nh₄no₃
nano₃
nano₂
ca(no₂)₂
fecro₄

Explanation:

• For \(NH_4NO_3\): The compound consists of ammonium (\(NH_4^+\)) and nitrate (\(NO_3^-\)) ions. So it is named ammonium nitrate.
• For \(Ca(NO_2)_2\): It has calcium (\(Ca^{2+}\)) and nitrite (\(NO_2^-\)) ions. Thus, it is calcium nitrite.
• For \(FeCrO_4\): Iron (\(Fe\)) has a +2 oxidation state here (as \(CrO_4^{2 -}\) is chromate ion), so it is iron(II) chromate.

Answer:

Ammonium nitrate, Calcium nitrite, Iron(II) chromate
