three chemical questions

by

1) Draw the appropriate structure of Chlorine pentafluoride (ClF5) including any lone pairs.

2) Nitrate Anion (NO3-): Draw all resonance forms and indicate the formal charges on each atom. Show how you calculated the formal charges. What is the hybridization of each atom?

3) Based off molecular polarity determined by VSEPR theory, would the following compounds: CO2, NH3, XeF4, BCl3 be soluble in CCl4 or H2O Explain your reasoning. If explaining with a drawing is easier, be sure to make clear indicators as to why you are identifying each compound as polar or nonpolar.
