Laboratory experiment Chem 60/68) COURSE DESCRIPTION A general basic chemistry course with laboratory and conference, emphasizing fundamental principles of inorganic and physical chemistry, nomenclature of inorganic compounds, ionic and covalent bonding, problem solving, gas laws and solutions. This course serves as preparation for Chemistry 101, and satisfies the IGETC and CSU general education requirements for physical science with laboratory.

Math 115 or appropriate score on placement assessment. Advisory: Eligibility for English 28/31. REQUIRED MATERIALS AND FEES
The following materials/items are required for the entire duration of the course and must be obtained no later than the second class meeting. 1. The textbook and laboratory manual (see required texts) 2. Scientific calculator – it need not be “fancy”, but must be able to perform multiplication, division, and addition, subtraction, square root, exponential, and log functions. Have your calculator with you at all times during lectures, laboratory sessions and examinations. 3. Safety Goggles – goggles must be worn during all laboratory work and can be kept in your laboratory lockers. Goggles can be obtained at LACC bookstore. Any experiment cannot be performed without wearing goggles, unless stated otherwise by the instructor. 4. Periodic Table of Elements – this can be obtained at the bookstore and must have one with you at all class/lab sessions.



COURSE EVALUATION Latter grade will be assigned only at the end of the semester, and the final grade is composed of the following: Quizzes 150 points EXAMS (three, 1 hr each) 300 points Final EXAM 200 points Lab Reports/Workshops 200 points OWL (online based homework) 150 points TOTAL 1000 Points GRADING SCALE The final grade is determined as follows: 90% -100% A 55%- 64% D 80% - 89% B Below 55% F 65%- 79% C GENERAL POLICIES 1. No make up exams or quizzes will be given under any circumstance. 2. Attendance to lectures and labs is mandatory (chemistry is a demanding subject!). Coming prepared to the lecture and lab sections is important. It will help you comprehend the topic better and ask key questions during lectures. 3. There are ~15 experiments and about 25 laboratory sessions. Lab reports are due one week after completion of an experiment (no exceptions!). Lab reports to be discussed in detail at the first lab session. 4. Avoid disruptive behavior during lectures as a simple courtesy to others. LACC guidelines apply to disruptive students including oral warnings, written warnings and suspension. 5. NO cheating! Cheating guarantees an automatic zero on the particular assignment or exam to be followed by further disciplinary actions. 6. Final exam is MANDATORY and failure to take the final will result in an automatic fail in this course, regardless of your grade prior to the final. FINAL EXAM WILL BE HELD WED, DEC 16, 7:30PM -9:30PM PER SCHOOL POLICY. LABORATORY WORK AND WORKSHOP POLICIES  The laboratory locker and contents will be assigned to each student during the check-in session. You will be solely responsible for drawer contents.  You will be performing the experiments in the order listed on the schedule. Experiments will be done individually unless instructed otherwise. Each student must submit his/her own laboratory report.  You must print out the procedures or workshops prior to arrival for your lab sessions. Computers are available on campus for your use (library, chem. Dept etc).



 No report or workshop cannot be accepted if you are absent on the day of an experiment/workshop. Talk to your laboratory instructor in advance, if you have a pressing issue and cannot come to lab session.  ALL workshops are to be completed and turned in at the end of the lab session on workshop only days. Seek help from your lab INSTR and feel free to use the entire lab session to complete exercises.  Each workshop is worth 15 points and lab reports are worth 20 points. The final score will be normalized to a total of 200pts (see course evaluation above).  Each student must have an appropriate laboratory notebook. Use a bound (not a spiral or loose-leaf) notebook with numbered pages for keeping laboratory data. Lab notebooks can be obtained at the bookstore.  A written record of what you are doing in the lab will be kept in your notebook. You are expected to have your notebook with you in the lab. Failure to do so can affect your grade. The notebook entries will be written in ink. The carbon copies that you make will be submitted with your lab reports.  All primary data should be directly recorded into your notebook to avoid transmission errors. Avoid the use of scratch sheets. Data for weighing should include a tare weight, a gross weight, and the sample weight (by difference). Never record only the sample weight.  Lab notebook format; must have the following sections. 1. Title and date of the experiment 2. Objective. State the goal of the experiment here. 3. Procedure. You can refer to your printed-out procedures here. 4. Data/observation 5. Results/calculation 6. Conclusion. State the purpose and goal of the experiment, whether you achieved your goals or not and any experimental errors you are aware of in this section.  Come prepared to the lab session by reading the introduction/procedures at least twice. This will allow you finish experiments within the allotted time. NOTE THAT COMPLETION OF ALL LABORATORY WORK IS REQUIRED IN ORDER TO RECEIVE A GRADE FOR THE CLASS. Information for Students with Disabilities: Students with a verified disability who may need a reasonable accommodation(s) for this class are encouraged to notify the instructor and contact the Office of Special Services (CH 109, (323)953-4000, Ext. 2270) as soon as possible. All information will remain confidential. Expected Student Learning outcomes: Upon successful completion of chemistry 60, the student will be able to demonstrate competence in the course approved student learning outcome: Students will solve a stoichiometry problem in which the limiting reactant is known.
