CHEM 3050 Study Guide - Final Guide: Polyethylene Terephthalate, Waste Hierarchy, Low-Density Polyethylene
Document Summary
9 & 10 chemistry study guide exam 3. Ch305 exam 3 things to know: chapter 9&10 only. A few ideas from the last exam may carry through, and some concepts from ch304k of course. Again, this might not cover absolutely everything, but it gives you a good starting point. Know all the functional groups given in ch 9 and in ch. 10. Be able to spot them in a structure. Chapter 9: the world of polymers and plastics. Polymers are everywhere! are natural and synthetic are made from non-renewable and (now sometimes) renewable materials. Most polymers (cds, dvds, plastic case around cell phone/pencil, calculator, computer) come from a single raw material: petroleum (main feedstock for polymers) Petroleum: non-renewable resource 3% of petroleum is used as a raw material (some of this is for pharmaceuticals) Polymers can be made from any carbon-containing starting material (crude oil) Renewable resources to form polymers: materials such as wood, cotton fibers, straw, starch.
