Answer: The product formed from the reaction of these two is sulfurous acid.

Step-by-step explanation:

When sulfur dioxide reacts with water molecule, it leads to the formation of an acid known as sulfurous acid.

The chemical reaction for the combination of sulfur dioxide and water follows the equation:


SO_2(g)+H_2O(l)\rightarrow H_2SO_3(aq.)

By Stoichiometry of the reaction:

1 mole of sulfur dioxide reacts with 1 mole of water molecule to produce 1 mole of sulfurous acid.

Hence, the product formed from the reaction of these two is sulfurous acid.
