Question

FeCl3+FeCl2+FeSO4+Fe(OH)2+FeO+Fe+Fe2(SO4)3

Answer 1

1)Fe + 2HCl = FeCl2 +H2
2)2FeCl2 + Cl2 =FeCl3
3)FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
4)2Fe(OH)3 + 3H2SO4 = Fe2(SO4)3 + 3H2O
5)Fe2(SO4)3 + 3Ba(NO3)2 = 2Fe(NO3)3 + 3BaSO4

Answer 2

FeCl3, FeCl2, FeSO4, Fe(OH)2, FeO, Fe, and Fe2(SO4)3 are all chemical compounds containing iron (Fe) in different oxidation states and with different combinations of other elements.

FeCl3 (Ferric Chloride):

- Ferric chloride is an inorganic compound with the formula FeCl3. - It is a brownish-red solid that is highly soluble in water. - Ferric chloride is commonly used as a flocculant in wastewater treatment, as a catalyst in organic synthesis, and in the etching of printed circuit boards. - The reaction between iron and chlorine gas produces ferric chloride: Fe + 3Cl2 → 2FeCl3.

FeCl2 (Ferrous Chloride):

- Ferrous chloride is an inorganic compound with the formula FeCl2. - It is a greenish-white solid that is soluble in water. - Ferrous chloride is used as a reducing agent, in the production of pigments, and in the treatment of sewage and industrial waste. - Ferrous chloride can be prepared by the reaction of iron with hydrochloric acid: Fe + 2HCl → FeCl2 + H2.

FeSO4 (Ferrous Sulfate):

- Ferrous sulfate is an inorganic compound with the formula FeSO4. - It is a pale green or blue-green solid that is highly soluble in water. - Ferrous sulfate is commonly used as a nutritional supplement, in the treatment of iron deficiency anemia, and as a reducing agent in various chemical reactions. - Ferrous sulfate can be prepared by the reaction of iron with sulfuric acid: Fe + H2SO4 → FeSO4 + H2.

Fe(OH)2 (Iron(II) Hydroxide):

- Iron(II) hydroxide is an inorganic compound with the formula Fe(OH)2. - It is a greenish solid that is sparingly soluble in water. - Iron(II) hydroxide is used in water treatment processes and as a precursor for the synthesis of other iron compounds. - Iron(II) hydroxide can be prepared by the reaction of iron salts with alkali hydroxides: FeCl2 + 2KOH → Fe(OH)2 + 2KCl.

FeO (Iron(II) Oxide):

- Iron(II) oxide is an inorganic compound with the formula FeO. - It is a black solid that is used as a pigment and in the production of steel. - Iron(II) oxide can be prepared by the reduction of iron(III) oxide with carbon monoxide: Fe2O3 + 3CO → 2FeO + 3CO2.

Fe (Iron):

- Iron is a chemical element with the symbol Fe and atomic number 26. - It is a metal that is commonly found in the Earth's crust and has various industrial applications. - Iron is used in the production of steel, as a component in many alloys, and in the manufacturing of machinery, vehicles, and construction materials. - Iron is also an essential nutrient for many living organisms, including humans, and is involved in various biological processes.

Fe2(SO4)3 (Ferric Sulfate):

- Ferric sulfate is an inorganic compound with the formula Fe2(SO4)3. - It is a yellowish solid that is highly soluble in water. - Ferric sulfate is used as a coagulant in water treatment, as a mordant in dyeing and printing textiles, and in the synthesis of other iron compounds. - Ferric sulfate can be prepared by the reaction of iron with sulfuric acid: 2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2.
