The colour of silver nitrate solution changes when a copper rod is dipped in it. Explain with the help of the chemical reaction involved.

What happens when a metal placed above hydrogen in the reactivity series reacts with dilute acid? Explain this with the help of an example.

Differentiate between metal oxide and non-metal oxide.

Differentiate between the malleability and ductility.

What are alloys? Why do they find immense application as compared to metals?

Give a reason: Aluminium is used for making electrical wires.

Give reason: Cooking utensils are made of metals but their handles are made of wood or plastic.

Compare the chemical properties of metals and non-metals.

The table given below shows the reactions of metals with solutions of metal salts
