Answer:

It does not always retain the properties of the substances that make it up

It requires heat energy to make

Explanation:

A compound is a chemical substance composed of two or more kinds of atoms or elements joined together in a definite grouping.

The properties of compounds are distinct from those of individual elements that are combined in its make up.

  • To produce a compound, a chemical change must take place
  • As  with most chemical changes, heat is required to drive the change.
  • So, to form compounds, some amount of heat is needed to cause the change.
