Please
help me with this Python program.
Write a program that takes the plastic identification number from the user and returns information. The program should allow the user to continue using the program until they quit. It should also validate the input and only accept the integers 1-7 as input. All code should be in a function. I suggest the following function structure: printWelcome - prints program information validateUserinput1 to7 - takes user input, validates, and returns valid input main...
Of the five chemical types of recyclable plastics on the previous page, which should give the simplest infrared spectrum, and why? 3. What is the "fingerprint" region of the infrared spectrum and why is it called this? 4. 5. If an infrared spectrum displayed a deep, broad absorbance at about 3400 cm', what groups could this be attributed to? 6. If a sample contained an aromatic ring, what evidence would you expect to see in its spectrum? We will use...
please answer all questions
1. (2) Give the structure of the monomer that would be used to produce each of the following polymers. -CH2-CH-CH2-CH-CH2-CH -CH2-CH-CH2-CH-CH2-CH- Ci Ci Ci CH3 CH3 CH3 2. (5) Where are you most likely to find each of the following polymers in your everyday life: polyethylene terephthalate (PET) high-density polyethylene (HDPE) polypropylene (PP) polyvinyl chloride (PVC) polystyrene 3. (1) Polyester is an example of an addition or a condensation polymer? 4. (1) What must be done...
please only do H-M. i have done everything else.
2. During the acid catalyzed polymerization of terephthalic acid and ethylene glycol, some fraction of methanol (CH-OH) is incorporated, but no more ester bonds can be formed. a. Based on the above, what is the extent of reaction, p? b. How does fav determine whether a linear or network polymer is formed as p nears 1? c. Why do you believe the polymer in this reaction will be a gel-network or...
I need help with the last question #7. Please
help!
Preaboratory Assignment-Introduction to IR Spectroscopy Make use of the index in your textbook for information on the polymers' structures From the formulac in your text, draw the structure of the repeating groups of (a) polypropylene and (b) poly(cthylene glycol terephthalate): 1. 2. What atom is present in PVC that is different from the other examples of polymers in the text? (Note that the text index shows PVC under "vinyl chloride.")...
Discuss the purpose of the reaction. Discuss the function of the
reagents used and what you are monitoring in that reaction.
JVCUDDL/64/1/649?response-content-dispositioninline Introduction: It is estimated that approximately 150 million metric tons of plastics are currently circulating in our global system of oceans and waterways. This seems like a fairly generic "big! number", and it's difficult to understand the scale of the problem without converting it to something more relatable. A standard empty plastic water bottle weighs approximately 12.7 g....
can
someone help me find this information?
Pre-Laboratory Exercise: Plastics Identification I. List four properties that you will use in lab to determine the identity of the polymer samples 2. Describe the density test. What observation will help you determine the density of each polymer? What precautions should be taken in placing the sample in the solutions? 3. Write the name and abbreviation for the six recyclable polymers 2 huetn deisity polyetayene.HDpz poulene: PP 4. Given the list of wavenumber...
Evaluate and investigate the
following IR Spectrum, 13C NMR Spectrum
and 1H NMR Spectrum. Identify
the most important peaks and correlate the
results as much as you can from the obtained product in
the multi-step synthesis of ethyl acetoacetate.
This is Product E from this multi-step synthesis
where Product C was identified as in the figure
below and as such, identify what product can be obtained
after the synthesis from the spectra provided. Use the template
below in analysing the...

TrueGrid manufactures the world’s strongest permeable paver. It’s a 100% permeable, which is an alternative to concrete and asphalt. It is permeable solution that allows the water to permeate through the surface and be detained below. It’s able to handle high traffic and heavy loads, so it can go from your drive way all the way to your high traffic 18 wheeler parking lots and everything in between. TrueGrid helps prevent flooding because the biggest reason is there is no...
