General Chemistry - 11/15 - 11/20 Material

Hello all.  You are currently studying for or finishing up your 1st trimester finals....but the science must go on.  For the brief time we are together before Thanksgiving Break, we will be looking at trends within the periodic table.  Please review the Prezi linked in the General Chemistry Study Resources Page.

Here are some other resources that will prepare you for class:

Summary of the general pattern for Periodic Trends

Periodic Trend PowerPoint with good pictures/graphs (movie links do not work)

More movies/animations than you have time to watch.  Pick the one(s) you think will help the most.


We will then be moving on to Similarities/Differences in Ionic vs Covalent bonding.  I would also read the book, watch the Prezis, and/or find some similar resources linked above to be ready for class.

GENCHEM - Lewis Structure Practice

Here is a multiple choice Lewis Structure practice website.  It does ask for some Lewis Structures that are outside of the scope of GenChem, so skip those.  Lewis MC

Here is a pdf for Lewis Structures

GenChem QUIZ - TOMORROW 10/12/2012

Our quiz tomorrow will cover the following topics...

Moles, Mole Conversion, Metric System

Here is a packet containing a metric ton of practice problems WITH ANSWERS - and some typos!.  I will be selecting from this packet EXACT questions that I will use for your quiz.  Note: this packet does not follow two of our rules.  Remember, when determining molar mass (molecular weight) round to two numbers past the decimal when using the average atomic masses on the periodic table.  Also, the answers on this sheet are not rounded to the correct number of significant figures.  Think about that as you compare your answers to the answer keys.

QUIZ REVIEW PACKET

AP CHEMISTRY - LAB TOMORROW

You will be designing and executing a lab tomorrow to determine the UNKNOWN concentration of a specific colored electrolyte solution.  I have provided you a few resources to get your mind going.  You will not know the electrolyte until tomorrow.  You will have a stock solution of KNOWN concentration already created.  Your goal will be to determine the unknown concentration that I give you.  The following links include a video, a student written lab report and a 'cook book' lab from another AP class.  The last link is a prezi used to describe Beer's Law.  Use them wisely to develop your method.

Heat of Formation of Magnesium Oxide

GENERAL CHEMISTRY - Practice for Quiz

Isotopes and Ion worksheet - This worksheet uses some different vocabulary.  They refer to 'isotope notation' where I would use the term Nuclear Symbol.  They also combine Nuclear Symbols with Ions which usually are not written together.  Give it a shot.

Naming Compounds/Molecules and Writing Formulas Worksheets: This link contains MANY worksheets.  I would definitely do the second to the last one listed.  On this worksheet skip #16. 

REMINDER GEN CHEM QUIZ ON SEPT 11th

If your class drops on the 11th, your quiz will be on the 12th.  Good Luck

AP CHEM LAB - ANION IDENTIFICATION WRITE UP

For THURSDAY - Turn in a sheet of paper that contains the following:

Unknown Letter and which Anion you believe it to be (i.e. Unknow J is the K+ ion)

Net Ionic equation that describes the reaction you witnessed in the test tube (look at the reagents in the procedure for help)

A paragraph that discusses the error that could have occurred in this lab that may lead you to a false identification.  In this paragraph suggest methods that could be taken next time to eliminate these errors.
