(a)
Interpretation:
The formula for barium chloride should be written along with identify whether it is soluble in water or not.
Concept introduction:
First, the symbol of the metal (cation) with its ion charge as a superscript should be written.
The symbol of the non-metal (anion) with its ion charge or polyatomic ion as a superscript should be written.
After that, the charges should be criss cross so that they become subscript for the opposite element and + and - charges should be removed.
Solubility of any compound is predicted by above solubility chart.
Blank boxes indicate no precipitate formation occurs which means soluble in dilute solution.
Boxes with grey small box will form precipitate from dilute solutions and boxes where formula is written this is a cation-anion combination that will form precipitate.
(b)
Interpretation:
The formula for magnesium hydroxide should be written along with identify whether it is soluble in water or not.
Concept introduction:
First, the symbol of the metal (cation) with its ion charge as a superscript should be written.
The symbol of the non-metal (anion) with its ion charge or polyatomic ion as a superscript should be written.

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.
