Answer 1

3S+H2O=2H2S+SO2
SO2+H2O=H2SO3
H2SO3+2NaOH=Na2SO3+H2O
Na2SO3+Ba(OH)2=2NaOH+BaSO3

Answer 2

Reaction Chain: S-SO2-SO3-H2SO4-K2SO4S-SO2-H2SO3-Na2SO3-BaSO3CL2-HCLO-KCLOCL2-HCL-NaCL-AgCL

The reaction chain you provided involves a series of chemical reactions. Let's break it down step by step:

1. Sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2): - S + O2 → SO2 [[1]]

2. Sulfur dioxide (SO2) reacts with oxygen (O2) to form sulfur trioxide (SO3): - 2SO2 + O2 → 2SO3 [[2]]

3. Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4): - SO3 + H2O → H2SO4 [[3]]

4. Sulfuric acid (H2SO4) reacts with potassium hydroxide (KOH) to form potassium sulfate (K2SO4): - H2SO4 + 2KOH → K2SO4 + 2H2O [[4]]

5. Sulfur dioxide (SO2) reacts with water (H2O) to form sulfurous acid (H2SO3): - SO2 + H2O → H2SO3 [[5]]

6. Sulfurous acid (H2SO3) reacts with sodium hydroxide (NaOH) to form sodium sulfite (Na2SO3): - H2SO3 + 2NaOH → Na2SO3 + 2H2O [[6]]

7. Barium chloride (BaCl2) reacts with sodium sulfite (Na2SO3) to form barium sulfite (BaSO3) and sodium chloride (NaCl): - BaCl2 + Na2SO3 → BaSO3 + 2NaCl [[7]]

8. Chlorine gas (Cl2) reacts with hydrochloric acid (HCl) to form hypochlorous acid (HClO): - Cl2 + HCl → HClO + HCl [[8]]

9. Hypochlorous acid (HClO) reacts with potassium hydroxide (KOH) to form potassium hypochlorite (KClO) and water (H2O): - HClO + KOH → KClO + H2O [[9]]

10. Potassium hypochlorite (KClO) reacts with hydrochloric acid (HCl) to form chlorine gas (Cl2) and potassium chloride (KCl): - KClO + HCl → Cl2 + KCl [[10]]

11. Chlorine gas (Cl2) reacts with hydrochloric acid (HCl) to form hydrochloric acid (HCl) and sodium chloride (NaCl): - Cl2 + HCl → HCl + NaCl [[11]]

12. Hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to form sodium chloride (NaCl) and water (H2O): - HCl + NaOH → NaCl + H2O [[12]]

13. Silver nitrate (AgNO3) reacts with hydrochloric acid (HCl) to form silver chloride (AgCl) and nitric acid (HNO3): - AgNO3 + HCl → AgCl + HNO3 [[13]]
