Introductory Material The address notes are in PowerPoint format.â  You require PowerPoint to look atâ & print the notes.â  If you don\'t have Microsoft Office then: 1)  obtain a free perfect program, for example, OpenOffice on the web; 2)  obtain a free PowerPoint viewer from the Microsoft site; or 3) get to the notes from a grounds PC lab that has PowerPoint. You additionally require Adobe Reader which is free: http://www.adobe.com/items/peruser/I recommend printing address notes in "handout," three for every page, BW design; this permits space for composing. These address notes, alongside the content & homework are the primary wellspring of exam inquiries. Course Requirements: 1)  C grades in science 121â & 122;â  2) Text: General Chemistry , ninth Edition by Ebbing & Gammon (2009);â  3)  dedicated lab scratch pad; 4) participation in address and lab; & 5) passing review on the lab wellbeing test before 12 twelve, Thursday 9/30 .

Last, most decisive test – 30%: Cumulative over sections 15 through 19 and all labs. 8-10 AM Tuesday, 12/7/2010 Lab – 17%: See the slide on the lab. Online Homework – 13%: Deadlines are Firm .

Slide 7

Laboratory Safety Quiz Mandatory security test - an instructional exercise and the test are accessible at: http://cobalt.chem.wwu.edu/SafetyQ/GCqlink.htm The login is your understudy ID without the “W” and without the numbers after the last dash. Watchword = last two ID digits & initial two letters of last name. Sample: W001822 34 - 11 Jack Sm ith ID = 001822 34 & PW = 34Sm A 30 moment time period begins when you enter the lab test. You can take it the following offering; nonetheless, the passing review gets to be higher. Passing evaluations: first = 80% (until 5 PM 9/24) ; second = 84% (5 PM 9/24 to 5 PM 9/28) ; and third = 88% (5 PM 9/28 to 12 NOON Thursday 9/30/2010) . You must pass this lab security test so as to proceed in the course. Note: you have to consider the instructional exercise slides before beginning the 30 moment test.

Slide 8

Laboratory Lab Safety: Pass Lab Safety Quiz. Obligatory; see the past slide. Prerequisites are: goggles dependably on; no short jeans, short skirts, or open shoes; no nourishment or beverages in the lab; all measuring utencils/carafes must be named; clean whole work territory before taking off. General Information: The analyses were chosen to underscore a mixed bag of systematic ideas and procedures. A significant part of the work will be done autonomously. You will be reviewed over your counts, exactness, accuracy, noteworthy figures, association, sentence structure & note pad. Data is at: gold.chem.wwu.edu/labs/Chem123/Default.htm Download, deliberately read, and carry all initial lab material with you to the first lab – including your committed, bound, page numbered ( by hand is OK ) lab note pad (9.75” x 7.5” prescribed). Lab Notebook: Hard-bound (9.75” x 7.5” suggested) - Name on outside A brief methodology must be finished and in your journal by the start of every lab (counting the 1 st lab) . Point by point directions concerning the lab note pad are in the early on lab material - you must read this material before the first lab. Scratch pad will be reviewed. Lab times are firm & you must be done & out 10 min before the most recent hour.

Slide 9

Laboratory Lab Notebook Continued: Your note pad ought to contain: 1. Pre-lab. Prior to the lab: finish any pre-lab & review; place in your note pad; this incorporates a) title, b) any prelab counts; c) short reason, d) a framework of the strategies, and e) space for expansion of evaluated result sheet. 2. Information & Observations. Amid the lab, you will record perceptions, dates, information, and computations in your note pad in ink. Make certain to painstakingly read the early on material for remarks on SF, units, dates, illustrations, and so on. Try not to delete - cross out with a solitary line, and don\'t put information on brief paper; information is dependably to be marked and entered straightforwardly into your lab book. 3. Information & Results Summary Sheet. Get & fill in Data & Results Summary Sheet for every trial. Turn this sheet in the following lab period (the F - lab is expected toward the end of that lab) . I will review and return the sheet the accompanying lab period; connect this in your scratch pad. Additionally compose a 1-2 sentence abridging the outcomes for every lab. Lab Grading: Each Data & Results Summary Sheet will be reviewed. The evaluation will include: computations, exactness, accuracy, culmination, sentence structure, huge figures (SF), and so on. The lab scratch pad will be evaluated.
