Do mixed ionic compounds or mixed covalent compounds use the prefixes?
Example : Which of the following is a mixed covalent compound?
A) dinitrogen trioxide
Or
B) iron oxide
I don't remember which of them uses the prefixes at the beginnings of each compound.
Thank you. Xx

The naming of compounds has NOTHING to do with any "ionic" or "covalent" classification. Compounds of a metal and a nonmetal use the Stock system. Compounds of two nonmetals use the Greek prefixes.
N2O3 is named dinitrogen trioxide because it contains two nonmetals, not because the bonds have high covalent character.
FeO or Fe2O3 is named either iron(II) oxide or iron(III) oxide because it contains a metal and a nonmetal, not because of some supposed "ionic" bond. In FeO, the bonds have 48% ionic character. Neither FeO, nor Fe2O3, can be called simply "iron oxide". That's the point of the Stock system. You must include a Roman numeral to indicate the oxidation state of the metal.
