You can review the mole concept at the site called Chem Team.

Semester One Exam Review
There are two websites that contain very good review material.
 * 1) The New York State Regents Exams are written by the State of New York. If you practice the multiple choice questions, especially, you will be able to review the concepts and vocabulary from units one and two.
 * 2) Ohio State University has on-line chemistry quizzes. You have to select topics that you recognize, and some of the questions are very challenging (they are written for university students), but in general you will find the quizzes in the first two quiz banks very useful. The link I have given takes you to the home page of the OSU Department of Chemistry and Biochemistry. To get to the quizzes, go to the quiz bank link in the "Online Resources" section of the home page.

My students have used both of these sites for more than a decade, and they tell me these sites are very useful.

Unit III - Compounds
The main concepts that make up this unit are listed in the table below, along with the page numbers in the book which correspond to this concept. The worksheets related to each concept are also posted in the table, and a link to ChemTeam is provided. Pages 212-215 and pages 220-224 of Section 8.2 ||  || On the ChemTeam equations page, there are 110 equations which you can balance for practice. They are shown in the lower left quadrant of the page, in the "Problems" section. || The quiz bank called "Chemical Equations" has many great questions. Quizzes 1 through 4 will help you practice balancing. I've listed them below and added comments. || Pages 149-153 of Section 6.4 Pages 158-159 of Section 6.5 || || On the ChemTeam nomenclature page (nomenclature = "naming"), there are four sets of 30 practice problems. To find these practice problems, open the following tutorials. The practice problems are at the bottom of each tutorial page. It's a good idea to read the tutorials, too. The quiz bank called "Chemical Equations" has many great questions. Quizzes 5 through 10 will help you. I've listed them below and added comments. || __Quizzes and Test for Unit III__

Unit IV- The Quantum Model of the Atom
The University of Colorado has a physics website that guides you through the discovery of the quantum model. When you get to the main page, find the Science Trek section and choose the link called "Click here to see the applets from this section." On the list that appears, choose the applet called electron orbits. You can create an atom by "throwing" electrons into orbit around a nucleus.

Here is a powerpoint explaining the model of the atom.

__A Simulation of the Hydrogen Atom__
Click on this link and use the simulation to complete the worksheet.

In the table below, you can follow links to see pictures of orbitals. The pictures were generated by Jim Holler at the University of Kentucky. The equations used to generate these pictures are shown at this link. here is the link to the [|chem quiz] website This powerpoint explains how to draw the structures of molecules. The following sections from the text will be covered on the test. Chapter 13, all sections Chapter 14, section 1, describing the structure of the periodic table Chapter 15, sections 1 and 2, describing ionic compounds

Unit VI - Molecules and the Gas State
The ideas in this unit are described on the following pages of the textbook:
 * Section Number || page numbers || Title and contents ||
 * 16.1 || 437-443 || the first half of this section describes covalent bonding in detail, but the Advanced Placement topics covered past page 444 will not be on the exam (coordinate covalent bonding, bond dissociation energy, resonance, and exceptions to the octet rule). ||
 * Table 16.2 || 445 || a good summary of the most common molecule structures ||
 * 16.2 || 455-456 || VSEPR Theory, this section explains the logic used to determine the shape of a molecule ||

Directions for drawing Lewis structures:
 * 1) Connect all atoms to the central atom with single bonds.
 * 2) Complete the valence octets on all atoms by adding unshared pairs to the structure.
 * 3) TEST: add up the total number of valance electrons possessed by all the atoms in the molecule. Does the total number of electrons present in the structure equal this sum of valence electrons?
 * 4) IF the answer is yes, your structure is acceptable.
 * 5) IF the answer is no, re-draw the entire structure to include double or triple bonds instead all single bonds. Return to step 2.

**Semester Two Exam Review**
Write two questions from each unit and send them to Mr. Robinson. The questions should be based on material that has appeared on past tests. One question must be a calculation, and the other can be a vocabulary review. The format of the question can be a calculation, true-false, or multiple choice. Do not do short answer questions. Send the questions and answers in text format to Mr. Robinson: trobinson@scischina.org. The subject line of the e-mail should be "chemistry exam review." We will use these questions to make a quiz bowl powerpoint that everyone can use to review the material.
