Answer:
Dissolution of carbon dioxide gas in water is both a physical and chemical change.
Carbon dioxide dissolves in water producing carbonic acid, also known as soda water.

There will be an equilibrium constant that will dictate the relative concentration of dissolved gas to the corresponding acid that is formed.

simply dissolve in water, depending on the partial pressure above the water, and Henrys law constant. This implies a physical change.

Explanation:
The gas simply dissolves in the water. You are correct that this step is a physical change. ... Once dissolved in water, some of the non-metal oxide will react with water to form an acid (sulfuric/sulfurous acid, carbonic acid, nitric/nitrous acid, etc.) and this is the chemical change that your book is referring to.
