![]() ![]() After the chemical change has occurred, the carbon atom bonds with two oxygen atoms. It starts out bonded to four hydrogen ions. Notice the black carbon atom in the image above. This is how plants turn carbon dioxide into oxygen you breathe, through breaking bonds! If a molecule or compound participates in a chemical reaction, the bonds are broken and recreated into a new substance. When you light a match, you are initiating a chemical reaction.
