b) Oxygen , sulphur, carbon, phosphorus etc.

3. a) Lead, gold, silver etc.

4. Metals: Metals are hard, lustrous, malleable, ductile, sonorous and good conductors of heat and electricity.

Non-metals: Non-metals are not hard, not lustrous, not malleable, not ductile, not sonorous and are not good conductors of heat and electricity.

5. (sorry, dont know)

6. Phosphorus is stored in water because it is a very reactive non-metal. It catches fire if exposed to air.

7. Potassium and sodium are very reactive. It reacts vigorously with oxygen and water. A lot of heat is generated in the reaction. It is, therefore, stored in Kerosene.

8. (Sorry, dont know)

9. Displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound.

10. This is because zinc is more reactive than copper. A more reactive metal can replace one less reactive metal, but a less reactive metal cannot replace a more reactive metal.

Sorry for the answers which I dont know... But you can find them on google.
