Which option is an example of a chemical property? density color melting point ability to decompose

The ability to decompose

Explanation:

A property is a chemical property when it changes the chemical structure of a substance after a reaction.

Density and color are both physical properties.

Even though melting point may seem like a chemical property, when something melts, only the physical state changes, and the chemical structure does not change, and therefore, is a physical property.

The ability to decompose is a chemical property. When something decomposes, the chemical structure of many molecules change, and therefore, is classified as a chemical property.
