Question

S->SO2->H2SO3->BaSO3->SO2->SO3->BASO3 S->HgS->SO2->SO3->H2SO4

Answer 1

S + O2 -> SO2

SO2 + H2O -> H2SO3

Ba(OH)2 + H2SO3 -> BaSO3 + 2H2O

BaSO3 -(t°)-> BaO + SO2

2SO2 + O2 -> 2SO3

SO3 + Ba(OH)2 -> BaSO4 + H2O

S + Hg -> HgS

2HgS + 3O2 -> 2HgO + 2SO2

2SO2 + O2 -> 2SO3

SO3 + H2O -> H2SO4

Answer 2

It seems like you have provided a series of chemical reactions involving different compounds. Let's analyze each step of the reactions:

1. S -> SO2: S (elemental sulfur) reacts with oxygen to form sulfur dioxide (SO2).

2. SO2 -> H2SO3: Sulfur dioxide (SO2) reacts with water (H2O) to form sulfurous acid (H2SO3).

3. H2SO3 -> BaSO3: Sulfurous acid (H2SO3) reacts with barium hydroxide (Ba(OH)2) to form barium sulfite (BaSO3).

4. BaSO3 -> SO2: Barium sulfite (BaSO3) decomposes into sulfur dioxide (SO2) and barium oxide (BaO).

5. SO2 -> SO3: Sulfur dioxide (SO2) is oxidized to sulfur trioxide (SO3).

6. SO3 -> BASO3: Sulfur trioxide (SO3) reacts with barium hydroxide (Ba(OH)2) to form barium sulfate (BaSO4).

7. S -> HgS: Elemental sulfur (S) reacts with mercury (II) nitrate (Hg(NO3)2) to form mercury (II) sulfide (HgS).

8. HgS -> SO2: Mercury (II) sulfide (HgS) is heated, producing sulfur dioxide (SO2) and mercury metal (Hg).

9. SO2 -> SO3: Sulfur dioxide (SO2) is oxidized to sulfur trioxide (SO3).

10. SO3 -> H2SO4: Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4).

Please note that these reactions may involve specific reaction conditions, catalysts, or other reagents that are not explicitly mentioned. Moreover, some of the steps may involve several intermediate reactions or side reactions. If you have any specific questions about these reactions or need further information, feel free to ask!
