WebCinnabar is heated in air. When cinnabar is burned in air, it is converted to mercuric oxide, which produces sulfur dioxide gas. The balanced equation is as follows: 2 HgS s + 3 O 2 … WebThe oxides of such metals can be reduced to metals by heating alone, one example is mercury. Mercury is usually found in ores such as cinnabar (HgS). Cinnabar (HgS) when heated in air turns HgS into HgO (mercury oxide) accompanied by liberation of sulphur dioxide. 2HgS+3O 2→2HgO+2SO 2.
