1) If you were to mix two substances together what might be some things to look for to see if there is a chemical reaction taking place? List them.
2) If you were to shrink yourself down to the size of a molecule what should you see happening during a chemical reaction?
3) Which chemical property can only be determined by observing harm to living things?
