How do you know if an equation is balanced? 
It has the same number of atoms on both sides of the arrow.

Name an example of a chemical reaction

Change in color

Gas production

Precipitate

Change in temperature, etc

How many valence electrons does Chlorine (Cl) have and how reactive is it?

7 valence electrons

High Reactivity

400

Why is color change not always a chemical change?

If the color change is expected, then its not a chemical change, its physical.

Example: Mixing two clear liquids and the solution turns pink. (Unexpected)

Mixing a green food coloring into water and it turns green. (physical change)
