• ki
• fe2o3
• (nh4)3po4

Answer :

The name of compound is, potassium iodide.

The name of compound is, iron (III) oxide.

Explanation :

Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.

The rules of ionic compounds is given by:

(1) The given compound is an ionic compound. It is made up of two different ions which are potassium ion and iodide ion .

So, the name of is, potassium iodide.

(2) The given compound is an ionic compound. It is made up of two different ions which are iron ion and oxide ion .  In this an oxidation state of iron is (+3).

So, the name of is, iron (III) oxide.

(3) The given compound is an ionic compound. It is made up of two different ions which are ammonium ion and phosphate ion .

So, the name of is, ammonium phosphate.

what is the question here. i think you messed up.
