There is no absolute answer to your question because the empirical formula given will correspond to very many molecular formulas, some of which may well be good electrolytes. Also, "strong" in a chemical sense means highly ionised - with few exceptions, electrolytes are highly ionised - few compounds are one and not the other as well.

Iron oxide isn't an electrolyte.
Yes. HNO3 is an electrolyte. In water, it will dissolve into H+ ions and NO3- ions.
