Question

what is cinnabar? how is metal extracted from cinnabar? explain briefly​

Answer 1

Answer:

Cinnabar is a ore of the mercury. and mercury can be extracted by heating. the cinnabar in presence of air and by condensing the mercury the mercury vapour formed due to its low boiling point. The reaction of mercury sulphide with oxygen HgS + O2 → Hg + SO2.

Answer 2

Cinnabar also known as HgS is termed as the mercury ore.

Mercury can be obtained from cinnabar by heating the cinnabar ore in a current of air and condensing the mercury vapour formed. Due to its relatively low boiling point mercury can be easily purified by vacuum distillation. The reaction of mercury sulphide with oxygen is shown below:

HgS + O2 = Hg + SO2

This process is also called Roasting. However Mercury can be obtained from other reactions too. For ex:

HgS + Fe = Hg + FeS

4HgS + 3 CaO = 4Hg + 3CaS + CaSO4

Hope this helps...
