Final answer:
A chemical property is a characteristic of a substance that describes how it changes or reacts with other substances. An example of a chemical property is the boiling point, which is the temperature at which a substance changes from a liquid to a gas phase.
Step-by-step explanation:
A chemical property refers to a characteristic of a substance that describes how it changes or reacts with other substances. An example of a chemical property is the boiling point. The boiling point is the temperature at which a substance changes from a liquid to a gas phase. It is a chemical property because it is determined by the composition and bonding of the substance. For instance, water has a boiling point of 100 degrees Celsius because of the hydrogen bonds between its molecules.
An example of a chemical property is flammability; this refers to a substance's ability to burn in the presence of oxygen. Chemical properties describe the potential of a substance to undergo chemical changes during reactions. By contrast, boiling point and melting point are examples of physical properties, which can be observed without changing the substance's identity. When iron reacts with oxygen and water to form rust, it demonstrates a chemical property because a new substance is produced. Similarly, zinc reacting with hydrochloric acid to release hydrogen gas is another example of a chemical property as there is a change in composition and a new substance is formed.
