(a)
Interpretation:
The hydrophobic and hydrophilic part of the 7, 10, 13, 16, 19-docosapentaenoic acid should be labeled.
Concept Introduction:
Fatty acids are long chain
Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(b)
Interpretation:
The melting point difference in the cis and trans-isomer of the 7, 10, 13, 16, 19-docosapentaenoic acid should be determined.
Concept Introduction:
Fatty acids are long chain carboxylic acid, which may or may not have unsaturation in the molecule. They react with glycerol to form triglycerides. The reaction is known as esterification as a carboxylic acid group reacts with the alcoholic group to form an ester group.
Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(c)
Interpretation:
The physical state of 7, 10, 13, 16, 19-docosapentaenoic acid as solid or liquid at room temperature should be determined.

Unsaturated fatty acids can be defined as the long chain fatty acids which have a long hydrocarbon chain with −COOH group. In unsaturated fatty acids, the carbon chain must have at least one double bond.
(d)
Interpretation:
The omega-n designation for the 7, 10, 13, 16, 19-docosapentaenoic acid should be determined.

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
