How does matter change during a chemical reaction?

What happens to matter during a chemical reaction? During a chemical reaction atoms are regrouped or rearranged. Atoms are never created or destroyed during chemical reaction but at least one chemical bond is broken or formed. A chemical change produces a new substance, while a physical change does not.

Explanation:

Chemical reactions involve combining different substances. The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance.
