Otherwise, missed work = zero points! Grading: Exams 400 points Scale: A 90-100% Final 200 points B 80-89% Daily Quizzes 100 points C 70-79% Laboratory 200 points D 60-69% Homework 50 points (not in total) F 0-59% Total 900 points Final: The final examination is worth 200 points and is cumulative. You must take the final examination to receive credit for the class. The final exam will be given on Tuesday, December 16 th 2008 from 7-9 pm. 1
Daily Quizzes: There will be daily quizzes given in the first 5 minutes of lecture worth 5 points each. The daily quizzes will be worth a total of 100 points towards your score. There will absolutely be no make up on any of the daily quizzes once given. So, it is your responsibility to be on time for each lecture. The 2 lowest quiz scores will be dropped throughout this semester. Laboratory: You must be enrolled in a laboratory concurrently with the corresponding lecture. In order to pass the class, you must complete all laboratory assignments with a satisfactory score. Failure to pass the laboratory with a C or better will result in an F for the class. Bring safety glasses/goggles and closed toed shoes to every lab section. Please use your cell phones outside of the lab if it is an emergency. Homework: 10 homework assignments will be collected during the semester. Each homework assignment is worth 5 points and will be added to your overall score to help you out. Homework assignments will be assigned approximately every week and a half. You will have one week to complete the homework assignments once assigned. Solutions to the homework will be either handed out or posted after the due date of each assignment. Late homework will not be accepted at all! Course Objective for CHEM051: This course is a 5-unit introductory level chemistry course. The topics covered will include the following: basic scientific principles, measurements and units, atomic structure and reactivity, state of matter, basic organic chemistry, functional groups, basic biochemistry, carbohydrates, lipids, proteins, and molecular genetics. This course will develop problem solving skills and basic data analysis. By the end of the course you should be able to: 1. use the language of general chemistry (vocabulary, nomenclature, formulas and equations) to describe chemical systems and changes (physical and chemical) they undergo. 2. describe the structure of the atom in terms of the arrangement of subatomic particles and electronic configuration. 3. extract information from the Periodic Table and predict periodic trends. 4. distinguish between ionic and covalent bonding and write Lewis structures for molecules and polyatomic ions. 5. predict molecular geometry, bond angles and polarity. 6. solve introductory level quantitative problems applied to chemical systems by using dimensional analysis and algebra. These problems include unit conversions, stoichiometry, gas laws, solution concentrations and ph. 7. describe the properties of solids, liquids, gases and solutions and relate them to bonding and intermolecular forces. 2
8. discuss the factors which affect the rate of reactions and how energy is a key role for all chemical reactions in chemistry. 9. state the properties and definitions of acids and bases and interpret elementary acid-base equilibria, including buffer systems. 10. describe the bonding and geometry of carbon compounds in terms of hybridization and type of bonding orbital overlap (pi or sigma). 11. use mechanisms to show how selected organic reactions take place. 12. determine the nomenclature and write equations for the preparation and important reactions of alkanes, alkenes, alkynes, alcohols, thiols, and ethers. 13. state the names of common aromatic compounds and describe the structures of these compounds. 14. recognize a chiral center in an organic compound. 15. use common laboratory glassware and equipment. 16. state and apply the rules and procedures for laboratory safety. 17. demonstrate the ability to use basic laboratory skills such as taking and recording observations of chemical systems and interpreting qualitative and quantitative experimental data.

Course Material: The course materials for this section will be available online. The lecture notes are all Powerpoint presentations which you will be able to download from either moddle link: http://online.lasc.edu/ or my own personal webpage at http://chemistry.csudh.edu/faculty/krodriguez/ken.htm. Homework assignments and any other materials will also be available for you to download. Academic Misconduct: Cheating and/or plagiarism will result in an F grade for the course. Dishonest students will be reported to the administration for further disciplinary action. No programmable calculators or devices with alphanumeric text storage capacity will be allowed in the exams (including language translators and cell phones). Communicating with another student during the exam will result in a zero. Attendance Policy: It is the responsibility of the student to attend lectures and labs. Failure to attend lectures may result in zeros on homework and exams due on those days. Be PROMPT and regular in attendance. Quizzes and Tests are lecture-based and may include questions on material covered only in Lecture (i.e. not discussed in the texts). Consistent late arrival may result in a lower grade; MORE THAN FOUR ABSENCES may result in being dropped from the class. Attendance points will be given for the lab. Failure to report to lab will result in no credit for the assignment. If you arrive to LAB after discussion of safety procedures you may be excluded from the lab (0 pts) that day. A 10-min break will be given midway through lab. Classroom Etiquette: Please arrive to lectures and labs on time. Turn off all cell phones and pagers when in class! Points may be deducted for such interruptions - is that incoming call worth it? Be respectful of others. Do not bring visitors to the class or laboratory. Extra Credit: There are no extra credit assignments. There is plenty of non-extra credit work to complete. For chemistry practice problems online that will help you out for this course, please visit http://proton.csudh.edu/homeworkcs/hwintrocsn7.html. Bonus problems may be given on the exams for extra credit. Re-grading Policy: No re-grades unless there is a clear error in the adding of points. 7
