From this list of substances: oxygen, sulfur, water, sodium hydroxide, carbon monoxide (IV), potassium oxide – select those with which the oxide interacts. sulfur (IV). Write down the equations of the corresponding reactions.

Potassium oxide and tetravalent sulfur oxide enter into a chemical reaction. The potassium sulfide salt is formed.

K2O + SO2 = K2SO3.

Oxygen with tetravalent sulfur oxide enters into a chemical reaction. Hexavalent sulfur oxide is formed.

2 SO2 + O2 = 2 SO3
Sulfur oxide tetravalent and sodium hydroxide form after a chemical reaction water and sodium sulfide salt.

2 NaOH + SO2 = Na2SO3 + H2O
A chemical reaction takes place between substances such as tetravalent sulfur oxide and water. Thus, we get sulfurous acid.

SO2 + H2O = H2SO3.
