Dear Student,

EXAMPLES OF CHEMICAL CHANGES

A new compound (product) results from a chemical change as the atoms rearrange themselves to form new chemical bonds.

• burning wood
• souring milk

• digesting food
• cooking an egg
• heating sugar to form caramel
• baking a cake
• rusting of iron

• crumpling a sheet of aluminum foil
• melting an ice cube
• casting silver in a mold
• breaking a bottle
