Question

physical vs. chemical edition directions: put a star (%) or a check (✓) in the correct column to classify the provided example. part 1: classify the following as a physical property or a chemical property. example physical property physical change chemical property chemical change density flammability wood burning resulting in a pile of ash reactivity an iron nail rusting crushing a can oxidation state a precipitate forming

Explanation:

Physical properties can be observed or measured without changing the substance's chemical identity. Chemical properties describe a substance's ability to undergo chemical changes. Physical changes don't alter the chemical composition, while chemical changes result in new substances. Density is a physical property as it can be measured without changing the substance. Flammability is a chemical property as it involves a substance burning (a chemical change). Wood burning is a chemical change as new substances (ash) are formed. Reactivity is a chemical property. Rusting of an iron nail is a chemical change. Crushing a can is a physical change as the can's chemical composition remains the same. Oxidation state is a chemical property. Precipitate - forming is a chemical change as a new solid substance is formed.

Answer:

Density: Physical Property
Flammability: Chemical Property
Wood burning resulting in a pile of ash: Chemical Change
Reactivity: Chemical Property
An iron nail rusting: Chemical Change
Crushing a can: Physical Change
Oxidation state: Chemical Property
A precipitate forming: Chemical Change
