Rationale
CHEM 123 (along with its laboratory component, CHEM 124) is a continuation of CHEM 121. It builds on the foundation laid in CHEM 121 as well as introduces additional topics that help to set a strong chemistry foundation for science students.
Evaluation
Three(3) Hour Tests will be given (55% of final grade). In addition, 20 % of the final grade will be determined by homework assignments (WileyPlus). A comprehensive final exam (25%) will be given during the final exam period (see tentative syllabus).
For the purpose of this document, a make-up exam is defined as an exam which is different from the exam taken by the class on an announced exam date. If a student knows in advance that he/she cannot take the exam on the announced date, he/she should contact the instructor immediately to arrange to take the exam at another mutually agreed-to time. If, on the announced date of an exam, a student is unable to be present to take the exam, he/she must contact the instructor by telephone or email on that day. If arrangements can be made to take the exam before it is passed back to the class (usually the next class period after the exam was given), this is not a make-up. If the instructor is not notified of a student's inability to take the exam on the scheduled date or if the student fails to appear to take the exam at the agreed-to date and time, except in extremely extenuating circumstances, the student will receive a score of zero for the missed exam.
The Final Exam in this course will be comprehensive and will consist of two parts. The first part will require approximately one hour and will be a standardized multiple choice exam prepared by the American Chemical Society. This exam has national standards which will allow us to compare our students' performance with that of students nationwide. The second hour of the final exam period will be a exam prepared by the instructor in the format of the Hour Exams. The Final Exam score will be the average of these two exam parts.

Students are advised that the college operates a free tutoring program.
The schedule of chemistry tutors is not yet available but students who
feel that tutoring might be needed should contact the tutoring office in
the Student success Center. The time to seek tutoring is before one gets
in trouble in the course not after failing the first exam!
Habitual lateness for lecture or laboratory sessions reveals a lack of respect for the instructor and fellow students as well. All students are expected to be present in the classroom when the lecture is expected to start (10:10). Students who arrive late for lecture interrupt the teaching/learning process of the classroom. If you must be late for lecture due to an unavoidable circumstance, please enter the classroom quietly and sit at the nearest available desk.
All cell phones, beepers or other types of electronic devices must be turned off during class times! Students are not permitted to use cell phones or to text message in the classroom. Failure to heed these rules may result in disciplinary action in accordance with the College's policies concerning disruptive behavior. Notebook computers may be used in class only for the taking of class notes. The instructor reserves the right to request the student to show him the file containg the class notes taken at any particular time in the class period.
Course Materials
Chemistry: Matter and It's Changes , Fifth
Edition by Brady & Senese
WileyPlus Access Card
(may be purchased online at http://edugen.wiley.com/edugen/secure/index.uni)
Electronic Calculator (with exp or Yx functions)
Office Hours
All students are invited to avail themselves of the opportunity of meeting with the instructor during office hours. No appointment is necessary to confer with the instructor during these times. It must be stressed that some questions asked by a student during lecture may not be appropriately dealt with at that time as the time required to deal with a matter which is particular to only one student is time which is not available to the other members of the class. If the instructor asks a student to confer with him about a particular matter after class or during office hours, the student should not feel put-off but should take advantage of the chance to work with the instructor one on one.
Tentative Syllabus
Note: A number of short videos have been placed on my webpage (http://faculty.ccbcmd.edu/~rdrisko1/index.htm ). These videos will allow students to review concepts from CHEM 111 to get "up to speed" as we apply them to new situations in CHEM 123. There are also some videos on the first concepts we introduce in CHEM 123 -- in particular the relationships between the solid, liquid, and gas phase. Other videos will be added to this list as we progress to other topics throughout this semester.

Reading Assignments
Reading assignments for each chapter covered this semester are presented in the tentative syllabus. It is expected that students will read this material prior to the instructor’s going over it in lecture. This provides an opportunity for the student to anticipate which sections of a chapter may be troublesome and, hopefully, will stimulate questions as the material is presented in class. It should also be noted that the textbook provides complete solutions to many types of exercises assigned in the homework sets within the reading assignments. Such information provides an excellent resource and model for set-up and solution of the “classic” types of problems encountered in this course.
The homework assignments will be completed online using the WileyPlus interactive system. (A specific URL for access to this course and section in WileyPlus will be given in the first class. The assignments are listed above with tentative due dates. These online questions & Problems sets must be completed by the deadlines which will be set and will constiute 20% of the final grade. It cannot be emphasized too strongly that the homework constitutes the nucleus of material that the student is expected to know in this course. It is logical, therefore, that exam questions will be structured similarly to homework problems. In some situations items placed upon exams are taken directly from the homework!!
