Answer : The correct option is, Iron(III) phosphate, FePO_4 .

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 sulfite.

The given compound ammonium sulfate is an ionic compound. It is made up of two different ions which are ammonium ion (NH_4^+) and sulfite ion $(SO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium sulfite is (NH_4)_2SO_3 .

(2) The chemical formula for Iron(III) phosphate.

The given compound iron(III) phosphate is an ionic compound. It is made up of two different ions which are iron ion $(Fe^{3+})$ and phosphate ion $(PO_4^{3-})$ by the criss-cross method. Thus, the correct chemical formula for iron(III) phosphate is FePO_4 .

(3) The chemical formula for Lithium carbonate.

The given compound lithium carbonate is an ionic compound. It is made up of two different ions which are lithium ion (Li^+) and carbonate ion $(CO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for lithium carbonate is Li_2CO_3 .

(4) The chemical formula for Magnesium dichromate.

The given compound magnesium dichromate is an ionic compound. It is made up of two different ions which are magnesium ion $(Mg^{2+})$ and dichromate ion $(Cr_2O_7^{2-})$ by the criss-cross method. Thus, the correct chemical formula for magnesium dichromate is MgCr_2O_7 .

From this we conclude that, the correct set of chemical name and chemical formula for the same compound is Iron(III) phosphate.

Hence, the correct option is, Iron(III) phosphate, FePO_4 .

Answer from: Quest

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
