Dacron polyester and nylon 6,10 are called copolymers because dacron polyester and nylon 6,10 are called copolymers because the monomer units will only react in the presence of some other molecule, a cooperating molecule. each monomer unit is chemically unreactive. when used as fibers they are always combined with some other fiber. they are produced from chemical reactions between two different monomers. none of these explanations is correct.

Why are gamma rays not affected by a magnet as they pass over it? gamma rays are composed of only energy. gamma rays do not have enough mass to be affected. gamma rays do not have the right electrical charge to be affected. gamma rays move too fast for anything to affect their pathway.

Why do sodium and neon have vastly different chemical and physical properties despite having similar atomic masses?

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
