Question

S → SO 2  → SO 3  → H 2 SO 4  → Na 2 SO 4  → BaSO 4

Answer 1

S + O2 = SO2
2SO2 + O2 = 2SO3
SO3 + H2O = H2SO4
2Na + H2SO4(разб) = Na2SO4 + H2
Na2SO4 + BaCl2 = BaSO4 + 2NaCl

Answer 2

It seems like you've provided a sequence of chemical reactions starting with sulfur dioxide (SO2) and ending with barium sulfate (BaSO4). Let's break down each step in this chemical reaction sequence:

1. Sulfur Dioxide (SO2):

   • Sulfur dioxide (SO2) is a colorless gas with a pungent odor. It is formed by the combustion of sulfur-containing compounds and is a common air pollutant. SO2 is used in various industrial processes, including the production of sulfuric acid.

2. Sulfur Trioxide (SO3):

   • Sulfur trioxide (SO3) is a highly reactive compound that can be formed by the oxidation of sulfur dioxide (SO2). It is a key intermediate in the production of sulfuric acid (H2SO4).

3. Sulfuric Acid (H2SO4):

   • Sulfuric acid (H2SO4) is a strong mineral acid and one of the most important chemicals in the chemical industry. It is commonly used in the manufacture of various chemicals and as a laboratory reagent. The production of sulfuric acid typically involves the catalytic oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) and then its hydration to form H2SO4.

4. Sodium Sulfate (Na2SO4):

   • Sodium sulfate (Na2SO4) is a salt that can be produced by neutralizing sulfuric acid (H2SO4) with sodium hydroxide (NaOH) or sodium carbonate (Na2CO3). It has various industrial uses, including in detergents and the pulp and paper industry.

5. Barium Sulfate (BaSO4):

   • Barium sulfate (BaSO4) is a white crystalline solid that is virtually insoluble in water. It is often used as a contrast agent in X-ray imaging and as a component in drilling fluids in the oil and gas industry. The formation of barium sulfate can occur in the presence of barium ions and sulfate ions, typically in a precipitation reaction.

Each step in this sequence represents a chemical transformation from one compound to another, and these reactions have various practical applications in different industries. If you have specific questions about any of these reactions or their applications, feel free to ask for more details.
