Chapter 10

Question 1

Polymer

Answer 1

Made up of several hundred or thousand monomers to create a polymer molecule

Question 2

Monomer

Answer 2

A small molecule that has functional groups that allow multiple reactions that link the units

Question 3

Naturally occurring polymers

Answer 3

Example: start, cotton, wood, silk, proteins, nucleic acid’s, etc.

Question 4

Polyethylene

Answer 4

The simplest and least synthetic polymer. It can be found in plastic. It is Etheline linked to itself multiple times. CH 2 = CH 2+ CH 2 = CH 2+ CH 2 = CH 2+…—> CH2CH2CH2CH2CH2

Question 5

Vulcanization

Answer 5

Sulfur atoms cross-link the hydrogen chains, putting them side to side

Question 6

Cross – linking

Answer 6

Putting the hydrocarbon chains side to side to create a stronger molecule. Think of rubber at its original state, and then of it is a tire. What changed?

Question 7

Silicone

Answer 7

A polymer that is not a carbon chain. It is made up of silicon and oxygen atoms. They can be oil‘s, greases, rubbery compounds, or solid resins depending on how long the chain is.

Question 8

What are some environmental problems with plastic?

Answer 8

Think about it.
