Summary: Two very important products derived from air are ammonia and nitric acid. Ammonia is produced when hydrogen gas is extracted from natural gas and steam, mixed with nitrogen from the air, and heated. The resulting ammonia gas is condensed into liquid form, to be made into other chemicals. Ammonia is also used to make nitric acid, basic in the production of fertilizers, detergents, and many other...

Summary: Air, an important industrial raw material, is first filtered to remove any solid matter. Then its constituent gases-nitrogen, oxygen, and other trace gases-can be separated by compressing the air, cooling it, and then allowing it to expand, which cools it further. Since each gas liquefies at a different temperature, the gases can easily be separated. As the air expands, it is used to drive...

Summary: An explanation of the theory of infrared absorption is followed by showing a series of spectra demonstrating the major absorption peaks. Shifts within the carbonyl group, and their explanation, are discussed. The N.M.R. portion of the program covers the ideas of integration, chemical shift, and splitting in proton spectra in a logical process of development of the subject.

Summary: A fire needs heat, fuel, and oxygen. This Science Screen Report examines that triangle of ingredients, and how scientists study it in order to combat-or harness-fire. With detailed examples of firefighting techniques, the program demonstrates the removal of heat from a class A blaze through the use of water or sprayed polymers, and the elimination of oxygen, a strategy used in fighting oil...

Summary: This program, divided into three parts, looks at the difference between melting and dissolving using the example of sodium chloride. The reaction of sodium chloride solution with silver nitrate exemplifies precipitation; ammonia, added to a solution of copper (II) nitrate, forms a copper (II) hydroxide gel; and the successive complexation of copper (II) by ammonia molecules serves as an...

Summary: This program begins with an overview of the basic concepts of chemical equilibrium: reversible reactions, Le Chatelier's principle, the equilibrium law, and the calculation of K. It then analyzes how changing conditions other than temperature leads to a temporary shift in the position of equilibrium and how reactions spontaneously adjust to maintain the value of K for any given temperature....
