Answer 2

Answer:

Mercuric Sulphide or Cinnabar ore is generally obtained from mercury

Mercuric Sulphide is strongly heated in the presence of Oxygen (roasting) to form Mercuric Oxide. Then it is heated with limited oxygen to obtain Mercury.

Chemical Equation

2HgS + 3O₂ ------> 2HgO + 2SO₂

2HgO -----> 2Hg + O₂
