Relationship to Academic Development Programs and Transfer: CHEM 162 is not an Illinois
Articulation Initiative (IAI) approved transfer course (because to meet your science requirement, you must take one
physical science and one life science course), however, this course should transfer to most institutions as an elective.
Students should consult with an academic advisor for transfer information on this course in regards to particular
institutions. Refer to the IAI web page for information as well at www.itransfer.org
Course Objectives (Learning Outcomes): This is a continuation of the first semester general chemistry
course, with an even greater emphasis placed on problem-solving and problem-solving techniques (PS2, PS3). By
the end of the semester, the student will have a complete background in all areas of inorganic, physical, and organic
chemistry. This will be achieved by being proficient in:
 Analyzing the kinetics of reactions.
 Applying the concepts of equilibria and solving general equilibrium problems.
 Distinguish and relate the equilibriums of weak acids and bases including buffer systems.
 Relate the solubility product and complex ion equilibriums.
 Describe the thermodynamics of reactions including its relationship to equilibrium.
 Describe an electrochemical reaction and its related processes.
 Demonstrate an understanding of nuclear reactions and explain the energies associated with them.
 Define various organic molecules and predict their reactions.
 Understand the role of the functional groups in biochemistry.
 Characterize the chemistry of the non-metals and metals.
 Describe the chemistry of transition metals complexes and relate that to Crystal Field Theory.
A three-hour laboratory exercise each week will reinforce the lecture material and help to illustrate some of the
concepts from above. Since problem solving is the single most important aspect of this course, it will be
emphasized in all homework assignments, quizzes, and tests.

Methods of Instruction: My philosophy is to present the lecture material as straight forward as possible, with an
emphasis on problem- solving techniques. Memorization of formulas, weights, chemical symbols, etc. is not
required, as I will supply these for you on the tests. Also, I will present and use many mathematical operations
during the semester that you are expected to know. If you should have a problem of a mathematical nature, then you
are encouraged to visit the ASC. Further, I try to treat all students with the utmost respect during and out of class
and expect the same in return. Lastly, I am always available before and after class and have office hours scheduled
during a variety of times – DO NOT be afraid to stop in and ask a question even if I look “busy.” My first priority is
always to those students who are putting forth effort in the classroom.
Course Policies:
Method of Evaluation (Tests/Exams, Grading System): Grades will be determined by a combination of
worksheets, tests, lab work, and a portfolio as follows:
Worksheets / Quizzes
= 150pts.
Exams, 4 @ 100 pts each*
= 300pts.
Labs
= 200pts.
Special Topic
= 50pts.
Portfolio
= 100pts.
Final Exam
= 200pts.
1000pts.
*lowest exam is dropped
Grades are all based on a 90.00 – 80.00 – 70.00 – 65.00 scale. However, your overall lecture average must be
greater than 65% to obtain a D, 70% to obtain a C, 80% to obtain a B, and 90% to obtain an A. Also,
successful completion of the lab and the portfolio is REQUIRED for passing the course.
Attendance: I will be keeping track of attendance. Anyone missing more than 25% of the lectures (8 periods) will
fail automatically. There are NO excused absences – if you are not here for any reason, then you will be counted as
absent. In addition, anyone more than ten minutes late will be receive a one-half absence. Also, due to state
requirements, I am required to certify at mid-term that each student is attending and/or making progress towards
completing the course. Thus, if you have either missed many classes and/or assignments at that point, then I will
assign a grade of “W” at mid-term. Attendance in the lab is required. If you know that you must miss a lab
exercise, please let your instructor know.
Homework: Homework material is assigned as we begin each chapter and is completely OPTIONAL, but is
encouraged for your portfolio. While no credit will be given for this material, it is a portion of your portfolio grade.
Also, these problems serve as additional examples and are usually similar to many of the quiz and exam questions.
For that reason, completing the supplemental homework will increase your success on exams.
Worksheet format: All of the worksheets are take-home exercises and are due within a week after you receive
them. Partial credit is given on all – so show all of your work. Late work is accepted for up to one week after the
initial due date (exception is the last worksheet) with no penalty. If you need an extension beyond this time, please
talk to me.
Quiz format: The quizzes will be based on current homework problems. There are eight regular in-class quizzes
(best six will count) and four group quizzes. You will be allowed to use your notes on all quizzes. As with the
worksheets, partial credit is given and make-ups are allowed if done within a week.
Exam format: The exams will consist of 32 questions in a multiple-choice style. Note that no partial credit is given
in this type of format! Each exam is designed to challenge your ability to think and show what you have learned to
the fullest. Each exam is curved to fit a 90 - 80 - 70 - 65 scale. No make-up exams are given – you are expected to
be present on the day of an exam. If you know that you will miss an exam for any reason, then you must contact me
in advance to make alternative arrangements if possible.
The Problem-Solving Portfolio: You are required to keep a problem-solving portfolio for this class. You will be
given a separate page of instructions as to how to put this together, however, this portfolio will include all of your
lecture problems, assignments, quizzes, and exams. The portfolio is mandatory for passing the course.
Special Topic: An oral / written report will be assigned for this course on a current science topic of your choice (the
"Special Topic"). This will be further explained in a supplemental to this syllabus.
Incompletes: In general, incompletes are only given in rare circumstances. These must be approved by the
instructor.
Make-Up Policy: No exam or lab make-ups are allowed. If you know that you will miss a exam or lab in advance,
then please talk to your instructor as far in advance as possible.
Required Writing and Reading: This course will cover approximately 500 pages of text from both the lecture and
lab over a sixteen-week period. While in many cases students may not need to read the text on some topics, reading
the topics either before or immediately after the lecture is strongly recommended. One formal written laboratory
reports will be required for the lab and a written paper over the special topic assignment is also assigned.
Telecommunications Policy: Please practice good cell phone etiquette by either turning off or putting your cell
phone into a silent mode before the start of each class session. Repeat offenders may be dismissed from a class
period after an interruption.
Academic Integrity and Plagiarism:
Academic Integrity: Academic integrity is a fundamental principle of collegial life at Heartland Community
College and is essential to the credibility of the College’s educational programs. Moreover, because grading may be
competitive, students who misrepresent their academic work violate the right of their fellow students. The College,
therefore, views any act of academic dishonest as a serious offense requiring disciplinary measures, including course
failure, suspension, and even expulsion from the College. In addition, an act of academic dishonesty may have
unforeseen effects far beyond any officially imposed penalties. Violations of academic integrity include, but are not
limited to cheating, aiding or suborning cheating or other acts of academic dishonesty, plagiarism, misrepresentation
of data, falsification of academic records or documents and unauthorized access to computerized academic or
administrative records or systems. Definitions of these violations may be found in the college catalog.
In this course, there is a fine line between cheating and working collaboratively. On worksheets and (group)
quizzes, you are strongly encouraged to work together to collaboratively solve problems. This means that you
should work together, step-by-step, until you arrive at a solution or work independently and then compare work at
the end. The line is crossed, however, when you directly copy someone else’s work without bothering to learn
“how.” In summary, GOOD: seeing students comparing answers before the start of class or working together in a
study area and BAD: walking in to class while a student is copying the work of someone else’s worksheet. Note – if
you are the person who is letting another student copy your work, then you are an ENABLER and are just as guilty.
Finally, the penalty in my course for cheating on an exam is dismissal from the course with a final grade of an “F.”
In addition, I may place a letter in your permanent file here at HCC. Note that you do have the right to appeal this
decision based on the appeals process found in the student handbook.
Plagiarism: Plagiarism is the presenting of others' ideas as if they were your own. When you write a paper, create a
project, do a presentation or create anything original, it is assumed that all the work, except for that which is
attributed to another author or creator, is your own. Plagiarism is considered a serious academic offense. For your
papers assigned in this course, instances of plagiarism will result from a zero for the entire assignment to a failure
for the entire course. See your student handbook for more information regarding this topic.
Support Services:
Heartland Library Information: The Library, located in the Students Commons Buildings at the Raab Road
campus, provides Heartland students with a full range of resources including books, online journal databases,
videos, newspapers, periodicals, reserves, and interlibrary loan. Librarians are available to assist in locating
information. For more information please call the Library (309) 268-8200 or (309) 268-8292

the Academic Support Center (ASC) in Normal and at the Pontiac and Lincoln Centers. Tutors are available at
convenient times throughout the week. Study groups, group tutoring facilitated by a specially-trained tutor, are also
available by request. For more information about services available at each location, please call the ASC in Normal
(309) 268-8231; the Pontiac Center (815) 842-6777; the Lincoln Center (217) 735-1731.
Testing Center: Testing Services provides a secure testing environment for students who are enrolled in online,
hybrid, and other distance learning courses; have a documented disability; or need to take a make-up exam. Testing
accommodations for students having documented disabilities must be arranged by the student through the Office of
Disability Services, and Testing Services will only administer make-up exams at the request of the instructor.

Lab Outline
Description:
The lab will consist of 15 exercises relating to the material in the book.
Required Textbook / Materials:
General Chemistry 162 Laboratory Manual, by Muench
Safety Glasses (Yours or ones supplied by HCC)
Scientific Calculator
Lab content:
Each week will begin with the students turning in their completed pre-lab assignment. A brief
explanation of the lab procedures for that particular week will follow. Once that has been
completed, you will proceed with that week's lab exercise to completion. Unless instructed
otherwise, all work is to be completed during the lab period and turned in that day.
Grading:
Grades will be determined by a combination of lab work and the lab final. The lab point values
will vary according to the difficulty of the exercises. The total number of points will be 200 or
20% of your overall grade at the end of the semester. There will be one laboratory report to be
completed in the semester.
Attendance:
Your attendance is mandatory for the lab section. There will be no opportunity to make-up a
missed laboratory assignment. Anyone missing more than two lab periods can fail the entire
course. If you know that you will need to miss an exercise for any reason, please let the
instructor know as far in advance as possible.
Lab Report:
One lab report will be assigned for this class and it is the third lab. You will be given
instructions in how to write this report in class. The lab report is due two weeks after the
conclusion of the lab activity for full credit. Any late lab reports up to the end of the semester
will be penalized 20% (5pts.). Students also have the option of turning in the data with complete
calculations only for a maximum of 10 of the 25 points possible.
Lab Final:
There will be one lab final at the end of the semester. This final has both a written and hands-on
component. The written part will be based on eight of the lab exercises previously completed
and you will only need to answer four of those questions. The hands-on portion will be based off
of the Qualitative Analysis from earlier in the semester and will require each student to identify a
total of four ions – one from each of the groups. A time limit of three hours is strictly enforced
for the combined written and hands-on exercise.
