Question

S–>SO2–>SO3–>H2SO4–>BaSO4

Answer 1

Ответ:

$S + O_2_ = SO_2\\2SO_2 + O_2 = 2SO_3\\SO_3 + H_2O= H_2SO_4\\H_2SO_4 + Ba(OH)_2 = BaSO_4 + 2H_2O$

Answer 2

The expression you provided appears to be a sequence of chemical reactions involving sulfur dioxide (SO2) and sulfur trioxide (SO3) leading to the formation of sulfuric acid (H2SO4) and then barium sulfate (BaSO4). Let's break down each step of the reaction:

1. SO2 (sulfur dioxide) reacts with oxygen (O2) to form SO3 (sulfur trioxide).
2. SO3 (sulfur trioxide) reacts with water (H2O) to produce sulfuric acid (H2SO4).
3. Sulfuric acid (H2SO4) can react with barium chloride (BaCl2) to form barium sulfate (BaSO4).

The overall reaction can be represented as follows:

SO2 + O2 → SO3 + H2O → H2SO4 + BaCl2 → BaSO4 + HCl

Note: The above reaction is a general representation and might not be the exact reaction conditions or stoichiometry used in the laboratory.

Please keep in mind that chemical reactions often require specific conditions (such as temperature, pressure, catalysts, etc.) for them to proceed effectively. Additionally, reactions can have multiple steps, intermediates, and side reactions that might not be explicitly shown in the given expression.
