The chemical name for Fe(NO3)2 is iron(II) nitrate.
This is a Ionic Type II metal
Correct way to name it would be:
Iron (II) Iodide or Ferrous Iodide
this is the name for the formula in chemistry of known as Iron(III) Iodide.
If you mean Fe2+ ion ... Iron (II) or Ferric ion
FeI2 is iron II iodide.
FeF3 is iron(III) fluoride.
This compound is iron(III) hydrogenphosphate.
ferrous ions and Fe3+ is ferric ion
Iron(III) carbonate or ferric carbonate.
Oxidised from Fe2+ to Fe2+
1 mole Fe2(SO4)3 = 6.022 x 1023 formula units Fe2(SO4)3 0.671mol Fe2(SO4)3 x 6.022 x 1023 formula units Fe2(SO4)3/1mol Fe2(SO4)3 = 4.04 x 1023 formula units Fe2(SO4)3
Fe2(SO4)3 is Iron (III) Sulphate.
iron fe2+
ferrous ions and Fe3+ is ferric ion
There is no compound like Fe2cl but there is Fecl2 & its common name is 'ferric chloride' .
ferrous ions and Fe3+ is ferric ion
Iron and Oxygen.
This compound is iron(III) hydrogenphosphate.
Iron(III) carbonate or ferric carbonate.
ferrous ions and Fe3+ is ferric ion
Oxidised from Fe2+ to Fe2+
first of all chromate and cloride are DIFFERENT. that being said, Fe2(CrO4)3
1 mole Fe2(SO4)3 = 6.022 x 1023 formula units Fe2(SO4)3 0.671mol Fe2(SO4)3 x 6.022 x 1023 formula units Fe2(SO4)3/1mol Fe2(SO4)3 = 4.04 x 1023 formula units Fe2(SO4)3
