right on the hydronitric acid.
right on sodium chlorate

wrong on the others.
What does Iron(III) mean? does it mean Fe⁺³?
what is a tetrachloride?
what is ammonium?
on the last, you have to put in the II or III on the iron, and it is a sulfide, not sulfate. You need to memorize the polyatomic ions.
