Answer 1

Answer:

metallic mercury and not its oxideny electrons are required to discharge 3 moles of Ca++ iondoes the roasting of cinnabar (Hgs), produce of cinnabar (Hgs), produce

metallic mercury of cinnabar (Hgs), produce

metallic mercurySuppose you are using a meter scale (metalic) marked 0 to 100cm .Let the scale is graduated at 20°c & you are taking reading at 40°c . Let the scale becomes 101cm but you count it 100cm so measured reading is less than actual reading .
