Question

Решите цепочку. 29 б fe2s3 → h2s → s → so2 → so3 → nahso4 → na2so4 → baso4

Answer 1

Fe2S3 + 6HCl = 2FeCl3 + 3H2S
2H2S+O2 = 2S + 2H2O
S+O2 = SO2
2SO2 + O2 = 2SO3
SO3+NaOH = NaHSO4
NaHSO4 + NaOH = Na2SO4 + H2O
Na2SO4 + Ba(NO3)2 = BaSO4 + 2NaNO3

Answer 2

Fe2S3+6HCl=2FeCl3+3H2S
2H2S+O2=2S+2H2O (t)
S+O2=SO2 (t)
2SO2+O2=2SO3 (кат t)
NaOH+SO3изб=NaHSO4
NaHSO4+NaOH=Na2SO4+H2O
Na2SO4+BaCl2=BaSO4+2NaCl

Answer 3

Chain Reaction: 29b + Fe2S3 → H2S → S → SO2 → SO3 → NaHSO4 → Na2SO4 → BaSO4

Let's break down the given chain reaction step by step:

1. 29b + Fe2S3 → H2S: - The reaction between 29b and Fe2S3 produces hydrogen sulfide (H2S). Unfortunately, I couldn't find any specific information about the compound 29b. However, Fe2S3 is iron(III) sulfide, which reacts with 29b to form H2S.

2. H2S → S: - Hydrogen sulfide (H2S) decomposes to form sulfur (S). This is a decomposition reaction where H2S breaks down into its constituent elements.

3. S → SO2: - Sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2). This is a combustion reaction where sulfur reacts with oxygen to produce SO2.

4. SO2 → SO3: - Sulfur dioxide (SO2) reacts with oxygen (O2) to form sulfur trioxide (SO3). This is another combustion reaction where SO2 reacts with oxygen to produce SO3.

5. SO3 → NaHSO4: - Sulfur trioxide (SO3) reacts with sodium hydroxide (NaOH) to form sodium hydrogen sulfate (NaHSO4). This is an acid-base reaction where SO3 reacts with NaOH to produce NaHSO4.

6. NaHSO4 → Na2SO4: - Sodium hydrogen sulfate (NaHSO4) decomposes to form sodium sulfate (Na2SO4). This is a decomposition reaction where NaHSO4 breaks down into Na2SO4.

7. Na2SO4 → BaSO4: - Sodium sulfate (Na2SO4) reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4). This is a double displacement reaction where Na2SO4 reacts with BaCl2 to produce BaSO4.

Please note that the specific conditions and catalysts required for each reaction may vary. It's also important to mention that the compound 29b is not well-known, and I couldn't find any specific information about it.
