Dacron
Here are the solutions to the questions:
84. Which one of the following is not formed by addition polymerization?
- Addition polymerization involves monomers adding to one another without the loss of any atoms. Polyethylene, polyvinyl chloride, and Teflon are all formed by addition polymerization.
- Dacron is a polyester, which is formed by condensation polymerization. In condensation polymerization, monomers join together with the elimination of a small molecule, such as water.
The correct answer is D) Dacron.
85. How does increasing the pressure increase the rate of a chemical reaction?
- According to collision theory, for a reaction to occur, reactant particles must collide with sufficient energy and correct orientation.
- For gaseous reactions
