1. Balancing Equations

2. Conservation of Mass
The law of conservation of mass states that mass is neither created or destroyed in a chemical reaction
If you light a match, the match will get smaller. However, the match is simply being converted into an equal amount of gas particles
Total mass of the reactants = Total mass of products

3. Conservation of Mass cont.

4. Balancing Chemical Equations
We need to be able to show that mass between the reactant and products is conserved when we create chemical reactions
This is why we balance equations

5. How to Balance Equations
Given your reactants, create a product formula that has the same number of atoms per element in your reaction
