Question

6 A polymer is really just A a collection molecules all linked together in a big crosslinked network B a linear macromolecule made from lots of monomers all linked together C a collection of molecules that associate strongly through hydrophobic, ionic or hydrogen bonds D a highly branched giant molecule with lots of branch points and arms 7 A monomer is A B C D the basic unit of a polymer, linked up through ionic interactions what becomes the repeat unit of its polymer what's used to make a polymer chemically bonded to two other monomers on either side up and down the polymer chain 8 Polyethylene is the cheapest polymer made, used in garbage bags and bullet proof vests A True B False 9 Wood and cotten are mostly made of A a polysaccharide called "cellulose" B polyisopene C amino acids in the form of polypeptides D glucose monomers linked up in a polymer 10 Polymer science is the study of giant molecules, both natural and synthetic A True B False

Explanation / Answer

6 ) Polymer is a linear macromolecule

7) Monomer is a unit used to make a polymer. a lots of single monomers linked together will give a polymer

8) polyethylene is not the cheapest. It is expensive than polypropylene.

9) Cotton is made of cellulose -   Cellulose is a macromolecule –– a polymer made up of a long chain of glucose molecules.

10) true
