Chem 167 SI Wednesday 10-17-12 1) What type of hybridization does each carbon atom have in C2H3O? Which type and how many of each bond type are present? 2) What is the shape of the NH3 molecule? 3) Is NH3 polar or nonpolar? 4) Is CCl4 polar or nonpolar? Draw a picture of the molecule and label partial charges. 5) Why are MSNs such great vessels for cancer drug delivery? There are three reasons. 6) In this general phase diagram (drawn on board) label the sections of liquid, solid, and vapor. 7) Recreate the phase diagram for carbon without your notes. Remember to label the two sections of the solid phase of carbon. 8) There are three types of solid carbon. What are these, what type of hybridization does each have, what are common examples of each? 9) In general what two types of solids exist? How can each be described?
