Chapter 20, Problem 31CI(choose chapter or problem)
The plastic known as PETE (polyethyleneterephthalate) is a polymer of terephthalic acid and ethylene glycol. PETE is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. Today, PETE is the most widely recycled of all the plastics; in a single year, \(2.4 \times 10^{9}\) lb of PETE are recycled. After PETE is separated from other plastics, it is recycled and used to make polyester fabric, door mats, tennis ball containers, and fill for sleeping bags. The density of PETE is 1.38 g/mL. (1.7, 1.8, 1.9, 1.10, 16.3) Plastic bottles made of PETE are ready to be recycled.
a. Draw the condensed structural formula for the ester formed from one molecule of terephthalic acid and one molecule of ethylene glycol.
b. Draw the condensed structural formula for the product formed when a second molecule of ethylene glycol reacts with the ester you drew in part a.
c. How many kilograms of PETE are recycled in one year?
d. What volume, in liters, of PETE is recycled in one year?
e. Suppose a landfill holds \(2.7 \times 10^{7}\) L of recycled PETE. If all of the PETE that is recycled in a year were placed in landfills, how many would it fill?
