Answer:
When cinnabar,a ore of mercury, is heated in air, it is first oxidised and converted into mercuric oxide (HgO). Mercuric oxide on further heating is then reduced to mercury . The following are the equations which take place.
2HgS(s) + 3O2(g) -Heat → 2HgO(s) + 2SO2(g)
2HgO(s) Heat → 2Hg(l) + O2(g).
