Answer:

Because chemical bonds have been broken, and new substances (here, elements) are formed.

Explanation:

Chemical change is characterized by the formation of new substances, and the making and breaking of strong chemical bonds. Decomposition of a compound into its elemental constituents certainly falls under this umbrella. Therefore, you are quite correct to designate this transition as a chemical change.
