Homework Answers
So rate of polymerization is continuosly changing whenever a new styrene molecule copolymerised with methyl methacrylate.
Mechanism can be performed via free radical or anionic mechanism.
Large number of polymers are produced at the end of reaction
which could be easily identified by repeating units in the
chain.

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...

From problem 9.10 in the book. An initial experiment at an eyeglass manufacturer has produced poly(methyl methacrylate), whose monomer is (used in eyeglasses and hard contact lenses) with a number average molecular weight of 143,000, by carrying out the reaction at 65 °C for 45 minutes. Since the product design group has determined that a molecular weight of 100,000 is satisfactory, how fast can you speed up the production process and still achieve the desired MW? The activation energies for...

First, think about how much McDonaldization you think is present in your life, providing some examples. Then, consider whether you would like this to change, by reflecting on the positive and negative consequences of McDonaldization for you, including a consideration of our core value of community. You may want to focus on only one or two changes.Finally, think about how you might go about implementing such change(s), also thinking how that might relate to the core value of community.

Using Feldman’s three-stage model of organizational socialization (anticipatory socialization, encounter, and change and acquisition), how would you describe the way you were socialized into an organization where you have worked? How well does the model fit your experience? Having read about the model, what recommendations would you offer?

my question is how to identify a priority.
Is it by atomic mass? How does the methyl group attached to the
lowest priority affect both? what would be the numbered priority
for both of these ?
for the first picture I know F is the priority and for the
second picture I know Br would be the priority number one (for the
top chiro center) although I’m not sure which one would be number
two since it is attached to...

In your own words describe how do you feel about April's post below; At this stage of my venture in fayVen, I’m not certain that I am ready for either an angel investor or a venture capitalist (VC). Currently, I need about $10,000 – 20,000 to get fayVen to the minimum viable product (MVP) stage. I wouldn’t want to waste an opportunity, if I had an audience of angel investors and or venture capitalists, with such a small amount needed....
