Tentative Schedule

 

Unit one                                Evaluation of Analytical Data                         5 Lectures

Unit Two                               Chemical Equilibrium                                         7 lectures

My expectation of you is the willingness to learn (this will make you inquisitive, ask questions, stay on top of assignments, critically and analytically read/study the textbook before and after class meetings, take notes during class, etc, etc, etc).

 

Assignments will be completed as specified in the course outline.  Late submission of assignment will be penalized at 5% for each class meeting cycle of lateness.

 

PROMPT ATTENDANCE IS REQUIRED. DOOR WILL CLOSE WHEN CLASS STARTS AND THERE WILL BE NO ADMITTANCE

 

Test: Unit tests will be given on the following dates

                                Unit one                                 Monday, September 14

                                Unit two                                 Monday, October 12

                                Unit three                              Monday, November 9

                                Unit Four                               Monday, December 7

 

Late Work Policy: Assignments received after the due date will be penalized by 5% for each class meeting cycle late and will be accepted no later than one week after the deadline. If you have a serious reason for missing a deadline or a schedule test, please notify me and arrangements may be made to accommodate your situation.

 

Grades: The final course grade will be distributed as follows:

                                                Unit tests                               80%

                                                Assignments                         20%

                                               

The letter-number grade equivalence for the course is as follows:

A+ 97-100             A 93-96                 A- 90-92                B+ 87-89               B 83-86                 B- 80-82

C+ 79-77               C 73-76                 C- 70-72                                D+ 69-67               D 63-66                 D- 60-62                F Below 60

 

Student Ethics

Academic dishonesty will be penalization according to the university’s regulations.  A copy the Indiana University’s “Code of Student Rights, Responsibilities, and Conduct” may be obtained from the office of the Vice Chancellor for Student Affairs. The Indiana University policy on academic dishonesty will be strictly adhered to and enforced when necessary.

 

 

Cell phones should be turned off or muted during the class period. Calls and text messages cannot be made or received during the class period.  You will be sent out of the classroom for this infraction.  No food or drinks should be brought into, or consumed during the class period.
