Answer 2

Explanation:

• iron oxide is basic.
• because it gives salt and water on reacting with acids like sulphuric acid, hydrochloric acid etc.
• depending on the electropositivity of central atom,we can decide whether the oxide is acidic or basic. more the electropositivity of central atom,more the basic nature of oxide.
• more the electronegativity of central metal atom,more is the acidity.
• many metals have oxides which are basic in nature.
• examples: sodium oxide, magnesium oxide, copper(II)oxide,Bi2O3 etc
