Question
determine whether each statement is a description of a physical property or a chemical property. sodium metal reacts vigorously with water to produce hydrogen gas. ☐ physical ☐ chemical steel is attracted to magnets. ☐ physical ☐ chemical done ✔ photo by david
For the first statement: "Sodium metal reacts vigorously with water to produce hydrogen gas."
A chemical property describes a substance's ability to undergo a chemical change (reaction) and form new substances. Sodium reacting with water to form hydrogen gas involves a chemical reaction (new substance, hydrogen, is formed), so this is a chemical property.
A physical property is a characteristic that can be observed or measured without changing the substance's chemical identity. Steel being attracted to magnets is a physical characteristic (magnetic property) that doesn't involve a chemical reaction or change in the steel's chemical composition, so this is a physical property.
