$\huge\underline\mathfrak\pink{♡Answer♡}$

CaO, MgO, CO2, SO3, Na2O, ZnO, Al2O3, Fe2O3.

Oxides are of three types :

• Acidic Oxides: CO2 (Carbon dioxide), SO3 (Sulfur trioxide)
• Basic Oxides: CaO (Calcium oxide), MgO (Magnesium oxide), Na2O (Sodium oxide)
• Amphoteric Oxides: ZnO (Zinc oxide), Al2O3 (Aluminium oxide), Fe2O3 (Ferric oxide)

Answer 2
