Question

determine whether each statement is a description of a physical property or a chemical property. paper burns readily in air. ( ) physical ( ) chemical salt is soluble. ( ) physical ( ) chemical

Explanation:

For "Paper burns readily in air":

A chemical property describes a substance's ability to undergo a chemical change (reaction) to form new substances. Burning involves a chemical reaction (combustion) where paper reacts with oxygen to form new products (like carbon dioxide, ash). 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. Solubility (ability to dissolve) is a physical property as dissolving salt doesn't change its chemical composition (it's still salt, just dispersed in a solvent).

Answer:

chemical

For "Salt is soluble":
