..... Check this location often.  This location will contain old quizzes, tests, handouts study guides and the laboratory manual.

Prerequisites:            F Mathematics 115 (Elementary Algebra) or 123B (Elementary and Intermediate Algebra II) with a grade of “C” or better, or appropriate Math placement results.

Required Materials:  FText (Required NOW).  General, Organic, and Biological Chemistry by Timberlake, 1st Edition, and Custom Published for LA Mission College.  This is the class textbook and is required.  A copy of the textbook is available on Reserve in the Library.

F Periodic Table: This is available in the LAMC bookstore. The periodic table will be one of your greatest resources.  You should have one available at all times.  One is provided with this handout.  During a test, you will be provided one as part of the test.  Please note that the periodic table provided during a test will NOT have the element names on it.

F Scientific Calculator (Required NOW).  I recommend that you purchase a Hewlett-Packard 10s calculator (price should be between $10 & $20).  This will be the calculator that is discussed in class to answer questions.  (Note that HP-10s & HP-10S+ are both acceptable.)

Class Description:... Chemistry 51 is an introductory class in general chemistry and is designed for students in the following majors: Nursing, Allied Health Sciences, Dietetics, Physical Therapy, Food Science & Environmental & Occupational Health.  This course may also be taken to satisfy the Physical Science requirement for General Education.  Chemistry 51 at LA Mission College is equivalent to Chemistry 103 or Chemistry 105 at CSUN.

SLO:.......................... Student Learning Objectives:

F Conceptualize, model and explain chemical processes qualitatively at the molecular level.

F Extract appropriate information, analyze and synthesize experimental results to reach correct conclusions.

F Perform laboratory techniques safely and accurately and maintain a laboratory notebook according to standard scientific guidelines.

College Student Learning Objectives:

F Written and Oral Communication

F Problem Solving

F Math Competency

Assessment Method:

F Embedded questions in exams.

F Evaluation of lab reports and lab notebooks.

 

Homework:............... Homework will be given for each chapter.  The test and final questions will come from these questions.  The assignments will NOT be collected but you are expected to have completed them.  I will know if you have completed the homework when I grade your tests.  Please note that the test questions will come from the homework.

 

Attendance:.............. This will be taken at the beginning of each class meeting.  Attendance will be utilized when determining the final grade for borderline students and will count for 5% of your final grade.  Please note that the material will come very fast and missing a class will be detrimental to your understanding of the material and your final grade in the class.

 

Chemistry is a demanding subject.  You cannot afford to be absent if you wish to do well in this course.  Please remember that there is no make up for missed laboratory work.

 

You will not be automatically dropped if you do not attend.  If you decide to not complete the class it is your responsibility to drop.

 

Tests:........................ The questions will primarily come from the homework questions from the book.  The tests will count for 40% of your final grade.  No make-up exams are given for students being absent on the day of the exam.

 

Final:......................... The final questions will primarily be taken from the tests.  The final will be cumulative and cover all tests.  The final will count for 15% of your final grade.    Failure to take the final exam will result in an automatic fail in the course.

 

Grading:.................... The grade you will earn will be based on the following scale and a semi-modified scale.

A         90% - 100%

B         80% -   89%

C         65% -   79%

D         55% -   64%

F           0% -   54%

I guarantee that you will receive at least the above grade if not higher due to modifications of the curve to fit the class performance.

 

Grade Breakdown:... The final grade is based upon your grades in both the laboratory and lecture.

How to sUrvive & even excel in Chemistry 51

 

 

Chemistry 51 is a demanding course.

·        Chemistry demands considerable time due to the sheer volume of work you must process for laboratory and lecture. It demands a lot of effort to understand and learn the many new concepts presented in the course. You can have a successful, even interesting semester if you practice some of the following hints.

·        Please note that each lecture builds on the previous lectures.

 

Work on chemistry every day.

 

·        Study groups with your fellow students are good!  If the class is easy for you, your time with other students will be helpful for you to verify your knowledge and help them learn.  If the class is challenging then working with others will help you understand what is important, what you spend time on, and what can be learned after you graduate.

·        Do just two or three problems or read just a few sections of the current chapter each day. You will often need to try a problem several times before you fully understand it. You will need to read the text several times before you really know the material.

 

You cannot cram Chemistry! Don’t try!

 

·        Try to stay ahead of lecture. Skim the anticipated lecture topic the day before class. Then you will know what is in the book and need not take so many notes. You then can listen and think during lecture. Carefully read the examples and solved problems in the text. Cover the author’s solution and work them yourself immediately after reading the text. Do the suggested end of chapter problems. You cannot solve test problems quickly and efficiently without lots of practice.  If you cannot solve a suggested problem, or don’t understand it, reread the appropriate section in the text and review your lecture notes. Look for a similar problem among the text’s examples. Think about it for several days.

 

Ask for help

 

·        Ask for help to get started from your instructor, a tutor, or a fellow student.  Use the internet and try various websites.  One that I find very helpful is the Khan Academy.

 

Look for connections

 

·        Look for connections between the current lecture topic and previous topics or your prior knowledge of chemistry or physics.  Look for practical applications of what you are learning.

 

Finally, do not panic.

 

·        Take the course one step at a time and let your understanding grow. You will be amazed at how much material you have assimilated by semester’s end.

Uncertainty and Significant Figures

Calculations

 

  Multiplication and Division

 

1.   The least accurate number is the number with the least number of significant figures.

2.   The answer (product or quotient) can have no more significant figures than the least accurate number.

 

      Example:

Calculate the volume of a rectangular solid that has a length of 4.16 cm, a width of 2.2 cm, and a height of 2.00 cm.

 

      Volume = Length x Width x Height

 

      Volume = (4.16cm) (2.2cm) (2.00cm)

                                        LAN

 

      Volume = 18.304 cm3 (incorrect)

 

      Volume = 18 cm3 (correct)

 

Fewest significant digits to the left of the decimal point = Significant digits to the right of the decimal point

 

 

  Addition and Subtraction

 

1.   The least accurate number is the number with the least number of digits following the decimal point.

2.   The answer (sum or difference) can have no more digits following the decimal point than the least accurate number.

 

         Example:

                        What is the total mass of a mixture made by mixing the following substances?

 

                                         212             g water (LAN)

                                              1.8         g salt

                                              1.88       g sugar

                                         ____________________

                                         215.68        g (incorrect)

                                         216             g (correct)

 

 

The easiest way to do this is shown above.  Note: It is very easy to mix this up with multiplication and division.

F Safety Goggles:  Safety goggles are available for purchase in the LAMC Bookstore.  You may keep your goggles locked in your laboratory locker.  Goggles must be able to protect your eyes from chemical splashes.

F Periodic Table: This is available in the LAMC bookstore. The periodic table will be one of your greatest resources.  You should have one available at all times.

F Scientific Calculator (Required NOW).  I recommend purchasing one from the 99¢ or dollar store.  Simpler is better, the more complicated calculators take longer to learn and do not provide any better answers.

Laboratory Reports:... Laboratory reports are due one week after the completion date of the experiment.

Late reports will be subject to a 25% per week late penalty.

Laboratory Exams:..... Exams will be given on the scheduled date only.  These laboratory exams will be closed book, closed notes.  You will have your laboratory notebook as the only resource. No makeup exams will be given.

Safety Goggles:......... During the experiments, unless specifically told by your instructor, you must ALWAYS wear safety goggles while in the laboratory.  Failure to wear safety goggles will dismiss you from the laboratory.

Safety Rules:.............. Failure to follow the safety rules will result in your dismissal from the laboratory.  Safety is the responsibility of all persons within the laboratory.  Make sure you read the Safety Rules and Regulations and follow all guidelines.

Experiments:............. Please note that the lab experiments may be different from the videos.  You are to follow the written experiment only.  The videos are provided for an overview of the experiment only.

Lab Notebook:........... Before starting your laboratory notebook, read this section and the next page completely.  The laboratory notebook will be collected and graded twice throughout the semester.  Anyone not having the laboratory notebook before the second day of class will be excluded from the laboratory.  All notes MUST be taken down in the laboratory notebook.  You will write your data in the notebook and then transfer the data to the laboratory report form.  The grading of the laboratory notebook will be done on the form to the right:

1.   Always write in ink.  (NO PENCIL!)

2.         Write only on the right-hand side of the page.  (The left-hand side of the page should be used for calculations, notes, etc…)

3.   Number all right –hand pages in the upper right-hand corner.

4.         Just beneath the page number indicate the date on which the laboratory work was done.  When the experiment work is done on two different dates, indicate the second date (right –hand margin) at the point where the second day’s work begins.

5.   The laboratory notebook is an original permanent record.  This means several things:

            a          You must write down all data directly (in ink) in the lab notebook.  There will be a grade penalty when a student disregards this rule.  (The rule means:  no writing in pencil; no writing on the lab report sheet, on pieces of paper, etc…)

            b.         There will be no erasures, no “white out”, and no missing pages.  One thin line may be used to cross out offending material.  (Later you may discover that you need this information and this way you can retrieve it!)

            c.         Never Remove a Page from the Laboratory Notebook.  (At some point this practice could have legal implications; patent fights are won and lost on the legitimacy of lab notebooks.)  If you do make a dreadful error and would like to remove a page, do the following: draw a diagonal line across the entire page.

            d.         Holes and spots from chemical spills are legitimate artifacts; do not worry about them.

 

Format for the Laboratory Notebook

1.         Leave one or two pages at the beginning for a Table of Contents.  On this, list each experiment title (as you perform the experiment) and in a column at the right of the page, give the page number where the experiment write-up starts.

2.         Begin each experiment on a fresh right-hand page.  Each write-up includes:

            a.         Title:  At the top of the page give the title of the experiment.

            b.         Page number and date:  At the top right-hand of each page.

            c.         Purpose:  Describe what you are doing and why.  Describe what information you are attempting to gain by doing this experiment.

            d.         Procedure: Give references to the location of the procedure in the text and any deviations from the procedure in the text.

            e.         Data: This includes all the observations, measurements, etc… that you make in the laboratory.  The data should be presented in tabular form.  Check the report sheet to get ideas from the types of tables that are helpful for presenting data for that particular experiment.

            f.          Results: These include all the things that you have calculated from the data.  Note:  results are not calculations, but calculations based on data give results.

            g.         Discussion & Conclusions:  A short paragraph discussing the results of the experiment.  This section should answer the questions from the “Purpose” above.  This is the place to mention significant sources of error and the effect they have on the results
