Question

which statement describes a chemical property of water?
it reacts with sodium metal.
it has a melting point of 0°c.
it has a density of about 1 g/ml.
it is clear and colorless.

Explanation:

A chemical property describes a substance's ability to undergo a chemical change or reaction. Physical properties are observable or measurable without altering the substance's chemical identity. Melting point, density, and appearance (clear/colorless) are all physical properties. Reacting with sodium metal is a chemical change, as it forms new substances (sodium hydroxide and hydrogen gas).

Answer:

A. It reacts with sodium metal.
