(a)
Interpretation:
From the given data, the length in centimeters (cm) of human chromosome 11 has to be calculated.
Concept Introduction:
Chromosomes:
The double helix structures of copied DNAs get coiled to save space. Such coiled forms of DNA organize and protect the genetic information. This complete set of genetic information is packaged into chromosomes which are rod-shaped. So, a compact package of coiled DNAs is known chromosome which lies in the nucleus of cells.
(b)
Interpretation:
From the given data, the factor by which the DNA is condensed further has to be found.
Concept Introduction:
DNA:
DNA is a self-replicating genetic material that is present in all living organisms. It carries genetic information from one generation to the several successive generations which brings several physical traits in an individual as a sign of resemblance from his/her parents and ancestors. Those traits are the uniqueness to the individual.
(c)
Interpretation:
A reason for why the level of compaction of DNA in chromosome as discussed in sub-part (b) is necessary has to be suggested.

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
