### Step-by-Step Solution for the Extraction of Mercury from Cinnabar (HgS) 1. **Identify the Ore**: The ore of mercury is known as cinnabar, which has the chemical formula HgS (mercury sulfide). **Hint**: Remember that cinnabar is a sulfide ore, which means it contains sulfur along with mercury. 2. **Roasting Process**: The first step in the extraction process is roasting. During roasting, cinnabar (HgS) is heated in the presence of oxygen. This process converts the sulfide ore into an oxide ore. ...
