Metal A burns in air, on heating, to form an oxide `A_(2)O_(3)` whereas another metal B burns in air only on strong beating to form an oxide BO. The two oxides `A_(2)O_(3)` and `BO` can react with hydrochloric acid as well as sodium hydroxide solution to form the corresponding salts and water.
(a). What is the nature of oxide `A_(2)O_(3)`?
(b). What is the nature of oxide `BO`?
(c). Name one metal like A.
(d). Name one etal like B.
