What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as combustibility, reactivity, and acidity.

Front

What is an example of a chemical property?

Back

Combustibility is an example of a chemical property, as it describes a substance's ability to catch fire and burn.

Front

What is the difference between physical and chemical properties?

Back

Physical properties can be observed without changing the substance, while chemical properties can only be observed during a chemical change.
