2) they are very reactive metals. they are kept in kerosene to prevent them from coming in contact with oxygen and moisture.

3)This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide. This oxide layer is very stable and prevents further reaction of aluminium with oxygen.

4)Carbonates and sulphide ore are usually converted into oxides during the process of extraction because it is easy to extract metal from its oxide ore by reduction reaction when compared to carbonate or sulphide ore. Obtaining a metal from its oxide is much easier than doing that from a metal sulphide and carbonate
