Answer 2

Answer:

zinc is more reactive than copper. Therefore, copper cannot displace zinc from its salt solution

Sodium and Potassium are highly reactive metals and react vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene

Aluminium metal has high malleability and ductility. As aluminium metal has high malleability, it can be easily transformed into very thin aluminium foils. These very thin aluminium foils are ideal for raping food. Hence, aluminium foils are used to wrap food items.
