Course Description:

Fundamental chemical principles; the components of matter; quantitative chemical analysis and stoichiometry; chemical reaction types and solution chemistry; gas laws; thermochemistry; quantum theory; electron configurations; chemical bonding models. The lab is an introduction to the basic methods of chemical experimentation with a strong emphasis on quantitative chemistry.

Required Materials:

  1. Brown, LeMay and Bursten, Chemistry: The Central Science 11th ed., Prentice Hall (Includes Media Package Option 1, Math Review Toolkit, Student Lecture Notebook and Student’s Guide). Available at the bookstore. To be used for three quarters.
  2. Laboratory Packet of Experiments and Exercises for Chemistry 1A. Available Online Only www. Foothill.edu/psme/daley
  3. Scientific Calculator.
  4. SAFETY GLASSES or GOGGLES are REQUIRED in LAB at ALL TIMES! Available at the bookstore.

Optional Materials:

  1. Roxy Wilson, Chemistry: The Central Science Solutions to Red Exercises., Prentice Hall. Available at the bookstore.
  2. Old clothes for lab.

Grading:

Grading will be based upon two midterm exams, a comprehensive final, and laboratory work. When computing course grades, each student’s overall percentage will be determined from the following:

Two Exams 40% (20% fro each midterm)

Lab 30%

Final Exam 25%

Letter grades will be assigned on a percentage scale:
A: ≥ 90 % A–: ≥ 88 %B+: ≥ 84 %B: ≥ 80 %B–: ≥ 75%
C+: ≥ 70%C: ≥ 65 %D+: ≥ 61 %D: ≥ 55 %D–: ≥ 52 %

Plus/minus grades will be assigned as part of a study at Foothill to determine the impact of +/– grading on student GPA's.

If you fail the either the lecture or laboratory section of the course you cannot receive a passing grade.

Since there is a prerequisite for this course, I expect you to already be familiar with some of the material. For example, you should be familiar with most of the following topics:

  • Chapter 1-Elements, compounds, mixtures, physical and chemical properties, physical and chemical changes, units of measurement, the metric system, significant figures and unit conversions.
  • Chapter 2-Basic atomic structure and theory, the nuclear atom, atomic number, isotopes, the periodic table, ions (cations and anions) and naming inorganic compounds.
  • Chapter 3-Balancing chemical equations, the mole (Avogadro’s number), molar mass, converting between moles and grams.
  • Chapter 4-Acids and bases, solution concentration (molarity) and dilution.

Although only limited lecture time will be spent to review this material, you will be tested on it.

Lecture Exam Dates

Two exams will be given during the quarter:
Th., Oct 22 (5th week) and Th. Nov 19 (9th week).
Final exam:
“Tuesday, Dec 08 10:00am
YOU WILL BE REQUIRED TO BRING A PICTURE ID TO ALL EXAMS, INCLUDING LAB EXAMS.

Make-up Exams

Make-up exams will NOT be given.

Academic Dishonesty

Any form of academic dishonesty will be grounds for dismissal from the course. FoothillCollege has information regarding academic dishonesty in the schedule of classes. Please read it! Violations will be reported.

  • Plagiarism on lab exercises and reports constitutes academic dishonesty.
  • During an exam, communicating or transferring information to another student, receiving information from someone else, looking at another person’s exam, and/or using unauthorized materials such as text books, notes, etc. are prohibited.

Class Rules and Regulations-Repeated disruptive or rude behavior will be cause for dismissal from the class.

  1. Arrive on time and be polite to your instructor and fellow students.
  2. Talking to fellow students during lecture is disruptive. Remain quiet during lecture. Raise your hand if you have a comment or question.
  3. Turn off or turn to silent mode all cell phones and pagers while in lecture. DO NOT talk on the phone during lecture. If you receive an urgent call or message, quietly leave the classroom to respond to it.
  4. Clean up your lab bench after lab is complete.
  5. Follow all written and VERBAL instructions.

A few of the items that you must memorize for this course: (There will be more added to this list as the quarter progresses.)

The following units:mass: gram, glength: meter, mtime: second, svolume: liter, ldensity: g/mL1 ml = 1 cm3Solubility rules for ionic compounds.Names of selected polyatomic ions. A list will be provided.STP for gases: 0°C and 1 atmHess’ Law: ∆H˚rxn = ∑n∆H˚f (products) – ∑m∆H˚f (reactants)Standard states for thermochemistry: 1 atm for gases, 1M for aqueous solutions, most stable form for pure substances.

FAQ-How do I get a good grade in general chemistry? Realize that you are responsible, through your own hard work and efforts, for your success. NO EXCUSES! My role as your instructor is to be your guide, to offer insights into the material and to help when you are having difficulties. I cannot learn the material for you. Set high personal goals for lab work and examinations and focus on learning, not just the grade. The following offers some more detailed suggestions:

Develop good study habits. To be successful in General Chemistry you must have good study habits. For ANY CLASS, the recommended study time is AT LEAST 2 hours outside time per hour of lecture. Including regular lecture and lab lecture, we have 5 hours of lecture per week in General Chemistry. This means that you should study outside of class AT LEAST 10 hours per week. This is for every week of the quarter, not just the week or weekend before an exam. Cramming does not generally work for chemistry! Be sure to make the study time count by removing distractions-for instance, do not watch television or carry on conversations while studying. Also, make sure that you are well rested and eat healthy so that your brain can function at its best! Studies have shown that a person’s I.Q. temporarily declines when they are sleep deprived.

  • Read the textbook regularly and carefully. Do not be surprised or alarmed if you must read the material two or three times to gain a full understanding of it. This is normal for a chemistry class! In fact, you should read the sections in the textbook to be covered in lecture BEFOREHAND! This will make it much easier for you to follow the lecture and take good notes.
  • Come to lecture prepared to learn. Prepare by reading the textbook ahead of time and coming to lecture alert and ready to learn. Bring a pencil or pen, paper and your calculator.
  • When you need help, come to office hours prepared. Keep a list of questions to bring when you come in for help. Bring a pencil or pen, paper and your calculator. If you have trouble solving a homework problem, bring the work you have done on it so far.
  • The night before exams should be spent reviewing what you have already learned. Pulling an “all nighter” (or cramming) just before an exam will result in work that is not to the best of your ability. This type of studying can also result in a lack of confidence and extreme nerves during the exam.

Do the suggested homework problems. A major key to a good grade in chemistry is to practice problem solving. This tests you on your knowledge and prepares you for exams. The problems at the back of each chapter are designed for this purpose. If you cannot do the problems in the back of each chapter in a reasonable amount of time without referring to the text or solutions manual, you may not pass the course. For assigned problems that do not have answers in the back of the text, see the instructor to check your work. In addition to the assigned problems from the text, there are eMedia Exercises at the back of each chapter that make use of the Companion Website. These are not assigned, but you can use them to further test your knowledge of the material and some of them are fun!

Resources

Mr. Jimmy Li-See me regularly during office hours for help. Do not wait until the week or day of a test!

  • Other Students

Help each other to learn (not copy!)

Lab is a great time to get help

  • Tutoring Center: See the website for hours and location.
  • Textbook

The companion website at has chapter summaries, practice questions, an eMedia Library, a math tutorial and more!

“Give it Some Thought” questions within each chapter are excellent!

Check your knowledge of the material by doing the assigned homework!

  • Copies of the textbook and solutions to the red exercises will be on reserve at the library.
  • Videos on reserve at the MEDIA CENTER

The videos are subtitled: “The World of Chemistry” from the Annenberg/CPB Collection. Each is about 30 minutes in length. There is only one copy of each, so return promptly when done.
