The plastic known as PETE (polyethyleneterephthalate) is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. PETE is a polymer of terephthalic acid and ethylene glycol. Today, PETE is the most widely recycled of all the plastics. After it is separated from other plastics, PETE can be used in polyester fabric, door mats, and tennis ball containers. In 2015, 1.84×109 lb1.84×109 lb of PETE bottles were recycled in the U.S. The density of PETE is 1.38 g/mLg/mL.
If 2.74×109 kg2.74×109 kg of PETE bottles were sold in 2015, what percentage of those bottles were recycled?
Express your answer to three significant figures.

How does the structure account for different behaviour and nature, hence the use of a polymer?arrow_forwardPTT (polytrimethylene terephthalate) is a polyester formed from 1,3-propanediol (HOCH 2CH 2CH 2OH) by the given reaction. PTT is sold under the trade name Sorona by DuPont. 1,3-Propanediol can now be made from a plant source like corn, rather than from petroleum starting materials. This makes PTT a more environmentally friendly polyester than PET. What is the structure of PTT?arrow_forward

Cellulose acetate is spun into yarn by dissolving it in acetone or methylene chloride and forcing the solution through spinnerets into warm air, where the solvent evaporates. An organic chemistry student wore a long-sleeved acetate blouse to the laboratory. She was rinsing a warm separatory funnel with acetone when the pressure rose and blew out the stopper. Her right arm was drenched with acetone, but she was unconcerned because acetone is not very toxic. About ten minutes later, the right arm of the student’s blouse disintegrated into a pile of white fluff, leaving her with a ragged short sleeve and the tatters of a cuff remaining around her wrist. Explain how a substance as innocuous as acetone ruined the student’s blouse.arrow_forward
