Formation of new atoms
Explanation:
Matter cannot be created nor destroyed, but can be turned into different forms (energy). When this happens, it is referred to as a nuclear reaction.
Chemical reactions only involve the electrons surrounding an atom and the atoms around it.
Acids Lemons, oranges, vinegar, urine, sulfuric acid, hydrochloric acid
Bases Soap, toothpaste, bleach, cleaning agents, limewater, ammonia
The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids, as are carbonated beverages, tea, and battery acid. Common household bases include baking soda, ammonia, soap, and antacids. As you'll find, acids and bases really aren't that difficult to understand once you get the hang of them.
