Matter
A. Pure Substance: doesn?t change composition, fixed properties
1. Molecule: covalent bond
2. Compound: ionic bond
B. Mixture: two or more pure substances
1. Properties change
C. States of Matter
1. Solid: strong attraction, low kinetic Energy, constant volume and shape
2. Liquid: constant volume, shape changes
3. Gas: no set volume or shape

The Mole
The Mole:
The amount of a substance that contains the same number of ?entities? as 12 grams of Carbon-12 (C-12)
1 mol C-12 = 6.022 x 1023 Carbon atoms
1 mol H20 = 6.022 x 1023 molecules H20
1 mol H20 = 2 mols H and 1 mol O (ratio never changes)
Definitions
The mole: the SI unit for amount of substance
Specifies the # of objects in a fixed mass of substance
Avogadro's #: 6.022 x 1023
All isotopes are considered to have the same atomic mass

Federalism
Chapter 3 ? the relationship between state & national government
The Basic Idea
Power is shared between STATE & FEDERAL Gov?ts
The Federal Gov?t was designed to have slightly more power than state gov?ts, and it has evolved since 1789 to hold a major advantage over states
(enumerated powers > reserved powers)
Aside from the Constitution, the Federal Gov?t also hold tremendous power over states b/c of their ?power of the purse?
serves as an extra system of checks
The Study of American Gov?t
APUSG Chapter 1
Four Key Concepts
The United States is a representative democracy.
In the American system, there are those who exercise power because they have the legitimate authority to do so, and those who exercise power without legitimate authority.
Because of this, there is ongoing debate over how political power is distributed. Your chapter presents four different theories on how political elites impact government and politics.

5 Basic Course Concepts
AP Gov?t
Introduction
Before we begin the study of US government & politics in your textbook, we will take the first 3-weeks of the school year to master 5 basic concepts regarding how the American system works
Each topic will take one day of class instruction and will require a short classwork/homework assignment
