Question

осуществиет цепочку превращений fe-FeCl3-X-Fe(No3)3-Zn(No3)2

Answer 1

fe-FeCl3-X-Fe(No3)3-Zn(No3)2

 2Fe + 3Cl2 = 2FeCl3

FeCl3 + 3KOH = Fe(OH)3 + 3KCl

Fe(OH)3 + 3HNO3 = Fe(NO3)3 + 3H2O

2Fe(NO3)3 + 3PbCl2 = 2FeCl3 + 3Pb(NO3)2

 

Answer 2

Chain of Transformations: fe-FeCl3-X-Fe(No3)3-Zn(No3)2

To understand the chain of transformations from fe to Zn(No3)2, let's break it down step by step:

1. fe to FeCl3: - The symbol "fe" likely refers to iron (Fe) in its elemental form. - To convert iron (Fe) to iron(III) chloride (FeCl3), we need to react it with chlorine (Cl2) gas or hydrochloric acid (HCl). - The balanced equation for the reaction between iron and chlorine gas is: 2Fe + 3Cl2 → 2FeCl3. - Alternatively, the reaction between iron and hydrochloric acid can be represented as: 2Fe + 6HCl → 2FeCl3 + 3H2.

2. FeCl3 to X: - The specific compound represented by "X" is not provided in the question. - Without further information, it is not possible to determine the exact transformation from FeCl3 to X.

3. X to Fe(No3)3: - The compound "X" is transformed into iron(III) nitrate (Fe(No3)3). - To convert X to Fe(No3)3, we need to react it with nitric acid (HNO3). - The balanced equation for the reaction between X and nitric acid is: X + 6HNO3 → Fe(No3)3 + 3H2O.

4. Fe(No3)3 to Zn(No3)2: - Finally, iron(III) nitrate (Fe(No3)3) is transformed into zinc nitrate (Zn(No3)2). - To convert Fe(No3)3 to Zn(No3)2, we need to react it with zinc (Zn). - The balanced equation for the reaction between Fe(No3)3 and zinc is: 2Fe(No3)3 + 3Zn → 3Zn(No3)2 + 2Fe.

Please note that the specific compound represented by "X" is not provided, so the exact transformation from FeCl3 to X cannot be determined without further information.
