Required text: CHEMISTRY The Central Science, 12th ed. by Brown, LeMay, Bursten, Murphy and Woodward
Optional text: Study Guide to accompany CHEMISTRY The Central Science

This course is a continuation of CHE104 and will provide an opportunity for each student to learn about, and become skilled at applying, the following concepts: Physical properties of matter (including states of matter, phase changes, intermolecular forces, etc.), thermodynamics, kinetics, and solution chemistry (including solubility, colligative properties, equilibrium, acid-base reactions, etc.). A class schedule is given below. The text provides details as to how these concepts will be presented.

The objective of this course is to provide you with an opportunity to gain a basis of principles, concepts, and reasoning skills that will allow you to explore and better understand the world we live in. This course will also provide a sound beginning for future work in chemistry and the sciences. Understanding chemistry depends on a good working foundation. You are well advised to learn all you can from this course since this is where that foundation is obtained.

Chemistry is also an excellent opportunity to work on the college-wide competencies listed on the page titled Academic Assessment at Rivier. The nature of chemistry requires you to apply an understanding of course content to solve a variety of problems. In the process you will need to think critically and synthesize concepts. It is also an opportunity to make judgments about the appropriateness of solutions, not only in a physical sense, but often in more global ways. The ability to communicate will be important when explaining concepts and working in groups.

Feel free to ask questions during the "lecture" period or at any other time. It is a general rule in chemistry that if one person doesn't understand, there are at least three or four others who also don't understand.

Homework problems are shown on a separate sheet. Homework from the text will not be collected, but a quiz will be given at the beginning of the laboratory period covering the text homework up to that point. One quiz will be dropped when calculating the quiz average. The quiz average will contribute to the lecture grade.

Four exams will be given during the semester. Exams will not include true-false or multiple choice questions but will include problems similar to homework problems and exercises done in class and in the laboratory. There will also be a comprehensive final exam.

Final grades will be determined using the following scale:

Exam Average 65%
Quiz Average 15%
Comprehensive Final Exam 20%

Letter grades will be assigned as established by the college (see page titled Academic Assessment at Rivier). For example, if a student had an exam average of 86%, a quiz average of 81%, and a final exam score of 78%, she would have a final score of

(.15)(86) + (.65)(82) + (.2)(77) = 81.6

and receive a B- in the course.

The class homepage also has other resources to help clarify the topics covered in class as well as a link to Academic Policies at Rivier and for this class. On our class policy page (http://www.rivier.edu/chemistry/policies/) specific statements have been extracted, from the policies common to all undergraduate courses at Rivier College (http://www.rivier.edu/undergradcoursepolicies.), on Attendance, Habitual Non-Attendance, Academic Assessment, Academic Honesty, Classroom Behavior, Electronic Devices and Students With Disabilities. You are expected to be familiar with these policies and adhere to them.

GENERAL CHEMISTRY LABORATORY, CHE105L, Spring 2014

Instructor: Dr. David R. Burgess, dburgess@rivier.edu, http://www.rivier.edu/chemistry

Text: No text is required, but each student is required to use a bound laboratory notebook.

The second semester chemistry laboratory will focus on problem solving, critical thinking and logical reasoning in scientific experimentation. In addition the laboratory will provide each student the opportunity to re-enforce the topics covered in lecture and extend their chemical knowledge base by:

1. "In class" laboratory experiments (each count as a separate laboratory assignment). These will be given as the semester progresses. In general the laboratory reports will be due one week after the experiment is completed. Late laboratory reports will receive grade reductions*.

2. Short argumentative paper. Write a paper convincing the instructor that one of the pieces under "Chemical Applications and Essays" is the most interesting piece. These are listed, with page numbers, just after the Table of Contents in your text book (p. xxiv). Write the paper using the format given on the website. This will count as one laboratory assignment and is due on 14 February. See the web page for more details. Consider this as a practice paper for #3 below.

3. Critical thinking assignments concerning the environment. Use Chapter 18 of your text as a beginning resource to identify the environmental concern that should be the number one priority for us today. Write a document to convince President Obama of your choice of the number one environmental concern. In other words, write a sound argument for your position using the prescribed format. A first draft (not a rough draft) will be required on 4 March and will count as one lab assignment. A second draft will be due 1 April and count as a second laboratory assignment. See our web page for more details.

4. Internet assignment (counts as one lab). This internet assignment will be due on the same day as the first draft of the environment paper. Evaluate at least three internet web sites dealing with the environmental concern that you chose for assignment #3. The evaluation should include the following (give some explanation. No yes or no answers!): (a)The URL of the site. (b)Is the source reliable? How do you know? (c)Is the information helpful? Explain. (d)Was finding the reference easy or difficult? Explain.

The final grade will be determined by averaging all of the assignments given during the semester. Each assignment will carry equal weight.

All data should be recorded in a bound laboratory notebook. It is also a good idea to write a preliminary report in your notebook, before doing the experiment, when possible. A separate report, based on the notebook material, is required for each student. The reports are due one week after completion of the experiment or as assigned. Late reports will be penalized*. Some reports may require a modified format. This will be discussed in class for each laboratory or exercise. It is expected that all written material will be grammatically correct. A word processor should be used (equations and the like can be hand written).

All students are required to know and abide by the safety rules for the laboratory as explained in class and summarized in the document "Safety In The Chemistry Laboratory."

*Late assignments: There will not be any penalty for up to three late lab assignments. If there are four or more late assignments at the end of the semester, all of the late assignments, including the first three, will be penalized 20% when calculating the final grade. Only the late assignments will be penalized and this will be done when final grades are calculated, after the assignments have been graded (all assignments will be graded as if they came in on time).

Most laboratory reports should be organized as follows:

  1. Date, Name, Title
  2. Objective or Purpose of the Experiment
  3. Theory (What principles are needed in order to understand this lab?)
    1. Underlying Concepts
    2. Mathematical Models
  4. Materials Needed
  5. Procedure
  6. Tabulated Data and Result
  7. Error Analysis. (How confident are you in the result? What is the +/- value? Where does it come from?)
  8. Implications (Where could this be used?)

Safety In The Chemistry Laboratory

Whenever anyone is in a chemical laboratory they must use caution and observe some basic rules. Most of these are common sense, but they must be strictly adhered to in order to keep the laboratory safe.

1. Always wear safety glasses. No one is allowed into the laboratory without eye protection. If there is a spill use the eyewash immediately, before the material runs behind the eye protection. If chemicals come in contact with the skin, immediately wash with copious amounts of water and inform the instructor. Always inform the instructor of any accident.

2. Food and drinks are not allowed in the laboratory. No smoking, drinking, eating, or chewing is permitted at any time in the lab.

3. Shoes must be worn in the laboratory at all times.

4. Secure loose clothing and hair while working in the lab.

5. Dispose of chemicals as instructed.

6. Never taste anything or directly smell the source of any vapor or gas. Use the hood as instructed.

7. Never point a test tube that is being heated at yourself or anyone else.

8. Clean up all broken glass immediately. Inform the instructor whenever anything is broken.

9. Always pour acids into water. Doing it the other way around can produce a lot of heat and cause spattering. Be especially careful with sulfuric acid which is more dense than water and may sink under the water, build up heat, and spatter. Always slowly pour the acid into the water while stirring constantly.

10. Never pour "extra" chemicals back into the original containers.

11. Never work alone in the laboratory.

The laboratory can be a safe place. It is expected that everyone will be serious and attentive while working in the laboratory.
