Question

SO2→ Н2SO3→ SO2 → SO3→ BаSO4

Answer 1

Ответ:

S+O2=SO2

SO2+H2O=H2SO3

H2SO3+BaO=BaSO3+H2O

BaSO3+2HCl=BaCl2+SO2+H2O

2SO2+O2=2SO3

SO3+BaO=BaSO4

Объяснение:

S+O2=SO2

SO2+H2O=H2SO3

H2SO3+BaO=BaSO3+H2O

BaSO3+2HCl=BaCl2+SO2+H2O

2SO2+O2=2SO3

SO3+BaO=BaSO4

Answer 2

It seems like you've listed a series of chemical reactions involving sulfur dioxide (SO2) and its transformation into various compounds. Let me break down each step for you:

1. SO2: Sulfur dioxide is a gaseous compound composed of one sulfur atom and two oxygen atoms. It is produced from various sources, including the combustion of fossil fuels, volcanic activity, and some industrial processes.

2. H2SO3: Sulfur dioxide can dissolve in water to form sulfurous acid (H2SO3). This reaction involves the hydration of SO2:

   SO2 + H2O → H2SO3

3. SO3: Sulfurous acid (H2SO3) is unstable and tends to decompose into sulfur trioxide (SO3) and water:

   2H2SO3 → 3SO2 + H2O

4. BaSO4: Sulfur trioxide (SO3) can react with barium sulfate (BaSO4) to produce barium metabisulfite (BaS2O5):

   SO3 + BaSO4 → BaS2O5

However, in the sequence you provided, the formation of barium sulfate (BaSO4) seems to be indicated as the final product, which might be a typo or misunderstanding. Barium sulfate is commonly formed by the reaction of barium chloride (BaCl2) with a sulfate source (like sulfuric acid, H2SO4):

BaCl2 + H2SO4 → BaSO4 + 2HCl

If you have any specific questions about these reactions or if you meant something else, please feel free to clarify!
