Definition & Meaning of Chemical Changes
A chemical change refers to a process where substances transform into different substances with distinct chemical properties. This transformation involves the breaking and forming of chemical bonds, resulting in new compounds. Unlike physical changes, which only alter the form of a substance without changing its chemical identity, chemical changes lead to a complete reconfiguration of the molecular structure.
Common examples of chemical changes include:
- Combustion: The burning of wood or gasoline produces carbon dioxide and water, demonstrating a clear chemical transformation.
- Rusting: Iron reacts with oxygen and moisture to form iron oxide, commonly known as rust, which is a different material than the original iron.
- Digestion: Food undergoes a series of chemical reactions in the body, resulting in nutrients being absorbed and waste products being excreted.
