Chemical Formulas of the following:- Iron(II) Fluoride- Iron(II) Bromide- Iron(II) Oxide- Iron(II) Nitrate - Iron(II) Carbonate- Iron(II) Sulphate- Iron(II) Chloride- Iron(III) Oxide- Iron(III) Nitrate- Iron(III) Carbonate- Iron(III) Sulphate- Iron(III) Hydroxide
Iron is an element on the periodic table and is recognized by the symbol Fe, which is technically its chemical formula but is ussually just refered to as its symbol.
I think either concrete or vermiculite would be the best , in that order.
Iron(II) Fluoride - FeF2. Iron(II) Bromide - FeBr2 Iron(II) Oxide - FeO Iron(II) Carbonate - FeCO3 Iron(II) Sulphate - FeSO4 Iron(II) Chloride - FeCl2 Iron(II) Nitrate - Fe2(NO3)3
FeI2 iron(II) fluoride FeBr2 iron(II) bromide FeO Fe (NO3)2 FeCO3 FeSO4 Fe Cl2 iron(II) chloride Fe2O3 iron (III) oxide Fe2(NO3)3 iron(II nitrate Fe2(CO3)3 iron(III) carbonate) Fe2 (SO4)3 iron (IIsulfate Fe (OH)3 iron (III) oxide
