Question

ОСУЩЕСТВИТЕ ЦЕПОЧКИ ПРЕВРАЩЕНИЙ!!ПОЖАЛУЙСТА!!! 1) Li → Li2O → LiOH → LiCl 2) S → SO2 → H2SO3 → Na2SO3

Answer 1

Приветствую.
          ₁           ₂          ₃ 
А) Li → Li₂O → LiOH → LiCl
1. 4Li + O₂ = 2Li₂O
2. Li₂O + H₂O = 2LiOH
3. LiOH + HCl = LiCl + H₂O
           ₁         ₂              ₃
Б) S → SO₂ → H₂SO₃ → Na₂SO₃
1. S + O₂ = SO₂
2. SO₂ + H₂O = H₂SO₃
3. 2H₂SO₃ + NaOH = Na₂SO₃ + H₂O

Answer 2

Chain of Transformations:

1) Li → Li2O → LiOH → LiCl 2) S → SO2 → H2SO3 → Na2SO3

Let's break down each chain of transformations:

1) Li → Li2O → LiOH → LiCl: - Lithium (Li) reacts with oxygen (O) to form lithium oxide (Li2O) [[1]]. - Lithium oxide (Li2O) reacts with water (H2O) to form lithium hydroxide (LiOH) [[2]]. - Lithium hydroxide (LiOH) reacts with hydrochloric acid (HCl) to form lithium chloride (LiCl) [[3]].

2) S → SO2 → H2SO3 → Na2SO3: - Sulfur (S) reacts with oxygen (O) to form sulfur dioxide (SO2) [[4]]. - Sulfur dioxide (SO2) dissolves in water (H2O) to form sulfurous acid (H2SO3) [[5]]. - Sulfurous acid (H2SO3) reacts with sodium hydroxide (NaOH) to form sodium sulfite (Na2SO3) [[6]].

Please note that these reactions are simplified representations and may involve additional steps or intermediates in reality.
