Question

FeCl3 --> Fe(ОН)3 --> Fe2(SO4)3 --> BaSO4

Answer 1

1) FeCl3 + 3H2O = Fe(OH)3 + 3HCl

2) 2Fe(OH)3 + 3H2SO4 = 6H2O+ Fe2(SO4)3

3) Fe2(SO4)3 + 3Ba(OH)2 + 2Fe(OH)3 + 3BaSO4

Answer 2

2FeCl3+3Ca(OH)2=2Fe(OH)3+3CaCl2
2Fe(OH)3+3CaSo4=Fe2(SO4)3+3Ca(OH)2
Fe2(SO4)3+3Ba(OH)2=3BaSO4+2Fe(OH)3

Answer 3

The chemical equation you provided shows a series of reactions starting with FeCl3 and ending with the formation of BaSO4. Here's a brief explanation of each step:

1. FeCl3 (Iron(III) chloride) reacts with water (H2O) to form Fe(OH)3 (Iron(III) hydroxide) and HCl (hydrochloric acid).

FeCl3 + 3H2O → Fe(OH)3 + 3HCl

2. Fe(OH)3 reacts with sulfuric acid (H2SO4) to form Fe2(SO4)3 (Iron(III) sulfate) and water (H2O).

2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O

3. Finally, the Fe2(SO4)3 is mixed with barium chloride (BaCl2) to form BaSO4 (barium sulfate) and FeCl2 (Iron(II) chloride).

Fe2(SO4)3 + 3BaCl2 → 3BaSO4 + 2FeCl2

This reaction sequence is an example of a series of chemical reactions where the products of one reaction become the reactants of the next reaction.
