Chemical Reactions

What happens to atoms during chemical reactions?

• There needs to be more than one reactants.

• The atoms rearrange to form a new product.

• The temperature when a liquid changes into a gas or a solid turns into a liquid. 

• They have different properties or different groups of atoms.
