CHEM 30A INTRO CHEMISTRY SPR 2014 Instructor: Nisha Guha; Email: nisha_guha@yahoo.com Office Hrs: T/Th 10:50 11:50 am: Rm A236A (office) Lecture T/Th 8:00-9:15 am Lab T/Th 9:30-10:45 am Course description: Chem 30A is an introductory chemistry course designed for nursing and allied-health majors. Topics include dimensional analysis, inorganic nomenclature, atomic and molecular structure, bonding, chemical reactions, gas laws, solutions, acid-bases, oxidation-reduction, equilibrium and electrolyte systems. No prior knowledge of chemistry is assumed. Required textbooks and tools: "Fundamentals of General, Organic, and Biological Chemistry" by McMurry, John E.; Hoeger, Carl A.; Peterson, Virginia E.; Ballantine, David S. 7th edition. ISBN 9780321750839. NOTE: Chem 30A will be covering only the first 11 chapters of McMurry Chem 30A Laboratory Manual, Laney IMC. Available online at my website: Scientific Calculator (eg, TI30X): must have exponential, log, and square root. No programmable calculators, and no online devices during testing. Recommended: If your math needs help: Problem solving books such as Leo Michel s Basic Math for Chemistry, or the Schaum outline series (both at bookstore and online). Prerequisite, etc: College English: for ESL, this corresponds to the 200 and 240ESL series Math 201 or 210D or Math 208 Student Learning Outcomes: Upon completion of the course, the student will: 1. Use dimensional analysis to solve quantitative problems and evaluate the results of calculations to make sure they are physically reasonable. 2. Clearly explain qualitative chemical concepts and trends. 3. Describe, explain, and model chemical and physical processes at the molecular level in order to explain macroscopic properties. 4. Perform laboratory techniques correctly using appropriate safety procedures. 5. Calculate experimental values from laboratory data and interpret the results. Course Structure: Basis of Evaluation A. Lecture There will be 2 midterm exam and one Final exam (comprehensive) and 3 Quizzes (may be 4), each covering the materials specified in lecture schedule. Test questions will include materials and topics covered in class room Lectures and Practice-Questions assignments. The format for quizzes and exam shall be same and will consist of multiple-choice questions, short answers, explanatory answers and problems. For problems-based questions,
all supporting calculations and explanations that lead to the answer must be shown to receive full credit. Programmable calculators with a letter keyboard for storing text materials are not permitted during the exam. Practice Questions (PQ) PQ assignment are assigned in class and are for students to practice for quizzes and exams. These questions should be considered as key towards Quizzes and Midterm exams. Completing the PQ assignment in a timely manner will be beneficial toward getting a good grade for the course. Questions that require problem-solving must show all calculations leading to the answers. Exams: There will be two Midterm exams and one Final Exam given check syllabus for tentative exam dates. NO MAKE-UP FOR QUIZZES/EXAMS, and I do not drop any exam grades. No more than one missed exam will be permitted. Math problems on the math portion of the exams/quizzes must show all work. Exam Questions will involve manipulating chemical symbols, calculating numbers, drawing pictures and graphs, making predictions, and offering well-written explanations for conceptual questions. You are expected to know key words for the exam. You will not be allowed to use any electronic devices (calculators excluded), a dictionary, or a translator during an exam. Also, you cannot have cell phones, or blue tooth devises visible during the exam. They should be in your book bag. No extra time will be allotted for lateness. Policy on Electronic Devices: No electronic equipment (this includes games, electronic translators, cell phones (This a blue tooth device, too. Take it out of your ear before you come to class.), TV s, radios) will be allowed in lecture or in lab. It is a safety issue in lab. If you are listening to music, you will not be alert to the dangers around you. In lecture, having a CD playing while you listen to lecture is a distraction to other students. Turn your cell phones, pagers, and any other electronic entertainment off during lectures and tests, unless I say it is okay to use it. I will confiscate the equipment if you cannot manage to comply. If someone is annoying you with music or other reasons, you need to alert me immediately. The final exam is comprehensive Missing the final exam will constitute course failure. Don t miss it! DO NOT ASK ME TO GO OVER MATERIAL THAT YOU MISSED BECAUSE YOU ARE LATE THAT IS YOUR CHOICE NOT MINE. Labs: Lab reports are due at the end of each lab no exceptions unless granted by me. A maximum of two labs can be missed; missing three laboratories constitutes failure in this class. Reports will be graded on legibility/neatness, completeness, and correctness show all math work. NO MAKE-UP LABS. A lab report cannot be turned in for a lab you missed. Note that we will work in pairs in the lab, but each student is expected to carry their own weight, and will be graded accordingly. Student responsibilities: It is the student s responsibility to add and drop the class. It is the student s responsibility to keep copies of all graded exams, labs, homework. Note that the lecture is not intended to be exhaustive. Lecture will cover selected chemical concepts and math problems from the text in order to help the student access (understand) the material assigned in McMurry. On exams, etc., the student will be held responsible for all the material assigned in the McMurry text and content covered in lectures.
Class Participation: Attendance will be taken during each lecture and lab. Lecture attendance will be taken during each class only once! The lab report, handed in at the end of lab, will usually constitute lab attendance. A lab report cannot be turned in for a lab you missed. Grading: The overall course grade will be based on total points. The final grade will be made up of the following contributions. The final is comprehensive! Lab reports = 150 pts (@ 10 point each) 3 Quizzes = 75 pts Practice Questions = 80 (may get added @20 point each) Midterm 1 = 100 pts Midterm 2 = 100 pts Final = 150 pts 880 pts Grading scale: A 90%; B 80%; C 65%, and D 55% I don t grade on curve! Academic Honesty Policy: Students are expected to perform honestly and ethically in completing homework and class assignments. Behaviors that are dishonest and unethical include plagiarism, cheating, fabrication, aiding and abetting dishonesty, and forgery, alteration, or misuse. Students found cheating will receive an F on the activity, and may be referred to the Dean of Instruction. Student Code of Conduct: The Student Code of Conduct is guided by the California Education Code. The Peralta District upholds expectations regarding student standards of behavior, both academic and non-academic, which may result in disciplinary actions. Rehabilitation Act: The Rehabilitation Act of 1973, Section 504, requires Laney College to make all programs accessible to qualified individuals with learning, physical, or psychological disabilities. Any student who feels s/he may need an accommodation based on a disability should contact me privately to discuss your specific needs. Early withdrawal from class Please consult with me before deciding to withdraw from the class. If after discussing the situation, the decision is made to early-withdraw, it is the student's responsibility to submit a drop slip to the admissions office. Students who fail to do so will receive an F grade in the class.
