Course Web Access It is my intent to utilize Blackboard to post a variety of documents and information for you relating to the course. You will be able to view your grades throughout the semester in the Blackboard system, thus allowing you to track you progress in the course. You access Blackboard through the college MyYCP portal. Description This is the advanced version of the second semester in introductory chemistry. Topics include thermochemistry, gas laws, states of matter, solutions, chemical kinetics, equilibria, acid-base chemistry, buffers, ion equilibria in aqueous solutions, entropy, free energy, chemical spontaneity, and electrochemistry. When possible, examples from organic chemistry will be used to strengthen and prepare your background as you move forward in the chemistry curriculum. Prerequisite: Students should have successfully completed CHM 134 with a grade of 2.5 or greater. Required Materials It will be essential for you to have your own hand-held calculator (that can perform log functions and exponential notation) for homework, classwork, and examinations. If you are unsure your calculator meets the requirements, please see the instructor. Objectives It is an overall goal of this course to improve the problem solving and mathematical skills of all students enrolled. Oral and written communication skills should also be improved by the exercises in the laboratory portion of the course. In addition, students successfully completing this course should be able to: 1. quantitatively interpret the behavior of ideal gases 2. predict properties of liquids based on their molecular structure 3. use a phase diagram to discuss changes of state at different pressures 4. explain and interpret the effects of hydrogen bonds formed in water 5. deduce a rate law from experimental reaction data 6. use the rate law to determine concentrations of species at a specified time 7. explain the influence of catalysts on certain reaction rates 8. discuss reaction mechanisms and their connection to reaction rates 9. write and use equilibrium expressions for chemical reactions 10. calculate final concentrations of species involved in an equilibrium 11. predict changes to equilibria subjected to an external disturbance 12. predict the solubility of salts in aqueous solution 13. understand the ph scale and its application to acid-base chemistry 14. design and prepare buffers to control the ph of aqueous solutions 15. define the terms enthalpy, entropy, and free energy 16. apply the First and Second Laws of Thermodynamics 17. use Hess s Law and thermodynamic tables to predict the heat of reaction 18. predict the spontaneity of reactions using free energy data 19. relate free energies to chemical equilibria 20.understand the distinction in electrochemical cells and determine the appropriate use of each

Attendance Policy I strongly believe it is essential for you to attend class regularly it is one of the most important keys to your success in the course. Class attendance will not be used, however, as a criterion for evaluating student performance. If you are absent from class, it will be your responsibility to contact me before the start of the next class meeting if you wish to receive information about topics covered or important announcements that you may have missed. As college policy dictates, if you stop coming to class but fail to drop the course, I must notify the administration you may be at risk of losing on-campus housing and potentially any financial aid you receive in this event. Policy Concerning Personal Technology Devices While York College recognizes students need for educational and emergency related technological devices such as laptops, PDA s, cellular phones, etc., using them unethically or recreationally during class time is never appropriate. The college recognizes and supports faculty members authority to regulate in their classrooms student use of all electronic devices. Examinations There will be five closed-book examinations each worth 100 points. The lowest score among these exams will be dropped when computing the total course points. With the exception of the third exam, each exam will be given during either a lab period. Given the advance notice of exam times, students should not have the need to miss an exam; however, should you find yourself unable to attend an exam period, you must contact me in advance of the exam hour (by phone if necessary) in order to be excused. Excused absences will be granted only in the most extreme of circumstances (for the most part, a missed exam counts as your drop). A final, comprehensive examination will be given Monday, May 9, 2011, from 10:15 am 12:15 pm. Do not request to take the exam at another time due to travel conflicts you have ample time to arrange your travel plans accordingly. This will count as 150 points towards your final grade. All students must complete this exam (the score obtained cannot be dropped). Homework Accompanying your textbook should have been an access code to an online study system called Mastering Chemistry. You will be required to make use of this system in order to complete several homework assignments. In addition to the required materials the system contains many tutorials and practice problems that you can and should use to tailor your studying to the specific topics that you most wish to address. More information on accessing the system and submitting assignments will be provided over the first couple of weeks of the semester. The required homework assignments will allow you to earn up to 125 points towards your overall grade in the course. Laboratory Work This is a laboratory course. A separate syllabus will be distributed that describes this part of the course. Occasionally we will use one of the weekly lab sessions as an overflow to allow us to expand on topics covered in lecture. Lab is worth 325 out of the 1000 points available in CHM 146 this semester. Academic Standards York College s mission statement stipulates that strict adherence to principles of academic honesty is expected of all students. Therefore, academic dishonesty will not be tolerated at York College. Academic dishonesty refers to actions such as, but not limited to, cheating, plagiarism, fabricating research, falsifying academic documents, etc., and includes all situations where students make use of the work of others and claim such work as their own. When a faculty member believes a student has committed an act of academic dishonesty, the faculty member must inform the student in writing and then has ten business days from that written notification to the student to report the incident to the Dean of Academic Affairs and the Department Chair. Documentation related to instances of academic dishonesty will be kept on file in the student s permanent record. If the academic dishonesty is the student s first offense, the faculty member will have the discretion to decide on a suitable sanction up to a grade of 0 for the course. Students are not permitted to withdraw from a course in which they have been accused of academic dishonesty.

Writing Standards As recommended by the Faculty Senate and stated in the College Faculty Manual: York College recognizes the importance of effective communication in all disciplines and careers. Therefore students are expected to competently analyze, synthesize, organize, and articulate course material in papers, examinations and presentations. In addition, students should know and use communication skills current to their field of study, recognize the need for revision as part of their writing process, and employ standard conventions of English usage in both writing and speaking. Students may be asked to further revise assignments that do not demonstrate effective use of these communication skills. The Grade At the end of the course, each student will be assigned one of the following grades based on total accumulated points: Grade Points % Points 4.0 915 1000 92 100 3.5 865 914 87 91 3.0 795 864 80 86 2.5 755 794 76 79 2.0 695 754 70 75 1.0 575 694 58 69 0.0 0 574 0 57 W See below I See below How you ll earn the points: Exams 400 Final Exam 150 Lab 325 Homework 125 4 (Excellent): This grade denotes accomplishment that is truly distinctive and decidedly outstanding. It represents a high degree of attainment and is a grade that demands evidence of originality, independent work, an open and discriminating mind, and completeness and accuracy of knowledge, as well as an effective use of the knowledge. 3.5 (Very Good): This grade denotes mastery of the subject matter. It represents very good achievement in many aspects of the work, such as initiative, serious and determined industry, the ability to organize work, and the ability to comprehend and retain subject matter and to apply it to new problems and contexts. 3 (Good): This grade denotes considerable understanding of the subject matter. It represents a strong grasp and clear understanding of the subject matter and the ability to comprehend and retain course content. 2.5 (Above Average): This grade denotes above average understanding of the subject matter. It represents a good grasp of the subject matter and the ability to comprehend and retain course content. 2 (Average): This grade denotes average understanding of the subject matter. It represents the grade that may be expected of a student of normal ability who gives the work a reasonable amount of time and effort. 1 (Below Average): This grade denotes below average understanding of the subject matter. It represents work that falls below the acceptable standard. 0 (Failure): This grade denotes inadequate understanding of the subject matter. It signifies an absence of meaningful engagement with the subject matter and that the student is not capable of doing or understanding the work or has made little or no effort to do so. W (Withdrawal): Students are permitted to withdraw from courses without penalty up to the ninth Friday of the fall or spring semester. Corresponding deadlines are set for all other semesters (e.g., summer sessions). Withdrawal after that time shall result in a grade of 0. I (Incomplete): The student may request permission from the instructor to receive an incomplete prior to the final examination and must present extraordinary reasons for the petition. The Instructor should indicate on the Attendance/Final Grade Record the required work the student must do to complete the course. Any grades of I not removed within two calendar months after the end of the semester will automatically be changed to 0 in the Records Office. Grades of incomplete should only be provided to students who have completed a substantial portion of all course requirements.

Suggested Homework Problems: Each chapter of material covered in this course has a large number of problems for practice at the end of the chapter. The problems listed here represent an average sampling from each chapter, and I strongly recommend you work on at least some of these each day after class. Many of these problems are included as part of the assignments you will complete, for credit, using Mastering Chemistry however, when you see them online, many will likely have different numbers in them as part of a randomization that the program introduces. Competing the problems listed below prior to attempting your online, for-credit homework, should improve your proficiency and speed with which you complete the online homework. Also, note that your text pairs problems, so that in most cases each even-numbered problem is preceded or followed by a similar problem whose solution is available in an appendix at the back of the text. Thus, if you want extra practice or are unsure how to complete a problem, you might try its odd-numbered (or even-numbered, as appropriate) partner, as well. Finally, a complete solution guide is available in my office if you would like to see a detailed solution to any problem in the text. Problems that are bolded in the list below are included in the required, graded homework assignments. The dates/times indicated in parentheses are the due dates of each chapter s graded assignment.
