Paper overlay C C. Zinc Blende, ZnS Use the plastic black template marked phere on a metal get the pink sphere e firmly. Note that It takes a little patience to build this structure. Rather than placing a small pink sphere on rod, you are balancing it in one of the vacancies of the lattice. Have faith, if you get the nint in the correct location it will not fall out, the colorless spheres will hold it in place firmly. N you are using the same template and base as you did for NaCl. 1. If the sulfide ions are on the lattice points of a face-centered cubic unit cell, how would describe the location of the zinc ions? 2. How many zinc cations surround each sulfide? How many sulfide ions surround each zinc cation? Does this match the empirical formula of zinc sulfide? OS 3. A certain form of silver iodide adopts the zinc blende structure. The density of the salt is 5.69 g/cmº. Calculate the length of a side of the unit cell. Calculate an approximate distance between the silver cations and iodide anions in the structure. (You can approximate the location of silver ion because it resides in a pocket 4 of the way down the body diagonal.)
