Course Description:
Chemistry 112 is a survey of the principles of inorganic chemistry with strong emphasis on those fundamentals of chemistry which are essential to the understanding of organic and biological chemistry.  For students who need a broad introduction to the field of inorganic chemistry.  Not for science majors.  A student receiving credit for graduation in this course may not receive credit toward graduation in CHEM 100 or CHEM 120.  General Chemistry Lab I, CHEM 112L, is required as a corequisite.  A mathematical proficiency is expected.

A list of topics to be taught is included in the associated schedule for your reference.

Textbooks and Materials:
General, Organic, and Biochemistry, Stoker 4th Edition, 2008.

Reading Assignments:
Specific page assignments are listed in the course schedule
Teaching Methods:
Teaching methods include lectures, demonstrations, assigned readings, problem and writing  assignments and exams.  I strongly encourage class discussions to extend and clarify the lectures and readings. Teaching as well as learning is an interactive process.

Self study is an important part of the class. As a rule of thumb, you are expected to spend at least two additional hours for every hour of lectures. Any questions raised during the self study can be discussed in the class or in my office. 


Exams:
There will be three exams and a comprehensive final. Questions may come from lectures, assigned readings, and discussions. Questions may include definitions, short answer, short essay and multiple choice. Most questions will be over material covered both in lectures and reading.

Any questions or unjustified grades can either be discussed during office hours the week following the return of the assignment. Should you miss one or more exam due to illness or University-related activities, inform the instructor in advance. It is your responsibility to schedule an alternative exam date as soon as possible.

Exams and other graded assignments must be accomplished independently, except as noted by the instructor. 


Grades: Lecture and laboratory scores are combined and the same letter grade is assigned for each student. The exams, quizzes, and final exam from the lecture portion of the course account for 67% of the grade and the laboratory reports account for 33%. Students are evaluated by their performance on three exams (100 points each), ten short quizzes and problem assignments (100 points), six laboratory reports (20 points each), and a  final examination (150 points). The approximate grading scale will be as follows:

The final grade will be assigned based approximately on the grading scale:
                 >90                 A
                 >80                 B
                 >70                 C
                 >60                 D

The instructor reserves the right to adjust this scale as necessary. I may adjust the scale downward but I will not adjust it upward. There will be no allowance for "extra credit." Examinations are typically "curved" in that I adjust the high to 100 for use with the 90-80-70-60 grading scale. Study guides and review questions will be made available and responsible students will prepare themselves accordingly. You should expect a quiz about every class period, which you will have about five minutes to complete. In addition, at the end of every class period you will be given a question over the material covered. You will turn in the answer to that problem at the beginning of the following class period. No late answers will be accepted. Some of these assignments, chosen at random, will be graded and used as quiz scores. 


Class Evaluation:
In addition to completing the formal course rating materials at the end of the semester, I would appreciate any informal suggestions and comments. 
Other General policies:
University Policies — Students in this class are expected to abide by the Fort Hays State University Academic Honesty Policy.  This policy may be found on page 61 on the Fort Hays State University 2002-2005 University Catalog.  Fort Hays State University students have the right to appeal grades that are assigned in all courses.  The appeal procedure is described beginning on page 59 on the Fort Hays State University 2002-2005 University Catalog. See also page 64 of the 2005-2008 Catalog.

Attendance -- Attendance is expected and recorded, but it is not used in the evaluation of students. The attendance is recorded on a sign-up sheet passed through the class. This is an official document and serious consequences will befall those who sign another individuals name.

Behavior -- I expect students at FHSU to act in an adult, socially-responsible manner. The groundwork you are laying for yourself now will determine your path through the remainder of your life. I expect, therefore, that you will retain academic integrity (not cheat or plagiarize). I specifically retain the right to discharge from the classroom any student engaging in socially irresponsible or disruptive behavior, including, but not limited to: talking, eating or drinking, violent behavior,  sexual harassment or disorderly conduct, as defined in your student handbook.  The following is a reproduction of that statement :

"Disorderly conduct, individual or group behavior which disturbs individuals or groups, is prohibited. Such conduct includes (but is not limited to) assault, threats to the personal safety of one's self or others, throwing objects to create a danger, making excessive noise, unwelcome physical contact, hazing and any other type of interference with the normal operations of the university or its activities or any type of conduct that interferes with the ability of those who attend, visit or work at the University to enjoy the benefits of the purposes for which the University exists"
When confronted with an "included but not limited to" list such as this, how do you know what you are allowed to do?  I suggest the following rule of thumb.  When you are thinking of doing or saying something, ask yourself "If I were at home and did or said this, would my mother yell at me?"  If the answer is yes, don't do it.

Special Note after replacement of carpet. This is a mediated classroom, and University policy forbids food or drink within. I have been lax about enforcing this rule but the carpets have just been replaced and I will be much more sticky about the policy. Please leave your snacks and beverages put away. Thank you.

Cell phones — The use of cell phones in this classroom is expressly forbidden. I reserve the right to discharge from the classroom anyone whose cell phone rings. Do not leave the classroom to take a call and come back in (or any other reason).

E-mail — I encourage you to contact me by email for various reasons. I would ask that you include [Chem 112] in the subject line to ensure I recognize the importance. Also, if you want a reply please say so in the email.

Makeup work -- Makeup exams are given to deserving students provided I am notified prior to the exam and arrangements are made within a reasonable length of time (one week after returning to class). Students are not allowed to makeup quizzes except in those cases where students miss a large number of quizzes for legitimate reasons. Students who miss quizzes may drop those provided they do not miss an excessive number.  Students are allowed to make up laboratory work provided that the laboratory work is made up within one week. There is a limit of two makeup labs per semester.

Grades of incomplete -- Grades of incomplete are recorded in those cases that comply with the current University policy. This policy states that for an incomplete to be given, work that has been performed must be of passing quality, and that if the incomplete work is not finished within 1 year the grade changes to "NC." Note, however, that I have the discretion as instructor to mold this policy. In particular, I am likely to give less than one year to complete the requirements, and a grade will be assigned at the end of the time period. The consequence of this is that if you do not complete the work, you will quite possibly fail the course.

Required laboratory materials -- Goggles and aprons are required in the lab for safety reasons. In addition, lab descriptions and prelab exercises are sold as a "lab packet."  These materials will be available during the first lab period. If you have goggles or an apron from a previous lab experience you can use them, but labs have been revised and different prelab exercises are used each semester; therefore, you must buy these.

The laboratory exercises are coordinated with the lecture material. Laboratory experiments are chosen to reinforce concepts which have been discussed in lecture. The weekly, two-hour laboratory begins with a brief prelab discussion. Time for students to complete the laboratory report is provided. All laboratory reports are due at the conclusion of the laboratory period.
