Question

Fecl3=...=fe2o3=fe2(so4)3=fecl3

Answer 1

FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

2Fe(OH)3 = Fe2O3 + 3H2O

Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O

Fe2(SO4)3 +3 BaCl2 = 3BaSO4 +2 FeCl3

Answer 2

The statement "FeCl3 = Fe2O3 = Fe2(SO4)3 = FeCl3" is not entirely accurate.

FeCl3, Fe2O3, Fe2(SO4)3, and FeCl3 are all compounds containing iron (Fe) and other elements. However, they have different chemical formulas and properties.

• FeCl3: This compound is known as iron(III) chloride. It consists of one iron ion with a +3 charge and three chloride ions with a -1 charge each. Its chemical formula is FeCl3.
• Fe2O3: This compound is known as iron(III) oxide or ferric oxide. It consists of two iron ions with a +3 charge each and three oxide ions with a -2 charge each. Its chemical formula is Fe2O3.
• Fe2(SO4)3: This compound is known as iron(III) sulfate or ferric sulfate. It consists of two iron ions with a +3 charge each and three sulfate ions with a -2 charge each. Its chemical formula is Fe2(SO4)3.
• FeCl3: This compound is again iron(III) chloride and has the same chemical formula as the first compound.

So, while FeCl3 is the same compound as FeCl3, Fe2O3 and Fe2(SO4)3 are different compounds with different chemical formulas and properties.
