Question

Запишите реакции для следующей цепочки превращения:S-CiS-SO2-Na2SO3-SO2-SO3-H2SO4-BaSO4

Answer 1

S+Cu=CuS
2CuS+3O2=2CuO + SO2
SO2+2NaOH=Na2SO3+H2O
Na2SO3 + 2HCl=2NaCl+H2O+SO2
2SO2+O2=2SO3
SO3+H2O=H2SO4
H2SO4+Ba(OH)2=BaSO4+2H2O

Answer 2

Reaction Chain:

The reactions for the given transformation are as follows:

1. S → ClS 2. ClS → SO2 3. SO2 → Na2SO3 4. Na2SO3 → SO2 5. SO2 → SO3 6. SO3 → H2SO4 7. H2SO4 → BaSO4

Explanation:

1. S → ClS - The transformation of S to ClS involves the addition of a chlorine atom to the sulfur atom.

2. ClS → SO2 - The conversion of ClS to SO2 likely involves the removal of the chlorine atom and the formation of sulfur dioxide.

3. SO2 → Na2SO3 - The conversion of SO2 to Na2SO3 is not directly provided in the search results. However, it is known that sulfur dioxide can react with sodium hydroxide to form sodium sulfite (Na2SO3).

4. Na2SO3 → SO2 - The reverse reaction of Na2SO3 to SO2 involves the decomposition of sodium sulfite to produce sulfur dioxide.

5. SO2 → SO3 - The conversion of SO2 to SO3 involves the addition of an oxygen atom to sulfur dioxide.

6. SO3 → H2SO4 - The transformation of SO3 to H2SO4 involves the reaction of sulfur trioxide with water to produce sulfuric acid.

7. H2SO4 → BaSO4 - The reaction of sulfuric acid with barium chloride (BaCl2) results in the formation of barium sulfate (BaSO4).

Chemical Equations:

The chemical equations for the reactions are as follows:

1. S + Cl2 → ClS 2. ClS + O2 → SO2 3. SO2 + NaOH → Na2SO3 4. Na2SO3 → SO2 + Na2O 5. 2SO2 + O2 → 2SO3 6. SO3 + H2O → H2SO4 7. H2SO4 + BaCl2 → BaSO4 + 2HCl

The specific conditions and reagents for each transformation may vary, but the overall reactions follow these general principles.

I hope this helps! If you have further questions or need additional information, feel free to ask.
