Final answer:
The chemical property of aspirin is its flammability, as it describes the substance's ability to chemically react with oxygen during combustion.
Step-by-step explanation:
The chemical property of aspirin would be its flammability.
A physical property is a characteristic that can be observed or measured without changing the substance's chemical identity. Examples include melting point, solubility in water, color, and taste. A chemical property, on the other hand, is an attribute that can only be observed by changing the chemical identity of the substance, such as its potential to undergo a specific chemical change.
From the examples provided, flammability is a chemical property because it describes the substance's ability to catch fire and react with oxygen to form new substances. Properties like melting point (2), solubility in water (7), and color and taste (7) are all physical properties as they can be determined without inducing a chemical reaction.
