					       Chemistry 123 - General Chemistry III
                   Winter 2011

 Instructor:      Dr. Jeffrey A. Hurlbut

 Office:   CB 388

 Office Hours:    1:00 - 1:50 M, W & 11-11:50 F

 Office Telephone Number: (360) 650-2242 (I will
 not be able to return most out of area calls due to expense).

 Final Exam: 3:30-5:30 pm Monday 3/14/2011
                     Introductory Material

 The lecture notes are in PowerPoint format.             You need
  PowerPoint to look at & print the notes. If you do not have
  Microsoft Office then: 1) obtain a free compatible program such as
  OpenOffice on the web; 2) obtain a free PowerPoint viewer from
  the Microsoft web site; or 3) access the notes from a campus
  computer lab that has PowerPoint. You also need Adobe Reader
  which is free: http://www.adobe.com/products/reader/

 I suggest printing lecture notes in "handout," three per page, BW
  format; this allows space for writing. These lecture notes, along
  with the text & homework are the main source of exam questions.

 Course Requirements: 1) C grades in chemistry 121 & 122; 2)
  Text: General Chemistry, 9th Edition by Ebbing & Gammon
  (2009); 3) dedicated lab notebook; 4) attendance in lecture and
  lab; & 5) passing grade on the lab safety quiz before 12 noon,
  Thursday 1/13.
                           Internet Addresses
 Note: There are three ways to get most class material - 1) direct address; 2)
  my web site; & 3) Blackboard. The direct internet addresses are given below.

 Email:        Hurlbut@chem.wwu.edu
  Please use carefully – I have over 100 students per quarter, and I can only
  devote a few hours per week to online questions. It would help if you place
  Chem 123 in the subject line.

                                 Homework
 There are two types of assigned homework:

   1. End-of-Chapter Homework: The second page of each lecture note series
      contains a list of suggested homework problems. Do these by the time I
      finish the lecture over that section. I will devote lecture time to answering
      questions over these. These will not be graded or turned in, but they are
      important & may appear on the exams.

   2. Online Homework: The first three assignments will be graded and will
      count as 13 % of your grade.                You can access these at:
      cobalt.chem.wwu.edu/JHurlbutHW/lessons.htm Answer them when you
      have mastered the material. There is no time limit except for the deadline
      which will be announced in lecture as well as given on Blackboard. The
      deadline is firm, and NO excuses will be accepted if you miss the deadline.
      Finish these well before the deadline. Make a copy of these the first time
      you access them for study purposes; they will be offline after the deadline.
      Drop by my office if you have questions on the online homework - BUT you
      must have your work neatly displayed, labeled and with units.

                    Laboratory Safety Quiz
Mandatory safety quiz - a tutorial and the quiz are available
 at: http://cobalt.chem.wwu.edu/SafetyQ/GCqlink.htm The
 login is your student ID without the “W” and without the
 numbers after the last dash. Password = last two ID digits
 & first two letters of last name.

Example:     W00182234-11          Jack Smith
             ID = 00182234     &    PW = 34Sm

A 30 minute time period starts when you enter the lab quiz.
  You can take it the next offering; however, the passing
  grade becomes higher. Passing grades: 1st = 80% (until 5
  PM 1/7); 2nd = 84% (5 PM 1/7 to 5 PM 1/11); and 3rd = 88%
  (5 PM 1/11 to 12 NOON Thursday 1/13/2011). You must
  pass this lab safety quiz in order to continue in the course.
  Note: you need to study the tutorial slides before starting
  the 30 minute quiz.
                               Laboratory
 Lab Safety: Pass Lab Safety Quiz. Mandatory; see the previous slide.

 Requirements are: goggles always on; no short pants, short skirts, or
  open shoes; no food or drinks in the lab; all beakers/flasks must be
  labeled; clean entire work area before leaving.

 General Information: The experiments were selected to emphasize a
  variety of analytical concepts and techniques. Much of the work will be
  done independently. You will be graded over your calculations, accuracy,
  precision, significant figures, organization & notebook. Information is
  at: http://cobalt.chem.wwu.edu/labs/Chem123/ Download, carefully read, all
  introductory lab material before the first lab. Bring your notebook to all
  labs and record information directly into notebook - do not use scratch
  paper for recording lab data.

 Lab Notebook: Hard-bound (9.75” x 7.5” recommended) - Name on outside

 A brief procedure must be completed and in your notebook by the
  beginning of each lab (including the 1st lab). Detailed instructions
  concerning the lab notebook are in the introductory lab material - you
  must read this material before the first lab. Notebook will be graded.

 Lab times are firm & you must be done & out 10 min before the last hour.
                                    Laboratory
 Lab Notebook Continued: Your notebook should contain:

   1. Pre-lab. Before the lab: complete any pre-lab & write-up; place in your
      notebook; this includes a) title, b) any prelab calculations; c) short purpose,
      d) an outline of the procedures, and e) room for addition of graded result
      sheet & a short summary statement.

   2. Data & Observations. During the lab, you will record observations, dates,
      data, and calculations in your notebook in ink. Be sure to carefully read the
      introductory material for comments on SF, units, dates, examples, etc. Do
      not erase - cross out with a single line, and do not place data on temporary
      paper; data is always to be labeled and entered directly into your lab book.

   3. Data & Results Summary Sheet. Obtain & fill in Data & Results Summary
      Sheet for each experiment. Turn this sheet in the next lab period (the F- lab
      is due at the end of that lab) . I will grade and return the sheet the following
      lab period; attach this in your notebook. Also write a 1-2 sentence
      summarizing the results for each lab.

 Lab Grading:
  Each Data & Results Summary Sheet will be graded. The grade will include:
  calculations, accuracy, precision, completeness, grammar, significant figures
  (SF), etc. The lab notebook will also be graded.
