The compound FeCl_(3) is made of three molecules of iron chloride. one atom of iron and three atoms of carbon. one atom of iron and three atoms of chlorine. two atoms of iodine.one atom of iron and one atom of carbol

The compound is made of one atom of iron and three atoms of chlorine.In the chemical formula , the "Fe" represents the element iron, and the "Cl" represents the element chlorine. The subscript "3" indicates that there are three chlorine atoms bonded to one iron atom in the compound.The other options provided are incorrect:- "three molecules of iron chloride" is not accurate, as is a single molecule, not three molecules.- "one atom of iron and three atoms of carbon" is incorrect, as there is no carbon present in the compound .- "two atoms of iodine, one atom of iron and one atom of carbon" is also incorrect, as there is no iodine or carbon in the compound .Therefore, the correct answer is that is made up of one atom of iron and three atoms of chlorine.
