Question

1)H2S-S-SO2-H2SO4-BASO42)S-NAS-CUS-SO2-H2SO4​

Answer 1

Ответ:

Объяснение:

1) 2H2S + O2 = 2S + 2H2O

  S + O2 = SO2

  2SO2 + O2 = 2SO3

  SO3 + H2O = H2SO4

  H2SO4 + BaCl2 = BaSO4 + 2HCl

2) S + 2Na = Na2S

  Na2S + CuCl2 = CuS + 2NaCl

  2CuS + 3O2 = 2SO2 + 2CuO

  2SO2 + O2 = 2SO3

 SO3 + H2O = H2SO4

Answer 2

It appears that you've provided two sequences of chemical reactions involving various compounds. I'll try to break down these reactions step by step:

1. H2S -> S -> SO2 -> H2SO4 -> BaSO4

• Hydrogen sulfide (H2S) is oxidized to form sulfur (S).
• Sulfur (S) is further oxidized to sulfur dioxide (SO2).
• Sulfur dioxide (SO2) can react with water (H2O) and oxygen (O2) to form sulfuric acid (H2SO4).
• Finally, barium sulfate (BaSO4) may be formed under certain conditions.

2. S -> Na2S -> CuS -> SO2 -> H2SO4

• Sulfur (S) reacts with sodium (Na) to form sodium sulfide (Na2S).
• Sodium sulfide (Na2S) can react with copper ions (Cu2+) to form copper sulfide (CuS).
• Copper sulfide (CuS) can be oxidized to sulfur dioxide (SO2).
• Sulfur dioxide (SO2) can react with water (H2O) and oxygen (O2) to form sulfuric acid (H2SO4).

Please note that these sequences of reactions represent simplified pathways, and the actual chemical reactions and conditions involved in each step may vary depending on specific experimental conditions and reactants used. If you have any specific questions or need further details about these reactions, please feel free to ask.
