Question

Chemical changes ________ involve the breaking and making of chemical bonds.

Answer 1

The correct answer that would best complete the given statement above would be option A. Chemical changes ALWAYS involve the breaking and making of chemical bonds. When there is chemical change, a new compound is being formed. If a new compound is not formed, then it is not considered as a chemical change. When a new compound is formed, therefore, there is the breaking and making of chemical bonds. Hope this helps.
