)compare the mass of pet you used in this experiment to the amount of terephthalic acid monomer you obtainedby answering the following questions.(a) approximate the mass of terephthalic acidone would obtain if the depolymerization proceeded to completion. b) based on your answerto part (a) and the amount of terephthalic acidyou actuallyobtained, would you consider the depolymerization of pet (using the protocol you employed) an efficient process? explain your rationaleand be sure to account for any impurities observed by 1hnmr. c)provide a suggestion on how you might modify this experimental procedure to further improve the efficiency of the pet depolymerization reaction.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
