Metal 'B' is attracted by magnet. For example, it reacts with warm dilute hydrochloric acid to give Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do. It lies in the middle of the reactivity series.Because of lesser reactivity, the reaction of Al with acid is not so vigorous as compared to the most reactive metals in series. A X → Y → Z B X → Z → Y C Z → X → Y D Z → Y → X 26 Which property is shown by all metals? When a metal reacts with an acid, a salt and hydrogen are produced.
