Interpretation: The steps used to form a ceramic material from scandium and ethanol using sol-gel process has to be explained.
Concept Introduction:
Ceramics are polymeric inorganic solid compounds consists of non-metal, metalloid or metal atoms held together by covalent and ionic bonds. When an inorganic substance is melted and solidified, it results in ceramics.
Ceramics are hard and have high melting points. They are heat insulators.
Ceramics have crystalline or amorphous structure.
Example: Glass
A process called sintering is to prepare ceramics. The resulting product was irregular in shape with cracks, spaces and imperfections. Hence, sol-gel method was employed to prepare ceramics of uniform size without much of cracks and gaps.

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.
