II. MATERIALS:
Required:
Text: General Chemistry: The Essential Concepts, 5th edition, by R. Chang, McGraw-Hill Publishing, © 2008.
Lab notebook: Bundled with the textbook. Otherwise must be bound and have duplicate pages.
Lab manual: General Chemistry 106, Lab Manual, Spring 2008
Goggles: Indirect vented safety goggles (must bear the number Z87.1) are required for admission to the first lab period. State law requires that goggles be worn at tall times during the lab. They are available at the bookstore, and may be sold by the Chemistry Club. No goggles? No lab!
Calculator: Any make with scientific notation, powers, roots, and logs; does not have to be a graphing calculator. You may not use a graphing calculator if you take early exams.
Recommended:
Clicker: eInstruction response clickers will be used during lectures to award extra credit points (40 points maximum). The class code and a registration coupon will be
provided the first day of class.
Lecture manual: General Chemistry 106, Lecture Manual, Spring 2008
A. Attendance:
Regular attendance in all parts of the course is essential to achieve the course objectives.
An unexcused absence during a scheduled quiz or examination in any part of the course will result in a zero point score for that quiz or exam. There are no makeup quizzes or exams.
The reason for any excused absence from an exam, quiz, or laboratory session must be presented to your instructor (in advance if possible) and substantiated in writing with the student’s signature. Emailed excuses are not enough. Assignments and tests missed for a valid reason will not be counted against you, but you will be responsible for material covered in your absence. Advance notice of a pending absence will often make it possible to arrange for an alternate time for a quiz, exam or attendance in another lab section. If you miss more than one exam for any reason, you will receive an incomplete or a failing grade depending on the circumstances.
B. Grade Distribution: Points
Lecture Exams (5 X 200 pts.) ....................................................1000
Discussion Quiz (8 X 20 pts.)........................................ ........... … 160
Discussion Worksheets (10 x 20)............................................... 200
Laboratory ...................................................................... ................ 400
Total 1760
C. Grading Scale:
Your
final grade in the course will be determined by the total number of points you
have accumulated according to the following scale. This scale is only an approximation and the
instructor reserves the right to change the points required if necessary. Two unexcused absences from lab or unsuccessful
completion of the laboratory component (<50% of available points) will
result in a failing grade for this course regardless of how many points have
been accumulated.
Grade for total
points accumulated:
F: 0-879 (<50%) D: 880-1073
(50%) CD: 1074-1108
(61%) C: 1109-1249
(63%)
BC: 1250-1319
(71%) B: 1320-1495 (75%) AB: 1496-1530 (85%) A: 1531-1760 (87%)

D. Laboratory Grade:
Each laboratory meeting will be graded on a 20 point basis. The 20 points awarded for each laboratory meeting will be split between prelab, attendance, behavior, and record-keeping (your notebook). Your lab instructor has discretion over how many times your notebook will be checked during the semester, but count on this happening at least once. You will lose points for not showing up on time, not contributing to your team, not working safely, not wearing goggles, etc.
You will also be required to write lab reports and hand in data sheets. These are graded separately from and in addition to the above 20 points per lab.
Two unexcused
absences from lab or unsuccessful completion of the laboratory component (<50% of
available points) will result in a failing grade for this course. You may attend
another lab during the same week to make up a missed lab. Please contact the instructor ahead of time.
E. Discussion Grade:
Attendance at discussion is mandatory and you are expected to attend the section for which you are registered. Any long range schedule conflict must be resolved with the course coordinator.
Weekly problem assignments are to be completed before attendance at the discussion period. Any questions you may have should be asked before discussion; e-mail the instructor, stop in the instructor’s office, ask a tutor, ask another student, attend the workshop, etc.
A twenty (20) point quiz will be given during the first part of most discussion periods. It will have problems similar to those assigned for that week. Your best 8 quizzes, out of 9 possible, will be used to compute your Discussion quiz grade (160 points maximum possible). Unexcused missed quizzes will result in zeroes being entered into your quiz average.
The rest of the discussion time will usually be spent working in small groups on worksheets provided by the instructor. Each worksheet is worth 20 points, and you can accumulate up to 200 points for the worksheets. Material on the worksheets may not be covered in lecture, but will be on the exams.
If you know you are going to miss a discussion, please contact your instructor. You may be able to attend another discussion section to make up the work.
IV. COURSE POLICIES:
Misgraded quizzes or exams must be returned to your instructor for possible regrading no later than one week following their return. You should save all tests, quizzes, and lab reports so that you will have them available for review, and so that any chance of clerical error may be avoided.
It is YOUR responsibility to check D2L for the exam scores, quiz scores, lab scores and discussion points to determine that your scores were entered properly. Any error must be reported within a week of the posting date in order for it to be considered.
No radios, tape players, headsets or other recording or transmitting devices may be used during exams. Caps with bills must have bills turned to back of head. A student ID card is required when handing in exams.
Early exams will be offered for students who cannot attend the evening exams. Students who need to take an early exam must sign up with the instructor the week before the exam. Students taking an early exam will not be allowed to use a calculator with memory capability. You must either bring a simple calculator of your own, or use one provided by the chemistry department.
Lecture examinations will be computer scored and the answer sheet will not be returned to you, but retained by the lecturer for a permanent record. Answer keys will be posted on D2L and on the bulletin board outside HS‑403.
A WORD TO THE WISE: The most common reason for a poor grade in this course is the failure to keep up with the work on a daily or weekly basis. In general, if you attend all parts of the course, read the text, complete and understand the weekly problem assignments and lab experiments, you will pass the course (grade of C). If you study in addition to that, you should do better. If you experience difficulty with any part of the course, seek help immediately. If you let it slide, it becomes more difficult to catch up because the subject matter tends to be cumulative.
WORKSHOP:
A two-hour once-a-week workshop is offered on Mondays from
NOTE: The last date to drop this course without a Late Add/Drop Request Form is March 19. Students dropping the course must check out of lab before the drop is considered complete.
V. COURSE
OBJECTIVES
This course is intended to introduce the student to the language and the elementary theories of chemistry, to provide training and practice in analytical reasoning and problem solving, and to serve as the basis for further studies in chemistry. The lab portion is designed to provide training in the experimental techniques of chemistry, and to reinforce lecture material with concrete experience.
Specific areas in which the student is expected to achieve minimal competency by the end of the semester are the following:
INTERMOLECULAR FORCES-types of forces, relate to physical properties, phase diagrams
GAS LAWS- ideal gas laws, partial pressure, kinetic molecular theory, real gases
SOLUTIONS ‑ solution formation, concentration units, colligative properties, temperature and pressure effects
PRINCIPLES OF CHEMICAL REACTIVITY I -reaction rates, integrated rate laws and reaction orders, half-life, mechanisms, Arrhenius equation
PRINCIPLES OF CHEMICAL REACTIVITY II- equilibrium
systems, thermodynamic requirements, Keq, LeChatelier’s principle,
acid/base chemistry, pK versus acid/base strength, titrations, polyprotic
acid/base calculations, buffer, acidic/basic salts, Ksp related to
solubility, complex ion equilibria
ELECTROCHEMISTRY - electrolytic and galvanic cells, cell potentials, standard reduction potentials, thermodynamics and its relation to electrochemistry, equilibria and cell design, Nernst equation, batteries.
TRANSITION METALS - properties of transition metals and coordination compounds including color, magnetic properties, oxidation states, bonding theories
