REQUIRED TEXT: Silberberg, Martin S., Chemistry, The Molecular Nature of Matter and Change, 5th ed., McGraw-Hill Higher Education, Boston, 2008 ANCILLARY MATERIALS: Aris ACC CRD Chemistry (online exercises) REQUIRED LAB MANUAL: Beran, J. A., Laboratory Manual for Principles of General Chemistry, 6th ed., John Wiley & Sons, Inc., New York, 2000 (must be an unused manual) COURSE DESCRIPTION & PURPOSE: Chemistry 112 is the second semester of a two-semester sequence of general college chemistry for science and engineering majors; it is transferable to all colleges and universities throughout the Commonwealth of Virginia and elsewhere for science, engineering, pre-medical, pre-dental, and pre-veterinary programs. It is not intended for nursing, other allied health majors, or to meet the general education science requirement for liberal arts, business, or other nonscience programs. Chemistry 112 is a continuation of Chemistry 111 and covers such topics as the chemistry of the solid and liquid states, solutions, kinetics, equilibrium, acid-base chemistry, thermodynamics, electrochemistry, and nuclear chemistry. Course objectives and a list detailing homework, lecture, and lab assignments and approximate test dates are available on my faculty website (accessible from NVCC’s web page under “Directories and Offices”) as well as on the Blackboard site for your section of this course, although the Blackboard site will not be activated until the first week of the spring semester. PREREQUISITE FOR CHEMISTRY 112: 1. Chemistry 111 with a passing grade (Chemistry 112 cannot be attempted before Chemistry 111). It is strongly recommended that students having a "D" grade in Chemistry 111 not continue in Chemistry 112 but repeat Chemistry 111. HOURLY EXAMS/FINAL EXAM: A minimum of four hourly exams will be given at regular intervals (see Approximate Lab/Lecture Schedule for approximate dates of the exams) throughout the semester. Exams will be administered during the last hour of a scheduled lecture period, and questions will be drawn from lecture discussions, homework problems, or the text—review all these sources. Questions will cover only material assigned and discussed in lecture in the interval since the previous exam. No questions concerning laboratory experiments will appear on any hourly lecture exam. HOURLY EXAMS CANNOT BE MADE UP IF YOU WERE ABSENT DURING THE EXAM PERIOD. THERE WILL BE NO EXCEPTIONS TO THIS POLICY. NO EXAM SCORES WILL BE DROPPED; ALL EXAM SCORES WILL BE INCLUDED IN THE DETERMINATION OF THE COURSE GRADE. The final exam will consist of approximately 65 multiple-choice questions. Approximately 60 of these questions will be drawn from the major lecture topics of each chapter in the course syllabus, AND AT LEAST 5 QUESTIONS WILL COME FROM ASSIGNED LABORATORY EXPERIMENTS. The test is strictly timed; a maximum of two hours will be allowed to complete the test. HOMEWORK/QUIZZES: End-of-chapter homework problems assigned for each chapter are listed on the handout titled APPROXIMATE LAB/LECTURE SCHEDULE. You are expected to work these problems on your own and to obtain assistancefrom the instructor during his office hours if you are experiencing difficulty with the problems or with other course material. These homework problems do not count toward the course grade; however, they may sometimes appear on an hourly exam. Additional homework problems are available in the Aris online exercises. Also check the Blackboard site for your class regularly for additional review and practice problems. THERE WILL BE OCCASIONAL POP QUIZZES IN LECTURE. EXPECT A QUIZ DURING ANY LECTURE PERIOD EXCEPT FOR THE FIRST CLASS MEETING AND DAYS WHEN HOURLY EXAMS ARE GIVEN. QUIZ QUESTIONS WILL BE DRAWN FROM THE LECTURE DISCUSSION OF THE PREVIOUS CLASS PERIOD OR FROM HOMEWORK QUESTIONS RELATED TO THE MATERIAL ALREADY DISCUSSED IN LECTURE. QUIZZES WILL USUALLY BE ADMINISTERED AT THE END OF THE LECTURE PERIOD. Note that QUIZZES CANNOT BE MADE UP IF ABSENT, NO MATTER WHAT THE CAUSE OR REASON. GRADING: All assignments and exams are graded on a point system. Lecture exams and quizzes account for 60% of the course grade, lab assignments and quizzes are worth 25%, and the final exam counts 15%. The course grade will be assigned according to the following end-of-semester averages: 88 – 100, A; 75 – 88, B; 60 – 75, C; 50 – 60, D; below 50, F. The instructor reserves the right to make arbitrary grade decisions only within borderline regions, which are regions of two points above or below the cutoff between two grade categories. NOTE: A “W” (withdrawal) GRADE WILL NOT BE ASSIGNED AFTER THE LAST DATE FOR DROPPING THE COURSE UNLESS THE STUDENT MEETS THE COLLEGE’S CRITERIA FOR EXTENUATING CIRCUMSTANCES PERMITTING LATE WITHDRAWAL. (Failing an exam or other assignments is not an extenuating circumstance.) The award of a “W” (withdrawal) grade after the last day to withdraw without grade penalty (March 26, 2010) requires official documentation and the signature of the Dean of the Math/Science/Engineering Division. It is the student’s responsibility to withdraw before the withdrawal deadline. The instructor will automatically withdraw only those students who registered for the course but did not attend at all during the first three weeks of the semester and those who quit attending during the first three weeks but failed to withdraw from the course. STUDENTS WHO QUIT ATTENDING AFTER THREE WEEKS MUST WITHDRAW THEMSELVES BEFORE THE DROP DEADLINE (March 26, 2010) OR THE INSTRUCTOR WILL ASSIGN THEM AN “F” GRADE AT THE END OF THE SEMESTER. AUDITING: AN “AUDIT” (“X”) GRADE WILL NOT BE AWARDED IN LIEU OF A WITHDRAWAL (“W”) GRADE. STUDENTS WHO HAVE REGISTERED FOR
