Zinc-deficient animals require 50% more food to gain the same weight of an animal supplied with adequate amounts of zinc. While zinc had been previously isolated in other parts of the world, his detailed description helped zinc become commercially available throughout Europe. Studies of the metal's behavior in relation to hydrogen chloride dissolved in various organic liquids revealed that hydrogen chloride solution in anhydrous benzene reacts vigorously with zinc, but the reaction halts as soon as the surface is covered with a film of solid zinc chloride, which dissolves poorly in benzene. Additionally, zinc reacts with halogens, oxygen, chalcogens, alkalis, acids, ammonia and ammonium salts, and even with less active metals. The metal received its modern name in the 20th century. Zinc was later discovered in Europe and was soon introduced for widespread use in various spheres. As many as 2 billion zinc-core pennies are circulating in the U.S. economy.
