उत्तर
Na2O or MgO
Explanation:
Basic oxides are oxides of metals that react with acids to form salt and water.
From the given list, the metal oxides are Na₂O (Sodium Oxide) and MgO (Magnesium Oxide).
Na₂O (Strongly Basic): Dissolves in water to form NaOH (Sodium Hydroxide), a strong base.
\[\ce{Na2O + H2O -> 2NaOH}\]
MgO (Weakly Basic): Reacts with acids to form salt and water. It is less soluble in water but still basic.
\[\ce{MgO + 2 HCl -> MgCl2 + H2O}\]
Na₂O (Strongly basic) or MgO (Weakly basic).
