The compounds Na2O, CdS, and ZrI4 all can be described as cubic closest packed anions with the cations in tetrahedral holes. What fraction of the tetrahedral holes is occupied for each case?
Answer to relevant QuestionsThe structure of manganese fluoride can be described as a simple cubic array of manganese ions with fluoride ions at the center of each edge of the cubic unit cell. What is the charge of the manganese ions in this compound? MnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47 × 10–8 cm, and the density of MnO is 5.28 g/cm3. a. Does MnO crystallize in the NaCl type or the CsCl type ...Define each of the following. a. Evaporation b. Condensation c. Sublimation d. Boiling e. Melting f. Enthalpy of vaporization g. Enthalpy of fusion h. Heating curve Plot the following data, and from the graph determine ΔHvap for magnesium and lithium. In which metal is the bonding stronger? In regions with dry climates, evaporative coolers are used to cool air. A typical electric air conditioner is rated at 1.00 × 104 Btu/ h (1 Btu, or British thermal unit, equals the amount of energy needed to raise the ...
