Explanation:

⇔

Hydrogen carbonate dissocates to form carbon dioxide and water. The acid (hydrogen carbonate) is in aqueous form and it dissociates to water (liquid) and carbon dioxide (a gas). It is also seen that the hydrogen carbonate is on the reactant side and it dissociates to produce water and carbon dioxide.

W is an aqueous reactant (a reactant undergoes changes in a chemical reaction

is a liquid product (product refers to the species produced from  chemical reaction)

is a gaseous product
