week after a lab is completed. Late reports will be accepted, but the score will be reduced significantly. The last report of the semester cannot be accepted late. The first lab of the semester includes a safety review. Students must attend the safety review in order to continue in the course. Attendance: Attendance at lecture is strongly recommended and I expect that you are responsible enough to realize that. I will therefore not take attendance during lecture. If you can score well on the exams and quizzes without attending class, you are welcome to do so. However, by missing lectures you forfeit your opportunity to ask me questions. Attendance of the laboratory and all exams and quizzes is required. Due to the fact that the lowest exam and quiz grade are dropped, generally, there will be no make-up examinations or quizzes. In the event of illness or other catastrophic events, written evidence (doctor's note, etc.) must be supplied. The professor MUST be notified before the scheduled exam or quiz if a make-up is to be considered. Policy on cheating: Chemistry Department regulations require that any student caught cheating on graded work will be assigned a course grade of F. Course drop forms will not be signed in these cases. Policies on Exams: As stated earlier, there will be four hour exams and a final this semester. Exams will cover all material in the lectures and the suggested homework problems. Hour exam questions will include a variety of different types of questions such as multiple choice questions, fill-in-the-blank, mechanical plug-and-chug problems, and more difficult multi-step problems. The exams will emphasize understanding the chemical principles and applying them rather than memorizing equations, although there will be facts that you will be expected to memorize. Scratch paper, periodic table and constants/equations sheets will be provided with the exam. Exams will be closed book, closed notes.

The following final grade schedule will be used: A = 87-100% B = 76-86% C = 65 75% D = 54 64% F = <54% Electronic Devices: During in-semester and final exams, programmable and/or graphing calculators, cell phones, beepers, PDAs, and electronic translation devices are NOT allowed on your person. Power-off any such item, and place it inside your closed briefcase, purse, or pack at the back of the room, or on the floor. During lectures, all electronic devices, except calculators, are to be turned and kept off your desk. Support Services: Students with documented disabilities who may need reasonable academic accommodations should discuss these with me during the first week of class. You will need to provide documentation of your disability to Disability Services, 474-5655, TTY 474-1827.
