Chemical reactions are used in many ways, but the most important ones are the ones that keep us alive.  Photosynthesis is a chemical reaction!  The chemical formula for Photosynthesis is carbon dioxide plus water, which equals glucose and oxygen.

Photosynthesis provides us with food to eat and oxygen to breathe.

Respiration is another example of an important chemical reaction that keeps us alive.  The respiration chemical formula is glucose plus oxygen, which equals carbon dioxide and water.

Respiration releases stored energy so people can read, eat, write, and LIVE!
