B) Oil and water do not mix.
C) Pencil shavings float on water and do not dissolve.
D) Neutral water react s with carbon dioxide to form an acid solution.

Answer 1

Answer 2

Answer: D) Neutral water react s with carbon dioxide to form an acid solution.

Explanation: A physical property is defined as the property in which a change in shape, size takes place. No new substance gets formed while measuring physical properties.

Example: A) Salt dissolves in water.

B) Oil and water do not mix.

C) Pencil shavings float on water and do not dissolve.

A chemical property is defined as the property in which a change in chemical composition takes place. A new substance is formed while measuring chemical properties.

Example: D) Neutral water react s with carbon dioxide to form an acid solution.
