Question

What kind of chemical reaction is CO2 + H2O > H2CO3

Answer 1

Explanation:

What type of reaction is co2 h2o h2co3?

The H2CO3 → CO2 + H2O decomposition reaction in the presence of three water molecules can be considered as the participation of the third water molecule in all the reaction pathways which have been considered above in the case of the two water molecule-assisted H2CO3 → CO2 + H2O decomposition reactions.

Answer 2

The chemical reaction $CO_{2}+H_{2}O$ → $H_{2}CO_{3}$ is a combination reaction.

A combination reaction is a reaction in which two or more reactants react to form a single product. Here, as we can see carbon dioxide and water reacts to form carbonic acid.

Carbonic acid is a weak product and it further dissociates into hydrogen ion and  bicarbonate ions as follows:

$H_{2}CO_{3}$ → $H^{+}+HCO_{3}^{-}$
