1.      Analyze kinetic data for reaction order, and write the rate law for chemical reactions based on experimental data.

2.      Demonstrate an understanding of the relationship of reaction rates to temperature, concentration, and activation energy.

3.      Explain the relationship between reaction mechanism and rate law.

4.      Perform calculations involving equilibria of weak acids, weak bases and buffers.

5.      Solve solution inventory problems for slightly soluble salts and complex ions.

6.      Analyze titration curves of weak, strong and polyprotic acids and bases to determine concentrations and equilibrium constant values.

7.      Calculate the Gibbs free energy  for reactions and interpret the relationship between entropy, enthalpy, temperature and spontaneity.

8.      Relate free energy to equilibrium constants.

9.      Demonstrate understanding of standard reduction potentials in relationship to electrochemical cells.

10.  Be able to calculate cell potentials to cells under non standard conditions.

11.  Solve quantitative electrochemical problems.

12.  Identify the components of an electrolytic or galvanic cell.

13.  Explain colors of transition metal compounds in terms of ligand field theory.

14.  Classify substances on the basis of their chemical reactivity.

15.  Describe different types of isomerism in organic and inorganic compounds.

16.  Analyze and balance nuclear equations.

17.  Demonstrate an understanding of the concepts of fission, fusion, transmutation, and natural radioactive decay.

18.  Classify organic compounds on the basis of structure and functional group.

19.  Name and draw structures for the major classes of organic compounds.

20.  Demonstrate proficiency in qualitative inorganic analytical techniques, computer data acquisition and analysis

Evaluation

Exams and Quizzes

There will be four exams and one final exam this semester.  The four exams will be given as per the schedule.  The final is comprehensive and will be given during our scheduled time in finals week.

Quizzes will be given every week that an exam is not scheduled.  It is very important for you to stay current and seek assistance when it is needed. 

It is recommended that you keep a file of all work done to use for study material and as a record of scores.

Laboratory

We will meet for lab two days a week.  It is important for you to read the experiment prior to coming to lab.  You must complete any pre-lab questions.  You will be given a lab quiz at the start of each new experiment.  Labs should be written up as formal labs reports.  Please see the guidelines at the end of this syllabus for the format.  If you have any questions, please ask.

Registration should be completed before checking into lab.  If registered late, bring your validated receipt to lab.  You are responsible for any lost or broken equipment in the laboratory and will be charged for all missing equipment at the end of the semester.  In a addition, a fee will be assessed for any student who fails to check out of the laboratory.

Homework

Homework problems from your text will be assigned and are to be completed in a 8½ x 11 spiral bound notebook with numbered pages. Make a table of contents using the first 1-2 pages and record the starting page for each homework assignment. Homework notebook will be checked in the laboratory.

Academic Integrity

The faculty and the college have determined that integrity and honesty are essential to the academic process and that it is necessary that the written materials submitted by each student in a class reflect his or her own work for that class.

ADACEMIC INTEGRITY POLICY

Submitting work as one’s own which has been done either all or part by another is defined as CHEATING.  Students found cheating will receive an “F” for the course.

“CHEATING” includes but is not limited to the following:

1.      The possession or use of unauthorized materials such as crib notes or unauthorized copies of exam material.

2.      Copying from another person’s quiz or exam or allowing another person to copy one’s examination material.

3.      Copying another person’s lab data and turning it in as one’s own or allowing another person to copy one’s data.

4.      Using a calculator or computer which contains stored information that can be used while taking a quiz or exam.

5.      The possession and/or use at the students work area of a personal communications device during exams or quizzes.

6.      Submitting a false report for work that was not actually done.

7.      Modifying or attempting to modify an answer on an exam after it has been returned and then claiming it was graded incorrectly.

We hope that each student will support this policy and realize the importance of honesty and integrity in his or her academic effort!

Cheating can result in any one of a variety of sanctions.  Such penalties may range from an adjusted grade on the particular exam, paper, project, or assignment to a failing grade in the course.  The instructor may also summarily suspend the student for the class meeting when the infraction occurs, as well as the following class meetings.  For further clarification and information on these issues, please consult with your instructor or contact the office of the Assistant Dean of Student Affairs.

ATTENDANCE:  Regular attendance is expected.  Excessive absence (3 absences) may result in being dropped from the class.

Grading

Those enrolled at the end of the semester must receive a letter grade unless they have chosen the CR/NCR option.  An “incomplete” may be arranged for completion of a particular item such as the final exam with sufficient cause.  Withdrawal or CR/NCR grading is available through admissions and records.

Grading Criteria

Approximately 89% will earn an A, 79 % a B, 65% a C and 55% a D grade.  Please note anyone with less than a 55% average on the exams, including the final, or the labs will receive an F.  Also, the final grade will be no higher than one letter grade higher than the exam average. All grades may be subject to a

 ( +/-) 1-2 % instructor evaluation of the student.  (Evaluation may be based on homework, class participation, etc.)

Additional Chemistry Assistance

There is a free tutoring service in the library.  Chemistry instructors are available to all students during “open” help times.  Chemistry 142T, the computer drill course is highly recommended.

Computer tutorials are available to anyone who registers for Chemistry 142T.  They are useful study tools and completion of 85% of these drills will earn 1 unit of credit. 

Student Accessibility

For accommodations due to a disability, please see your instructor within the first two weeks of the semester. Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and contact Disabled Student Programs & Services (DSPS) early in the semester so that reasonable accommodations may be implemented as soon as possible.  Students may contact DSP&S in person in Room 110 or by telephone at (619) 644-7112 or (619) 644-7119 (TTY for deaf).
