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...

Critical Thinking Questions: 2) The polymerization of ethylene ("monomer") with a radical initiator follows the same chain reaction. Please write the mechanism (all arrows) from ethylene (==ethene) to polyethylene). Start with an initiator of R-R. After breaking the initiator bond to your radicals, use either radical for your 1"' reaction with ethylene. Indicate repeating reactions by multiple arrows. Write the final product in a common short...

A. This addition polymer features aromatic rings and is commonly found in moisture-barrier wraps used in home construction B. This condensation polymer is the product of a difunctional acid with aromatic character and the type of glycol one would find in antifreeze solutions and is used to make countless beverage containers annually. C. This addition polymer is completely halogenated and is associated with non-stick working surfaces in the kitchen and in industry. D. This condensation polymer is the product of...
