Exercise L39 part b
Hi! In part b of problem L39, it asks for the name of the oxide with the empirical formula (spoiler alert) SnO2. I'm a little unclear on how to find the proper name for it (tin (IV) oxide in the solutions manual, due to the +4 charge on Sn). Why, however, wouldn't tin dioxide be appropriate? Thank you so much!

Re: Exercise L39 part b
SnO2 is an ionic compound so you would use the procedure to write the name for ionic compounds (metal + nonmetal), which is:
1. Determine the charge on the cation (Sn = +4) and anion (O = -2).
2. Name the cation. If it is a transition metal, put its charge in parentheses. For this example, you would write "tin (IV)."
3. Then add the name of the anion ("oxide").
The name "tin dioxide" is not correct because that is using the naming system for molecular compounds (nonmetal + nonmetal), like CO2 (carbon dioxide).
Hope this helps!
