which of these is an example of a chemical property?
neon is a colorless, odorless gas.
a piece of coal burns.
ammonia gas has a pungent odor.
iron is magnetic.

Explanation:

A chemical property describes a substance's ability to undergo a chemical change or reaction. Color, odor, and magnetism are physical properties (observable without altering the substance's chemical composition). Burning involves a chemical reaction where coal reacts with oxygen to form new substances, so this is a chemical property.

Answer:

A piece of coal burns.
