Объяснение:

Ba → BaO:

Ba + O2 → BaOBaO → Ba(OH)2:

BaO + H2O → Ba(OH)2Ba → BaSO4:

Ba + H2SO4 → BaSO4 + H2OS → SO2:

S + O2 → SO2SO2 → SO3:

2 SO2 + O2 → 2 SO3SO3 + H2O → H2SO4:

SO3 + H2O → H2SO4BaSO4 → Ba + H2SO4:

BaSO4 + 2 H2SO4 → Ba(HSO4)2Ряд по возрастанию активности металлов: Hg, Cu, Ag, Au, Pt

Answer 3

Equations for the Given Transformations:

1. Ba → BaO → Ba(OH)₂: - The first transformation is the conversion of barium (Ba) to barium oxide (BaO). - The equation for this reaction is: 2Ba + O₂ → 2BaO [[1]]. - The second transformation is the conversion of barium oxide (BaO) to barium hydroxide (Ba(OH)₂). - The equation for this reaction is: BaO + H₂O → Ba(OH)₂ [[2]].

2. S → SO₂ → SO₃ → H₂SO₄: - The first transformation is the conversion of sulfur (S) to sulfur dioxide (SO₂). - The equation for this reaction is: S + O₂ → SO₂ [[3]]. - The second transformation is the conversion of sulfur dioxide (SO₂) to sulfur trioxide (SO₃). - The equation for this reaction is: 2SO₂ + O₂ → 2SO₃ [[4]]. - The third transformation is the conversion of sulfur trioxide (SO₃) to sulfuric acid (H₂SO₄). - The equation for this reaction is: SO₃ + H₂O → H₂SO₄ [[5]].

3. BaSO₄: - The transformation involving barium sulfate (BaSO₄) does not involve any reaction. BaSO₄ is a compound that does not readily react with other substances under normal conditions.

Arrangement of the Transformations:

The given transformations can be arranged in the following order:

1. Ba → BaO → Ba(OH)₂ 2. S → SO₂ → SO₃ → H₂SO₄ 3. BaSO₄

This arrangement represents the sequential transformations of the given substances.
