“The greater danger for most of us lies not in setting our aim too high and falling short; but in setting our aim too low, and achieving our mark." Michelangelo, Italian sculptor, painter, architect and poet, (1475-1564)

Chemistry 141 is the first semester of the one-year general chemistry course (141-142). It is assumed that you have had a previous course in chemistry and can do problems in stoichiometry, solution concentrations, gas laws and that you can name common inorganic compounds and write their formulas. Also that you are familiar with basic laboratory equipment such as balances, burettes, pipettes, graduated cylinders, etc. Most of the first two or three weeks of the course will be spent reviewing basic material, material you should have covered thoroughly in a previous course. Following this, new topics will be introduced. The course consists of three hours of lecture instruction and six hours of laboratory per week. Attendance at these sessions is required. Plan to spend at least two hours per lecture hour and one hour per lab hour per week additional study time.

1)Solve stoichiometry problems involving mass, moles, mixtures, gas volumes, and limiting reactants.

2)Solve gas problems using the ideal gas, combined gas, Dalton's partial pressure, and Graham's effusion laws.

3) Demonstrate proficiency in chemical nomenclature.

4) Identify and balance net ionic equations for oxidation reduction, acid base and precipitation reactions.

5) Demonstrate quantitative and qualitative understanding of chemical equilibrium,

6) Demonstrate understanding of chemical periodicity in terms of quantum mechanics and atomic structure.

7)Analyze the bonding in chemical compounds in terms of Lewis structures, VSEPR, valence bond theory, molecular orbital theory

8) Calculate enthalpies of reactions using Hess' law, bond energies, and calorimetry.

9)Apply the first and second laws of thermodynamics to chemical systems

10)Solve colligative property problems and explain solution properties in terms of vapor pressure and intermolecular interactions.

11)Demonstrate ability to analyze a phase diagram.

12)Apply science methodology in a laboratory setting.

13)Demonstrate proficiency in quantitative chemical analysis techniques.

14)Apply kinetic molecular theory to describe the properties of solids, liquids and gases.

15)Demonstrate correct documentation of experimental data in laboratory notebook and presentation of analysis in a formal lab report.

16) Solve problems involving the relationship of pH, pOH, and Kw in aqueous solution.

Prerequisites: Grade of “C” or better in Chemistry 120 at Grossmont, the equivalent or successful completion of the Chemistry 141 entrance exam. A working knowledge of intermediate algebra is mandatory. This includes such topics as solving simultaneous equations, graphing of various functions and the algebra of logarithms.

A pen with nonerasable ink is required for the recording of all laboratory data.

Lock for laboratory drawer - Must be Master Lock, series recommended by stockroom.

Additional requirements: Calculator -- A standard nonprogrammable scientific calculator is required for the course.

General Guidelines – Registration should be completed before checking into lab. If registered late, bring your validated receipt to lab. You will be charged for all breakage or loss of laboratory equipment, in addition you will be assessed a $10 fee if you fail to check out of the laboratory before the end of the semester.

Regular attendance is expected. (A roll sheet may be passed at each class.) The instructor will plan to drop any student who misses over 3 classes. (BUT this is not a guarantee!) If you wish to drop, you should turn in the forms and get a receipt.

Those enrolled at the end of the semester must receive a letter grade unless they have chosen the CR/NC option. An “incomplete” may be arranged for completion of a particular item such as the final exam, but will not be given to allow a repeat of the course. Withdrawal or CR/NC grading is available through admissions and records.

Chemistry 141T, the computer drill course, is recommended. There is a free tutoring service in the library building, and chemistry instructors are available to all students during “open” help times.

Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and contact Disabled Student Programs & Services (DSPS) early in the semester so that reasonable accommodations may be implemented as soon as possible. Students may contact DSP&S in person in Room 110 or by telephone at (619) 644-7112 or (619) 644-7119 (TTY for deaf).

ipods, mp3 players, cell phones…or the like will not be allowed during lecture or lab! Turn these items off and put them away before class begins.

Approximately 88% will be an A, 78% a B, 67% a C and 55% a D grade. Please note however that anyone with less than a 50% average on the exams (including final), or on the labs will receive an F All grades may be subject to a ( +/-) 1-2 % instructor evaluation of the student. (Evaluation may be based on homework, class participation, etc.)

Quizzes -- Quizzes will be given in lab. There will be 9 - 12 quizzes given over the course of the semester and 1 or 2 will be dropped. Material from both laboratory and lecture may be included. Much of the material on the quizzes will be similar to the material found in the assignments. No makeups are given for missed quizzes. Missed quizzes will count zero points and will be counted as low scores when dropping quizzes.

Exams -- Exams will be given in the lab as noted in the schedule. Please do not miss these examinations. If you know that you cannot be present for an exam, you must arrange for a make-up with the instructor in advance of the scheduled time. Please note that make-up exams may not be the same exam given to the rest of the class and may be more difficult than the regularly scheduled exam.

Assignments -- These include computer exercises and homework. Computer exercises – These are computer graded homework that are available via www.masteringchemistry.com Instructions for accessing these tutorials may be found at the end of this document. Homework assignments - Problems and questions from the textbook are assigned on the syllabus.

Laboratory Work – There will be a short lab quiz prior to the start of a new lab and will be part of your lab score. These quizzes ensure that the lab was read prior to your scheduled lab time. They will be worth 10 points each. Your laboratory work must be done and completed during your regularly scheduled time and the reports must be turned in to pass the course. Lab reports are due one week after the period in which they are scheduled to be completed. The format for writing up lab reports is appended to the end of this document.

Deductions will be made from the overall laboratory grade for failure to follow basic laboratory protocols as outlined below:
Always wear eye protection (without reminders from the instructor) Wear appropriate clothing- closed-toe shoes, long pants, no sleeveless tops, no dangling jewelry or neckties etc. Tie back long hair Use proper technique when handling glassware (we will review new techniques) Properly clean up any minor chemical spills; report major spills to the instructor Clean up your hood space and put away your equipment at the end of lab, turn off gas, and lock your locker (no lock after 1st week will result in point deductions on labs

Additional Information The faculty and the college have determined that integrity and honesty are essential to the academic process and that it is necessary that the written materials submitted by each student in a class reflect his or her own work for that class.

Submitting work as one’s own which has been done either all or part by another is defined as CHEATING.

“CHEATING” includes but is not limited to the following: The possession or use of unauthorized materials such as crib notes or unauthorized copies of exam material. Copying from another person’s quiz or exam or allowing another person to copy one’s examination material. Copying another person’s lab data or report and turning it in as one’s own or allowing another person to copy one’s data.

Using a calculator or computer which contains stored information that can be used while taking a quiz or exam. The possession and/or use at the students work area of a personal communications device during exams or quizzes. Submitting a false report for work that was not actually done. Modifying or attempting to modify an answer on an exam after it has been returned and then claiming it was graded incorrectly.

We hope that each student will support this policy and realize the importance of honesty and integrity in his or her academic effort!

Cheating can result in any one of a variety of sanctions. Such penalties may range from an adjusted grade on the particular exam, paper, project, or assignment to a failing grade in the course. The instructor may also summarily suspend the student for the class meeting when the infraction occurs, as well as the following class meetings. For further clarification and information on these issues, please consult with your instructor or contact the office of the Assistant Dean of Student Affairs.

Accommodations for Students with Disabilities: Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and contact Disabled Student Services & Programs (DSP&S) early in the semester so that reasonable accommodations may be implemented as soon as possible. Students may contact DSP&S in person in room 110 or by phone at (619) 644-7112 (voice) or (619) 644-7119 (TTY for deaf).

Additional Chemistry Assistance
There is a free tutoring service in the library building, and chemistry instructors are available to all students during "open" help times. Chemistry 141T, the computer drill course, is recommended.

Suggestions for Success
It is not a secret that Chemistry can be a difficult course. Let me make a few suggestions for success. First, do the homework. Do all the homework, and do it thoroughly. If there are problems you cannot get, be sure to come to me for help or to ask a question in class.

The second suggestion is to form an informal study group. This would be a group of two, three or four students who meet regularly to work homework, study for quizzes and tests and share work toward writing up labs. It is the experience of this instructor that this is the best setting for learning to go on, as the stronger students teach the weaker and all benefit. Tutoring and 141-T are excellent resources, but your study group is the most valuable of all.

Third, I will be giving you problem sessions before each formal exam. However, the exams will not be exactly in the from of the problem session. The problem sessions are to help you prepare for the exam along with homework, lecture material and lab material.

Last, if at any point you are getting lost or significantly behind, please come see me for help. Helping students is what I am here to do, and it also happens to be what I love to do, so please come for help if at any time you are in need.
