c. NO3-1 
 
 
 
 
 
 
 
d. <nowiki>SeBr</nowiki>6

Part III Give the appropriate chemical name or chemical formula for the following:

a. S4Cl9 
 
 
b. Sulfur trioxide 
 
 
c. NO2 
 
 
d. Pentafluorine monochloride 
 
 
 
Part IV Answer the following questions showing all work. 
 
a) How many grams in 23.7 liters of chlorine gas (Cl2) @ <nowiki>STP</nowiki>? 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
b) How many molecules in 24.5 grams of water? 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
c) How many f.u. do I have if I have 14.5grams of aluminum chloride, Al1Cl3 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
d) How many liters of N2 in 3.4E24 molecules of this gas. (The element N is not found alone in nature but instead as in two's so it is actually a molecule)
