Answer

Brief Explanations:

A chemical change is characterized by the formation of a new substance. When magnesium burns, a white - substance (magnesium oxide) is formed, which is a new chemical compound. Reaching a high temperature, melting, or being malleable are physical properties or physical changes, not chemical changes.

Answer:

because a new substance is formed
