Question:
What are the observable changes that can indicate that a chemical change has occurred?
Physical Change and Chemical Change:
Physical changes involve a change in form but not in the composition of the substance involved. A phase change is a physical change as the identity of the substance involved does not change. An example of a physical change is the melting or freezing of water. As opposed to physical changes, chemical changes involve the formation of products that are different in identity with the reactants.
