Carbon and oxygen form no fewer than five different binary compounds. The mass percentages of carbon in the five compounds are as follows: A, 27.29; B, 42.88; C, 50.02; D, 52.97; and E, 65.24. Determine the empirical formulas of the five compounds.
Dragonium (Dr) is an element only found in the scales of dragons. It is known to exist only in the oxidation state of +3, and it is a metal. After dragons go for their morning swim in the Pacific Ocean, their scales change color due to the formation of a chlorine salt of dragonium which crystallizes out with four water molecules per each dragonium atom. Select the name of this compound.
