Crystal Structures Coordination Number Use the visualization tool found at https://atom.calpoly.edu/crystal/ The coordination number is the number of closest neighbors an atom has in the lattice, including atoms in the adjacent unit cells. For the following questions, you can use the Coordination mode in the visualization tool to verify your answer.
1. Determine the coordination number for the simple cubic lattice.
2. Determine the coordination number for the grey atoms in a body-centered cubic (bcc) lattice.
3. Determine the coordination number for the red atoms in a bcc lattice.
4. Explain why the coordination number for all the atoms in the bcc lattice is the same.
5. Determine the coordination number for the face-centered cubic lattice.
Which lists the 4 ions present in a dilute solution of H2SO4 in order of increasing concentration? why?
Many esters have characteristic odors (usually pleasant). Methyl salicylate (ester) can be prepared from salicyclic acid and methanol via Fischer Esterfication.
