Required Materials: Chemistry Principles and Reactions, 6th Edition; by William L. Masterton
and Cecile N. Hurley, 2009; Brooks/Cole Cengage Learning
OWL access
A scientific calculator (one that can do exponents)
Prerequisites: CHE 141 – General Inorganic Chemistry I.
Disclaimer: Although we expect to conduct the course according to the following, we reserve
the right to make modifications if circumstances dictate.
Course description: Lecture three hours per week. Laboratory meets three hours per week.
This course is a continuation of CHE 141. The fundamental laws and theories of chemistry and
chemical calculations are stressed, primarily while studying inorganic compounds.
Rationale for course: This course will provide a general understanding of chemistry for the
non-science major as well as a foundation in chemistry for future study for the science major.
Development of problem solving and critical thinking skills will be stressed.
Notice: No cell phones should be powered on while in class. Use of cell phone calculator
function is not allowed, rather, student should acquire a general scientific calculator that is able
to handle exponential and log functions. Graphing calculators can be used, but are not required.
The memory function of such calculators shall not be used to store formulas, equations, etc.
that if written on paper would be called a “cheat sheet”.
Attendance: Your attendance at all class meetings is expected. Please refer to the 2010-2011
Mississippi College Undergraduate Bulletin. An accumulation of 8 absences results in an
automatic F in the course. Roll will be checked each day. If a regular class meeting is missed, it
is the student=s responsibility to obtain any assignments or instructions that were given by the
instructor. Missing a class is not an excuse for not preparing for the next class meeting or not
having an assignment ready on time. Don=t miss a scheduled test! In the event of an extreme
emergency and an excused absence, a make-up test will be given. The test must be made up
prior to the graded tests being returned to the class. NO MAKE-UP TESTS WILL BE GIVEN
AFTER THE TESTS HAVE BEEN RETURNED. The last day to drop this class is Friday,
March 25, 2011.
Methods of Instruction: Class will consist primarily of lectures and working problems.
Appropriate demonstrations as well as laboratory activities may be done to reinforce key
concepts
Methods of Evaluating Student Progress: Three tests will be given during the semester, each
with a value of 100 points. Exams may contain essay questions that require the student to
express thoughts in a well-organized manner consistent with accepted writing form.
Unannounced pop tests are given periodically, the total number of pop test points will be
approximately 100. Pop tests that are missed are not made up. The final exam is comprehensive
and is worth 150 points. Each chapter will have homework problems assigned from the text that
should be completed as soon as the material is covered in class. Occasionally there are
opportunities for extra credit points by attending a special seminar or a visiting lecture. The
laboratory portion of the class is worth 200 points, and is combined with the points earned from
the lecture portion of the class in determining the final course grade. The grading scale for this
course is based on the percentage of total points earned in the course, and is as follows:

Tutorials: There will be a scheduled help session each Monday from 4:00 until 5:00 pm. It will
be held in H312. It is most efficiently run if you will bring specific questions or problem types
to the session.
Tuition refunds: The last day to drop a class with 100% refund of tuition is January 20.
Special Accommodations: In order for a student to receive disability accommodations under Section 504
of the Americans with Disabilities Act, he or she must schedule an individual meeting with the Director
of Student Counseling Services immediately upon recognition of their disability (if their disability is
known they must come in before the semester begins or make an appointment immediately upon receipt
of their syllabi for the new semester). The student must bring with them written documentation from a
medical physician and/or licensed clinician that verifies their disability. If the student has received prior
accommodations, they must bring written documentation of those accommodations (example
Individualized Education Plan from the school system). Documentation must be current (within 3 years).
The student must meet with SCS face-to face and also attend two (2) additional follow up meetings (one
mid semester before or after midterm examinations and the last one at the end of the semester). Please
note that the student may also schedule additional meetings as needed for support through SCS as they
work with their professor throughout the semester. Note: Students must come in each semester to
complete their Individualized Accommodation Plan (example: MC student completes fall semester IAP
plan and even if student is a continuing student for the spring semester they must come in again to
complete their spring semester IAP plan).
Required Practices: You are expected to read the appropriate sections of your text and work any
problems assigned before coming to class. Periodically throughout the semester, a quiz will be
given on the reading and/or problems assigned which will be part of your daily grade (as
discussed above).
Academic Integrity: University policy 2.19 clearly defines the behavior that the college
considers academically dishonest (also see 2010-2011 Mississippi College Undergraduate
Bulletin). Students are expected to conduct themselves as professionals. If dishonest behavior is
detected, it will be reported to the appropriate administrator and the student will receive no credit
for the work.
Laboratory: Laboratory is operated almost independently of the class, and has its own
supplement to this syllabus. The laboratory and class grades are merged to determine the
overall grade, as explained above.
Course Outline & Learning Objectives:
Topics
Learning Objectives
1. Intermolecular forces,
liquids, and solids
The student will have a general understanding of
intermolecular forces and how they relate to the phases of
matter.
2. Thermochemistry
The student will have an understanding of enthalpy and the
First Law of Thermodynamics.
3. Solutions
The student will be familiar with solution concentration
units, the principles of solubility and colligative properties.
4. Rates of Reactions

CHEMISTRY 142 ELECTRONIC HOMEWORK
Section A
(Mr. Benton)
The OWL online homework and extra credit work can be done on your personal computer or any
other computers where you can get online, such as in the Hannah Chemistry Computer Lab
(Hederman Science 409). Chemistry 142 students are only allowed to use the computers on the
east and north walls of the room. The computer room is usually available for CHE 142
students from 8am to 1:30 pm Monday-Thursday, 5pm-6pm Monday-Thursday, and all day
Friday. Please plan your schedule carefully so you are not in trouble as the assignments are
due. Other times are possible except when a class is in progress.
When you use the information included in your textbook package you will be able to get online and
see your assignments. Points scored on the homework and on the optional extra credit will be added
to your total point score and counted like any other points. The values of extra credit points will be
modified and that will be explained at a later date in class. Assignments will be added throughout the
semester.
A very important part of this chemistry course is working problems and practicing conceptual
exercises. Practice is how you become proficient at any new skill. Homework is how we practice!
The OWL online computer exercises are an excellent source of practice problems with immediate
feedback to let you know if you are on the right track. I urge you to work as many as possible of the
suggested extra credit or optional exercises in the chapters.
