Question

a) How will you show experimentally that metals are good conductors of heat. 5 b) Describe the extraction of Mercury metal from its ore Cinnabar (HgS) for 10 class

Answer 1

Take a stand and then fix an iron rode and also put a candle on the other side and when we start heating from the one side then the candle which placed on another side of rode start melting.

When we heat cinnabar in excess air then we will get HGO + SO2 and after reduction or by displacement reaction we will get the Mercury.
