1. Understanding Chemical Reactions
Physical Science
Chapter 10.1
Part 1

2. Chemical changes rearrange chemical bonds
Versus physical changes
Change one or more substances into different substances
Using chemical changes
To make new substances
Recognizing chemical changes
Bubbles
Temperature change
Color change
Precipitate

3. Your Turn What is the indication of a chemical reaction in: Glow stick
Toe warmer
Alka Seltzer
Rust

4. Products and reactants
Products on right side
Reactants on left side
Products may change phase in a reaction
Liquid + liquid may not produce a liquid
Start by counting the atoms in the products
Chemical reactions to not create or destroy matter
All atoms in the reactants must be identified in the produce

5. The products of the reaction
Figuring out the products
Chemical reactions rearrange atoms from the reactants to make the product
No new atoms are created!

6. Chemical Equations Understanding a chemical equation
Conservation of mass
Demonstrating conservation of mass

7. Your Turn Partner 1: Say one thing a chemical equation tells you
Partner 2: Add to their statement
Partner 1: Can you add anything to that?
