Answer : The correct statements are,

The chemical formula for ammonium hypochlorite is $NH_4ClO$ .

The chemical formula for ammonium nitrate is $NH_4NO_3$ .

The chemical formula for ammonium sulfate is $(NH_4)_2SO_3$ .

Explanation :

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

(1) The chemical formula for ammonium carbonate is $(NH_4)_2CO_3$ .

This formula is formed when the 2 ammonium ion combine with 1 carbonate ion.

(2) The chemical formula for ammonium hypochlorite is $NH_4ClO$ .

This formula is formed when the 1 ammonium ion combine with 1 chloride ion and 1 oxide ion.

(3) The chemical formula for ammonium nitrate is $NH_4NO_3$ .

This formula is formed when the 1 ammonium ion combine with 1 nitrate ion.

(4) The chemical formula for ammonium phosphate is $(NH_4)_3PO_4$ .

This formula is formed when the 3 ammonium ion combine with 1 phosphate ion.

(5) The chemical formula for ammonium sulfate is $(NH_4)_2SO_3$ .

This formula is formed when the 2 ammonium ion combine with 1 sulfate ion.

Answer : The correct statements are,

The chemical formula for ammonium hypochlorite is $NH_4ClO$ .

The chemical formula for ammonium nitrate is $NH_4NO_3$

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

(1) The chemical formula for ammonium carbonate.

The given compound ammonium carbonate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and carbonate ion $(CO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium carbonate is $(NH_4)_2CO_3$ .

(2) The chemical formula for ammonium hypochlorite.

The given compound ammonium hypochlorite is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and hypochlorite ion $(ClO^{-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium hypochlorite is $NH_4ClO$ .

(3) The chemical formula for ammonium nitrate.

The given compound ammonium nitrate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and nitrate ion $(NO_3^{-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium nitrate is $NH_4NO_3$ .

(4) The chemical formula for ammonium phosphate.

The given compound ammonium phosphate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and phosphate ion $(PO_4^{3-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium phosphate is $(NH_4)_3PO_4$ .

(5) The chemical formula for ammonium sulfate.

The given compound ammonium sulfate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and sulfate ion $(SO_4^{2-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium sulfate is $(NH_4)_2SO_4$ .
