Title: Chemical reaction of mercuric oxide upon heating
Caption: Although mercuric oxide (a red solid) has none of the properties of mercury (a silver liquid) or oxygen (a colorless gas), when 100.00 g of mercuric oxide is decomposed by heating, the products are 92.61 g of mercury and 7.39 g of oxygen. Properties are completely changed in this reaction, but there is no change in mass.
Keywords: chemical reaction, mercuric oxide, mercury, oxygen
