Answer 1

$\huge\sf\underline{Answer♡࿐}:$

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.

Cinnabar is the sulphide ore of mercury from which the mercury metal is extracted bye the processes of roasting and reduction. The sulphide or is heated in the presence of oxygen to convert it into oxide ore then further reduction gives the mercury metal and oxygen gas.

The sulphide or is heated in the presence of oxygen to convert it into oxide ore then further reduction gives the mercury metal and oxygen gas.

Most of the world's mercury is obtained from its main ore, cinnabar or vermillion with the chemical structure mercury sulphide (HgS).
