RMS end to end distance I0 = a.r1/2
I0 = RMS end to end distance
a = chain length =0.2 nm
r = number of repeated units =10,000
RMS end to end distance I0 = 0.2 x (10000)1/2 = 0.2 x 100 = 20 nm

. Consider a flexible (random-walk) polymer description of a protein in its denatured state. The protein chain consists of 300 amino-acids, and the separation between the C atoms of each amino-acid is 0.36 nm. The statistical segment length of an unfolded protein contains about 6 amino-acids. (a) How many statistically independent segments are there in this unfolded protein chain? (b) What is the size (root-mean-square end-to-end distance) of the unfolded protein? (c) What is its entropic spring constant?
. Consider...
3. [5] Retinal consists of a chain of carbon atoms roughly 1.5 nm long. Electrons in this long chain molecule behave very much like particles in a box The retinal molecule is a linear molecule that has 12 electrons that are free to move about the chain According to the Pauli exclusion principle, when this molecule is in its ground state, these 12 electrons fill the first 6 states of the box. Thus, the lowest energy photon that can be...
2. Microcanonical ensemble: One-dimensional chain. (24 pts.) Consider a one-dimensional chain consisting of N segments as illus- trated in Figure 1. Let the length of each segment be a when the long dimension of the segment is parallel to the chain and 0 when the long dimension is normal to the chain direction. Each segment has just two non-degenerate states: long dimension parallel to the chain or perpen- dicular to the chain. Now consider a macrostate of the chain in...

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 linear chains? d. What is fivg, the average number...
Use the following table to answer Question 2. Market research estimates the maximum value for each of two goods by three customer types (segments). These values are the entries in the table. Assume that the cost of production is zero and the seller need only maximize revenue. Assume further that each consumer will purchase each good as long as the price is less than or equal to his/her valuation. You are hired to evaluate the pricing options available to the...
please only do H-M. i have done everything else.
