1 MONTGOMERY COLLEGE Chemistry Department Rockville Campus Summer II 2015 CHEM131-: General Chemistry I Lecture Section (10462 CH131) MTWR 9:00-10:35 am, Room SC-462 (Science Center). Discussion Sections (10463 CH 131D): MW 10:45-11:50 am Room SC-305 (Science Center). Office Hours: MW :40 am, Room SC-331-M (Science Center) ph: Prof. William A. Boyle PhD; Concepts of atomic structure, chemical bonding, periodic table, nomenclature, stoichiometry, solutions, thermochemistry, mass relationships, kinetic-molecular theory, gases, liquids and solids, and solutions will be covered. Properties of the elements with emphasis on atomic structure and the periodic table will also be covered. Prerequisites: MA097 or MA099 or equivalent; completion within the past few years with a grade of C or better for CH099A or a passing grade on the chemistry placement exam, or consent of the department. You also need to have knowledge of basic math and algebra skills. COURSE AND GRADING POLICY 1. Text, material covered: The text for this course is "Chemistry, A Molecular Approach" by Tro, 2nd or 3rd edition (2010). Material to be covered and for which students are responsible is given in the Course Outline. 2. Classes. Regular and prompt attendance of lectures and discussion sections is essential to an understanding of the subject material. You should be prepared for each class in the following manner: a. Have read the chapter material which will be covered in the lecture. b. Have completed, or at least made a serious attempt to complete, the assigned homework. c. Have with you notebook paper and hard copies of PowerPoint presentations (recommended). d. While in class please ask questions at any time. Chances are if you have a question concerning the lecture material, then somebody else probably has the same question. e. If you miss a lecture, you are still responsible for the material covered. 3. Homework. It is essential that you do the assigned homework problems, at a minimum (see on-line homework instructions). Note the deadlines for each chapter homework!!! This is not a History course; you cannot learn the material solely by reading the textbook. Working problems and answering questions is the only way to fully understand Chemistry, and it is essential that you try to work as many of the assigned problems as an aid to understanding the material. The only way to learn problem solving is to solve the problems. It is also suggested that you find other people to work with, i.e., form study groups, to get different viewpoints in solving problems, although a serious individual effort should also be made to solving problems. Homework problem assignments will be graded. Late assignments can still be performed but will not receive credit. 4. Calculators. Calculators are usually needed for laboratory, homework and examinations. A scientific calculator is recommended. However, programmable calculators or any kind of wireless devices (cellphones, tablets, etc.) are not allowed during examinations of any kind. The calculator should have the ability to perform log and antilog functions in CHEM132. If you have a question concerning the use of your calculator, please ask. Students may not exchange or loan calculators during any exam or quiz. 5. Laboratory. The experiments are to be read before coming to lab. Failure to read the lab could result in your being considered a safety hazard. Safety regulations for work in the laboratory will be enforced; in particular, safety goggles will be worn at all times while in lab. In addition, open toe shoes are not allowed and long hair should be tied back. Further details on safety guidelines are given in the CHEM 131 Laboratory Blackboard website and are to be observed. Specific details concerning lab report requirements, lab quizzes, etc. will be provided in your laboratory section. Your laboratory instructor will provide more information. At the end of the semester, the laboratory grade accounts for 25% of the total course grade. NOTE: You must independently pass both the lecture and the lab to get credit for the course.
2 6. Extra Instruction. If you have questions concerning the course material outside of lecture, then please come and see me. My office is Room SC 331M. In addition, the chemistry study center (Room SC 315) is stocked with a collection of general chemistry texts and workbooks. There is also general chemistry help available from 11:00 am to 12:00 noon, M, W, Th, F (no Tu) in Room SC-302. The Math/Science center should have a tutoring schedule available. Please see them for additional information on days and hours that tutors are available, Math/Science center policies, etc. Again, do not hesitate to come and see me if you have questions. Office Hours: MW :40 am,, or by appointment. Office Location: SC-331M ( Science Center). 7. Grading Policy. a. The following grading system will be followed during this semester: A % D 69-60% B 89-80% F 59% and below C 79-70% This should be used as an initial guide to grades. Final grades may be determined based on a distribution curve. b. Grading will be based on the following outline. 3 1 hour 100 points each 300 points 3 quizzes (best 5 of 6 will be 25 each 75 1 comprehensive final exam 250 Laboratory 250 on-line homework 100 attendance/participation/extra-credit 25 Total 1000 points 8. Examinations. There will be three (3) hour examinations scheduled and a cumulative final exam. If you are unable to take an exam at the scheduled time, see me in advance to make arrangements for taking it at an earlier time. In emergency situations where advance notification is not possible, contact me via no later than 8:00 am, the day of the exam. If an exam is missed due to a valid reason as defined by the college (illness, etc.), then see me to discuss possible options. MISSING OF AN EXAM WITHOUT NOTIFYING ME AS ABOVE WILL RESULT IN A ZERO FOR THE EXAM. NOTE: NO MORE THAN ONE MAKE UP EXAM, WITH VALID EXCUSED ABSENCE WILL BE PERMITTED. Note: All activities in this class are governed by the Student Code of Conduct printed in the Student Handbook. Violations, such as plagiarism, cheating, etc., will result in a loss of points, a grade of F for the work, etc. in accordance with the Student Handbook. If you have any questions about what is and is not allowed, please ask. During class, please make sure that cell phones, etc. are turned off to avoid disrupting class and the other students. 9. Students with disabilities Any student who may need an accommodation due to a disability, please make an appointment to see me during my office hours. In order to receive accommodations, a letter from Disability Support Services (R-CB122, G-SA175, or TP/SS-ST120) will be needed. Any student who may need assistance in the event of an emergency evacuation must identify to the Disability Support Services Office; guidelines for emergency evacuations are at: 10. How to contact me: If you can t see me during class periods, the best way to contact me is via at In the event of an emergency that requires the building (Science Center) to be evacuated, students are to leave the building in an orderly manner and proceed to the parking lot (Lot 11) near the Counseling and Advising building. We will wait there until the building is reopened, or we receive further instructions.
3 If you are a veteran or on active reserve status and you are interested in information regarding opportunities, programs and/or services, please visit the Combat2College website at and/or contact Joanna Starling at or CHEM 131 fulfills a General Education Program Natural Science with Laboratory Distribution requirement. Montgomery College s General Education Program is designed to ensure that students have the skills, knowledge and attitudes to carry them successfully through their work and personal lives. This course provides multiple opportunities to develop the following competencies: written and oral communication, scientific and quantitative reasoning, and critical analysis and reasoning. For more information, please see What Do You Need to Do to Be Successful in this Chemistry Class? Attend (in mind and body) all class sessions. Arrive on time and stay for the whole time. Experience shows that you will not be successful if you are not present. Read and use your syllabus packet. Not only does this provide the lab/discussion schedule but it also provides knowledge and process goals, and textbook problem assignments. Read the material in the textbook as it is covered in class. Do the assigned questions at the end of each chapter as we finish the section. Don t wait until the end of the chapter or the night before the quiz or exam. This is an excellent way of assessing your understanding of the concepts we have been covering. The labs you will be doing are inquiry-based. That means you are investigating, testing, challenging ideas, and learning rather than just following directions to verify something you already know. Read the lab activity before coming to lab class so that you will be oriented to the task. Do any pre-lab questions before getting to lab. Complete all assignments on time. Points are deducted for late assignments. ASK if you have a question. Don t wait for revelation... The sooner you address a problem, the easier it is to solve. Out-of-class STUDYING time is at least twice the amount of in-class time! So figure on about 3 to 6 hours of out-of-class work each day. Study and review notes and/or handouts as soon as possible after class. Work with classmates to help clarify your thought processes and as practice. Forming a study group is highly recommended. During exams, cell-phone calculators or wireless devices are not allowed, and calculators may not be passed to another person, and you may not leave the room. If you leave, your exam is over.
