The plastic known as PETE (Polytethylenetetraphathalate) is used to make plastic bottles and containers for shampoo and dishwashing agents. PETE is made of terephthalic acid and ethylene glycol liquids. Today PETE is the most widely recycled plastic. In one year 1.5*109 lb of PETE is recycled. After it is separated from other plastics, PETE can be used in polyester fabrics, door mats, and tennis ball containers. The density of PETE is 1.38 g/mL.

a. Draw the line angle formula for the center formed from one molecule of terephthalic acid and one molecule of ethylene glycol.
b. Draw the line angle formula for the product formed when a second molecule of ethylene glycol reacts with the enter you draw in part a.
c. How many kilograms of PETE is recycled in one year?
d. What volume, in liters of PETE is recycled in one year?
e. Suppose a landfill holds 2.7*107L of recycled PETE. If all the PETE that is recycled in one year were placed instead in landfills, how many would fir?
Draw the condensed structural formula for a triacylglycerol that contains stearic acid and glycerol.
15.82 Identify the components (1 to 6) contained in each of the following lipids (a to d):

2. fatty acid
3. phosphate
4. amino alcohol
5. steroid nucleus
6. sphingosine
a. glycerophospholipid
b. sphingomyelin
c. aldosterone
d. linoleic acid
The insect repellant DEET is an amide that can be made from the amidification of 3-methylbenzoic acid with diethylamine.
A 6.0 can of DEET repellant contains 25% DEET.
a. Draw the line angle formula of DEET.
b. Give the molecular formula of DEET.
c. What is the molar mass of DEET?
d. How many grams of DEET in one spray can?
e. Hoe many molecules of DEET in one spray can?
