Final answer:

Water separating into hydrogen and oxygen and water expanding when it freezes are examples of chemical properties.


Step-by-step explanation:

A chemical property of water is that it can separate into hydrogen and oxygen. This is a chemical reaction known as electrolysis, which occurs when an electric current is passed through water, resulting in the formation of hydrogen gas and oxygen gas.

Another example of a chemical property of water is its ability to expand when it freezes. This is due to the arrangement of water molecules in solid ice, which forms a lattice structure that takes up more space than liquid water.

On the other hand, the boiling point of water at standard atmospheric pressure is 100°C, and this is considered a physical property rather than a chemical property. Physical properties are characteristics of a substance that can be observed or measured without changing its chemical composition.
