A. Calculate the lattice energy of NaI(s) using the following thermodynamic data (all data is in kJ/mol). Note that the data given has been perturbed, so looking up the answer is probably not a good idea. Na(s) ΔHsublimation = 88 kJ/mol
Na(g) Ionization energy = 476 kJ/mol
I-I(g) Bond energy = 131 kJ/mol
I(g) Electron affinity = -315 kJ/mol
NaI(s) ΔH°f = -308 kJ/mol
kJ/mol
Do you expect this value to be larger or smaller than the lattice energy of TlCl(s)? largersmaller
B. Calculate the lattice energy of InBr(s) using the following thermodynamic data (all data is in kJ/mol). Note that the data given has been perturbed, so looking up the answer is probably not a good idea.
In(s) ΔHsublimation = 223 kJ/mol
In(g) Ionization energy = 538 kJ/mol
Br-Br(g) Bond energy = 173 kJ/mol
Br(g) Electron affinity = -345 kJ/mol
InBr(s) ΔH°f = -195 kJ/mol
kJ/mol
Do you expect this value to be larger or smaller than the lattice energy of InCl(s)? largersmaller

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
