13. (4) MgS and NaCl have different lattice energies. A. Which compound has the largest lattice...
M Review | Constants 1 Periodic The lattice energies of NaCl and KF are given in the table in the introduction. Based on the lattice energies, would you expect the Na - Cl or the K - F distance to be longer? Match the words in the left column to the appropriate blanks in the sentences on the right. Reset Help smaller NaCl Lattice energy is inversely proportional to the distance between two ions in an ionic compound; therefore, the...

Which of the following solids is likely to have the largest exothermic lattice energy? a. LiF b. NaCl c. AlCl3 d. Al2O3 e. CaCl2
For each pair, indicate which would have the lattice energy of greater magnitude. O Mgs o Сате • Cao O sro o Cao O Cas O CSF ORDF OKI O sro Consider how the relative energies of interaction of "point" charges would vary with respect to the expected interionic distances, according to Coulomb's Law. (Detailed calculations should NOT be required to make these comparisons -- but consider, for example, the relative effects of doubling the charges, as compared to increasing...

2. Why do ionic substances with higher lattice energies tend to be less soluble in water than substances with lower lattice energies? 3. Which would you expect to have the larger hydration energy, SO or CIOA? Explain. 4. Ethyl alcohol, CH CH2OH, is miscible with water at 20°C, but pentyl alcohol, CH3CH2CH2CH2CH2OH, is soluble in water only to the extent of 2.7 g/100 ml. Explain.
Part II: lonic Bonds Earlier in the semester you used solubility rules to Now you can explore why NaOH is soluble and all Lattice Energy bility rules to decide it a substance would dissolve in solution soluble and Al(OH)) is insoluble. The key to this concept is parate a mole of a solid into its gaseous ions. lue of AH for the following reaction. e stability of the ionic solid. The higher the lattice Lattice Energy - the enthalpy required...
The AH soln for NaCl is different than for LiCl. The reference table shows, lon lonic Radius 76 pm Nat 102 pm a) Write the complete electron configuration of Nat. b) Explain why Nat has a bigger ion size than Lit. c) Lattice energy is related to the amount of energy associated with the dissociation of solid crystal into gaseous ions. Which salt has the higher Lattice Energy?
Which one of the following aqueous solutions would you expect to have the largest conductance: (a) 0.050 M NaCl, (b) 0.050 M Na2SO4, or (c) 0.050 M Na3PO4? Explain your reasoning.
