Answer 2

Answer:

Chemical change happens when one chemical substances is transformed into one or more different substances ,such as when iron becomes rust .

Explanation:

Chemical change occurs through the process of chemical reactions ,and the rustling substances have the different properties because their atoms and molecules are arranged differently .

A chemical change is different from a physical change ,which doesn't rearrange atoms and molecules and produce a completely new substance. Ice melting into water is an example for physical change
