CHEMICAL CHANGE A chemical change is a change in matter in which the substance that makes up the matter changes into something else with different chemical AND physical properties!

**A NEW SUBSTANCE IS CREATED!!** All reactions involve energy (light,

sound, or thermal) - Some require it to start, some give off energy, and some absorb energy.
