Course Description:
        Chemistry 1A is the first semester of a two-semester sequence of general chemistry.
Students are expected to have some background in chemistry from high school or from
Chemistry 31. It is assumed that students have had some prior experience with formulas, the
periodic table, simple stoichiometry, simple atomic theory, and gas laws. The topics covered in
Chemistry 1A include stoichiometry, periodic properties, thermochemistry and thermodynamics,
atomic structure, bonding, gases, oxidation-reduction reactions, and liquids and solids.
        The course consists of two 75-minute lectures and two three-hour labs per week.
Attendance at both lecture and lab is expected. The course is rigorous and requires that students
keep up with the material by studying outside of class every day. There will be homework
assignments, lab reports, and exams. Lecture periods will be used to discuss new topics and to
solve sample problems. Lab periods will be used to conduct experiments and additional problem
solving and discussion.

Course Goals:
        My main goal for this course is for you to learn chemistry. More specifically, I want you
to learn how the physical phenomena of chemistry work at a fundamental level. That is, by the
end of this course, I want you to know what’s really going on in chemistry. Along the way you
will develop different skills that will help you in your academic career (and maybe in everyday
life). These include (but are not limited to) understanding the scientific method and scientific
thinking, using unit analysis to aid in solving problems, and balancing equations.

Required Materials:
    Text: Chemistry & Chemical Reactivity, 7th Edition; Kotz, Treichel, and Townsend
    Lab Manual: Laboratory Manual for Chemistry 1A, Staff
    Safety goggles approved for chemistry
    Electronic calculator with log functions
    Laboratory notebook with carbonless paper

Grading:

       3 exams @ 100 points each                     300
       Cumulative Final                              200
       Lab Reports (best 13 of 14)                   260
       Lab Practical                                 20
       On-line Homework (best 12 of 13)              120
                             Total points            900

      Lab Reports: This includes pre-lab assignments as well as lab reports. Reports must be
       written legibly in ink. If I cannot read it, I will not grade it. Failure to obey the safety
       regulations in lab will result in a grade of zero for the lab(s) involved. The lowest lab
       report score will be dropped.
      Midterm Exams: There will be three midterm exams. Exams will be given in lab and will
       have a normal time limit of two hours. See lab schedule for information.
      Final Exam: The final exam will be comprehensive and cumulative.
      Homework: Homework assignments are to be completed via the OWL online homework
       system. Online homework will usually be due the Tuesday after that chapter is covered
       in lecture. More information about OWL will be given in class.

Academic Honesty: Absolutely, positively NO CHEATING! I will not tolerate cheating in this
class. Each offense will result in a grade of zero for the exercise. Repeat offenses may result in
the student being placed on probation, suspended, or expelled.

Laboratory Procedures and Grading:
   1. The experiment should be read, any necessary data sheets prepared, and any pre-lab
       assignments completed BEFORE coming to lab. You are expected to be prepared to do
       the lab when lab starts.
   2. The pre-lab assignment for an experiment is dues as you walk into lab on the day of the
       experiment. NO LATE PRE-LABS WILL BE ACCEPTED. Pre-labs will count as part
       of the lab grade.
   3. Unless otherwise announced, lab reports are due one week after completion of the
       experiment. Late reports will be downgraded 10% for each day they are late.
   4. You must keep a lab notebook (with carbonless copies) as a record of what you do each
       lab period. You must turn in the copy at the end of each lab period.
   5. For experiments which involve observations only, the observations may be recorded in
       ink directly into the appropriate places in the laboratory manual. The lab report for such
       experiments will consist of these pages plus any post-lab questions.
   6. Lab reports for all other experiments are to be written in ink in your lab notebooks and
       the copy of this report is to be turned in. A lab report must include the following:
           a. Your name, the date, and the TITLE of the experiment
           b. Names of any partners, number of your unknown (if applicable)
           c. Purpose (Abstract): A one-sentence description of the purpose of the experiment.
           d. Procedure: Read through the lab and write a short paragraph describing the
               procedure. The paragraph must be completed before lab period—the instructor
               will check the procedure section before you begin working on the experiment.

          e. Data and observations: Whenever possible, data should be arranged in tables. All
             tables should be neatly labeled to clearly identify them. Be sure to include units
             and the correct number of significant figures. Tables for data can be set up before
             you come to lab. Give a brief discussion of observations such as colors, odors,
             and appearance of solids.
          f. Calculations and balanced equations: One sample calculation of each type of
             calculation performed should be shown. Set it up clearly to identify it.
          g. Results and conclusions: Summarize the results of your experiment. If several
             runs were done, put values in a table along with the average value. Discuss errors
             that you are aware you made while performing the experiment and state how
             these errors would affect your results. Also analyze in general the experiment for
             errors. In experiments that are not quantitative summarize major principle
             learned.

Other Important Information:
    Turn off your cell phones and/or pagers during lectures and exams.
    You are expected to attend lectures and labs and to be on time. If you choose to be
       absent from lecture, be aware that you may miss important announcements and
       information that may affect your grade.
