Consider the hydration reactions that take place between the substances given to us and water:
Barium oxide and water react to form barium hydroxide.
BaO + H2O = Ba (OH) 2
Lithium oxide and water actively react to form lithium hydroxide.
Li2O + H2O = 2LiOH
The acidic sulfur oxide is hexavalent and water forms sulfuric acid.
SO3 + H2O = H2SO4
Calcium oxide and water, calcium hydroxide is formed (lime slaking reaction).
CaO + H2O = Ca (OH) 2
The reaction takes place between pentavalent phosphorus oxide and water resulting in the formation of phosphoric acid.
P2O5 + 2 H2O = 2 H3PO4
Sodium oxide reacts with water to form sodium hydroxide.
Na2O + H2O = 2 NaOH
Sevalent manganese oxide with water forms the substance permanganate.
Mn2O7 + H2O = 2 HMnO4.
