Required Textbooks and Materials
J.E. Brady and F. Senese, "Chemistry: Matter & Its Changes," 4th ed., John Wiley & Sons, Inc., New York, NY, 2004.

R.R. Reeder, C.D. Schaeffer, Jr., and J.L. Hedrick, "A Manual for General Chemistry Laboratory," 5th ed., Elizabethtown College, 2008.

C.D. Schaeffer, "Qualitative Analysis," Elizabethtown College (distributed in laboratory).

Laboratory notebook, 60 leaves, quad. ruled. This bound notebook is for your laboratory work only.

Safety goggles for use in laboratory. Prescription eyeglasses are no longer sufficient alone for laboratory use.  Contact lenses and sunglasses also do not meet the requirement and may not be worn.

An additional notebook of your own choice for lecture notes.

An electronic hand calculator capable of addition, subtraction, multiplication, division, squaring, square root extraction, logarithms, and antilogarithms.  Calculators may not be shared during examinations or quizzes.

At least one pair of light-weight gloves (such as those commonly available at many grocery stores) is strongly recommended for use in the laboratory.

Supplemental Work
Optional reading is listed at the end of every textbook chapter. More homework problems may be found in any other general chemistry book, many of which may be found in the chemistry library, room 104, Musser Hall.

Objectives
Ch 105 is a one-semester, in-depth survey of chemistry for those who plan further study in chemistry. It introduces current concepts and principles by which chemical behavior may be understood, as well as techniques for the application of chemical knowledge to a variety of problems. Topics include:

Acid & Bases
Atomic & Molecular Structure
Atoms & Elements
Bonding
Colligative Properties
Compounds & Reactions
Equilibrium & pH
Intermolecular Forces
Measurements
Reactivity
Solutions & Solubility
States of Matter
Stoichiometry

In addition to the information content of each topic, it is important that each student develops the ability to use that information effectively. Students will be expected to:

1. Correctly define and use terminology and nomenclature related to the topics.

2. Apply theoretical concepts to specific examples to yield qualitative analyses and predictions of behavior.

3. Perform quantitative calculations related to the topics to obtain numerically correct results with proper units.

4. Apply principles to specific examples in order to identify substances, describe processes, formulate solutions to problems, and interpret information and data.

5. Perform laboratory procedures, make accurate measurements, and interpret experimental data.
 

Attendance
Regular prompt attendance at lectures and laboratory is required. Students will be responsible on examinations for information presented in the lectures, as well as for reading, problem assignments, and laboratory experiments up to the date of the examination. Prompt and full attendance at every laboratory session is also required. Each experiment must be conducted during the week it is scheduled. Students are required to complete each experiment; failure to do so will result in a course grade of F.

Problem and Reading Assignments
Responding to questions and problems in frequent and serious study sessions is the most effective learning technique. Answers for many of the problems are found near the end of the textbook. Examinations may deal with questions of a similar nature to those in the homework. If you delay problem solving and studying until just prior to the examinations, you will do poorly.  Studying is not cramming.

Examinations and Quizzes
Three examinations will be given during lecture periods on the indicated dates.  Under no circumstances will these examinations be rescheduled. Brief quizzes will be given during lecture periods. The dates and topics of the quizzes may or may not be announced in advance. A comprehensive final examination will be administered at the end of the course during the final examination period. Attendance at exams and quizzes is required; there will be no make-up exams or quizzes under any circumstances. An unexcused absence from an exam or quiz will be rewarded with a grade of zero.

Laboratory
Preparation to conduct laboratory work begins with a careful reading of the appropriate project prior to coming to laboratory, room 108 in Musser Hall. Based on that reading, plan your work and outline that plan in your laboratory notebook before coming to your laboratory section. Each laboratory has a faculty instructor and one or more advanced student assistants. When you arrive at the laboratory, one of these people will check your notebook to determine your understanding of the work to be done. He or she will also check to see that you have completed the previous week's work and that you have submitted your results. If, in the instructor's opinion, you are unprepared, you will not be permitted to work at that time. If you are behind in laboratory work, you will be told to complete the outstanding work before beginning a new experiment. If you are both prepared and current, you will be signed in and you may conduct your work. The projects must be completed before the end of the period during which they are scheduled.  Reports submitted at other times may not be accepted, making you liable to repeat that experiment. Before leaving the laboratory, you must complete the analysis called for at the end of the experiment, and report the results to the instructor.  On several occasions noted in the laboratory schedule, you will conduct an experiment in the normal fashion and, during the following week, reflect on your work and method. After planning ways to improve your results, you will conduct the same experiment during the following week and, based on your notebook records, submit a written report on your work. These reports will be graded by the instructor and will contribute to your final course grade. Documentation standards and additional guidance in the preparation of these reports will be provided in class and laboratory. Reports submitted late will be penalized and may not be accepted. The laboratory is a very important part of this course. Attendance is required at all sessions.  The penalty for any incomplete laboratory work remaining after 2:00 p.m. on Friday, December 5, 2008, is failure of the course.

Grading
A grade is not an entitlement.  Examinations and quizzes will be graded on a scale of 0-100%. Letter grades corresponding to these percentages are as follows:

0 - 59% = F
60 - 69% = D
70 - 79% = C
80 - 89% = B
90 -100% = A

Final grades will be determined by combining examination grades (50%), the final examination grade (25%), a composite of quiz grades (12.5%), and a laboratory evaluation (12.5% for performance, attendance and reports). Letter equivalents to the final numerical total are as follows:
 
0 - 59% = F 70 - 72% = C- 83 - 86% = B
60 - 62% = D- 73 - 76% = C 87 - 89% = B+
63 - 66% = D 77 - 79% = C+ 90 - 92% = A-
67 - 69% = D+ 80 - 82% = B- 93 -100% = A

Students may request a grade of "I" by submitting a formal written request to the professor of the course.  Grades of "I" are assigned for extenuating circumstances only.  They are not given simply to allow additional time to complete required course work or to improve a course grade.  Forms are available in the Registration & Records Office.

Academic Integrity
Students are expected to be familiar with the policy regarding academic dishonesty and plagiarism as outlined in the College'sStudent Handbook, and in the most recent edition of the pamphlet, "Academic Integrity at Elizabethtown College." These activities will not be tolerated, and will be penalized severely.

Disability Statement
If you have a documented disability and need reasonable accommodations to fully participate in course activities or meet course requirements, you must:  (1) contact the Director of Disability Services, Tammie Longsderff, in the Center of Student Success, BSC 226, 717-361-1549, longsdtl@etown.edu;  and (2) meet with me, the course instructor, with two weeks of receiving a copy of the accommodation letter from Disability Services to discuss your accommodation needs and their implementation.

For the Record
Illness and Family Emergency.  Since absence will negatively impact learning, contact the instructor promptly in the event that work or related obligations are unattended.  Make sure that you obtain notes from classmates on all missed material.  The decision as to the nature of any makeup work is entirely at the discretion of the instructor.

Laboratory Awareness


1. Protective eyewear is required.  If glasses are worn, they must have attached side shields.  Contact lenses are discouraged and in themselves do not fulfill the requirement.

2. Wear suitable attire (e.g., no shorts or skirts, only closed shoes but no sandals, nonflammable clothing, etc.).  Wearing of a lab coat or apron is recommended.  Tie back or secure long hair.

3. Know the location and operation of all laboratory safety equipment.  Use the fume hoods as much as necessary to minimize the presence of undesirable vapors.  Keep your face out of the hood and keep the  hood window down as much as possible.  If the need to use a safety shower or eyewash station arises, insure sufficient washing or irrigation time and volume to mitigate the problem.  Irrigate the contaminated eye until the problem is corrected, making sure that the eyelid is pulled back to expose the eye.  If a chemical is spilled on you, wash the area immediately with water.

4.  Be familiar with the chemical properties, physical properties, and toxicity of the substances with which you will be working.  Ask your instructor to direct you to the location in the chemistry library containing this information.

5.  Wear gloves if reagents are toxic, corrosive, or if there is any doubt.

6.   Create & maintain a clean and orderly workspace appropriate for the environment and compatible with the experiment in progress.  Anticipate the consequences of your actions and plan all work accordingly.  It is also your responsibility to insure that your laboratory neighbors act in like fashion.  Everyone assists with cleanup at the conclusion of work.

7.  Exercise caution when transferring reagents in order to minimize the potential for spills and for contamination of the bulk supply.  The incorrect manipulation of container lids is also a common source of contamination.

8.  Place waste chemicals in appropriate containers labeled with the contents.  Consult an instructor for further details on proper disposal techniques.  Place discarded glass only in the special containers designated as such.

9.  Use an open flame in this course only when directed to do so.

10.  Transport liquids or solids only in closed containers.

11. Always be on the lookout for pressure build-up.  Never heat a closed system.   When extracting with a separatory funnel, always vent the pressure before and  after shaking.  It is prudent to begin an extraction in a beaker or a flask where there is plenty of room for gases to escape.

12. Never distill to dryness.

13. Use only round-bottom flasks or filter flasks for evacuation.

14.  Use extra caution in manipulating heated objects, especially ironware and glassware.

15.  If there is an accident, regardless of how minor, notify the instructor immediately.

16.  Eating or drinking is permitted only outside the laboratory.

17. Think while you work and use common  sense.  Never rush.

18.  Perform no unauthorized experiments.

19. Never work alone.

20. Further specialized instruction will be provided as specific experiments warrant.
