Course Description: CHEM F105X-F106X, together, constitute the standard one-year

engineering and science-major general chemistry course with laboratory. 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. Co-

requisite: 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, Ka and Kb.

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.

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.
