Question

H2 S -->SO2->SO3->Na2 SO4->BaSO4H2 SO4 ->MgSO4

Answer 1

2H₂S + 3O₂ = 2SO₂ + 2H₂O
2SO₂ + O₂ = 2SO₃
SO₃ + 2NaOH = Na₂SO₄ + H₂O
Na₂SO₄ + BaCl₂ = BaSO₄ + 2NaCl


H2 SO4 ->MgSO4 ??? отдельная цепочка р-ций или откуда-то ответвление?

Answer 2

The given sequence describes a series of chemical reactions involving different compounds. Let's break down each step:

1. H2S -> SO2: This reaction represents the decomposition of hydrogen sulfide (H2S) into sulfur dioxide (SO2).

2. SO2 -> SO3: This reaction represents the oxidation of sulfur dioxide (SO2) to form sulfur trioxide (SO3).

3. SO3 -> Na2SO4: This reaction involves the reaction of sulfur trioxide (SO3) with sodium hydroxide (NaOH) to produce sodium sulfate (Na2SO4).

4. Na2SO4 -> BaSO4: This reaction represents the precipitation reaction between sodium sulfate (Na2SO4) and barium chloride (BaCl2) to form barium sulfate (BaSO4), which is insoluble and forms a solid precipitate.

5. H2SO4 -> MgSO4: This reaction represents the reaction between sulfuric acid (H2SO4) and magnesium carbonate (MgCO3) to form magnesium sulfate (MgSO4).

Please note that the reactions mentioned above are simplified representations and may involve specific conditions, catalysts, or additional reactants. It is also important to consider the stoichiometry and balanced equations to accurately represent the reactions.
