What is a chemical reaction?
The best way to tell if a chemical reaction has occurred is to see if the products have (changed/stayed the same).
What is changed?
The subscript in a formula tells you this.
How many atoms of a substance are in a compound.

What is a synthesis reaction?
This type of reaction gives off heat or energy.
What is an exothermic reaction?
This is a shorthand way to use chemical symbols and numbers to represent a substance.
What is a chemical formula?
This is what happens to bonds during a chemical reaction.
What is bonds break and make?
This type of bond is made up of a metal and non-metal.
What is ionic bonding?
