Solution

A basic oxide--------Na₂O
A basic oxide reacts with water to give a base. This includes the oxide of most metals such as Na₂O, CaO, etc. These are basic in nature.
Example: Na₂O when reacts with cold water to produce sodium hydroxide solution and heat.
Na₂O(s) + H₂O(aq) ⇢ 2NaOH(aq) + heat
2. An oxide that dissolves in water forming an acid-----SO₂
Example: When sulphur dioxide is dissolved in water it forms sulphurous acid.
SO₂(g) + H₂O (aq)⇢ H₂SO₃(aq)
3. An amphoteric oxide-------------Al₂O₃
Aluminum oxide reacts with both acidic and basic substances to give a neutralization reaction and hence cannot be called a true acid as well as a true base.
Hence it is called amphoteric oxide.
Al₂O₃ (s)+ 6HCl (aq) ⇢ 2AlCl₃(aq) + 3H₂O(aq) (Reaction with acid)
Al₂O₃(s) + 2NaOH (aq)⇢ 2NaAlO₂(aq) + H₂O (aq) (Reaction with base)
4. A covalent oxide of a metalloid. -------SiO₂
Silicon dioxide is the main compound found in sand.
It is an example of a substance with a giant covalent structure.
It contains many silicon and oxygen atoms.
All the atoms in its structure are linked to each other by strong covalent bonds.
