Write three reaction equations with So3.

1) SO3 + 2KOH = K2SO4 + H2O (when sulfur (VI) oxide interacts with potassium hydroxide, potassium sulfate and water are formed);

2) SO3 + H2O = H2SO4 (when sulfur (VI) oxide interacts with water, sulfuric acid is formed);

3) SO3 + Mg (OH) 2 = MgSO4 + H2O (when sulfur (VI) oxide interacts with magnesium hydroxide, magnesium sulfate and water are formed).
