)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.

Which step in naming unsaturated hydrocarbons is used for alkenes but not alkynes

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

In which phase(s) do the molecules take the shape of the container?
