Question

Ba⇒BaO⇒Ba(OH)2⇒BaCl2⇒BaSO4

Answer 1

Ответ:

Первое действие:Ba + O₂ = 2BaO

Второе действие:BaO + H₂O = Ba(OH)₂

Третье действие:Ba(OH)₂ + 2HCl = BaCl₂ + 2H₂O

Четвёртое действие:Na₂SO₄ + BaCl₂ = BaSO₄ + 2NaCl

Answer 2

The sequence you provided represents a series of chemical reactions involving the element barium (Ba) and various compounds. Let's break down each step:

1. Ba ⇒ BaO: This reaction represents the formation of barium oxide (BaO) from elemental barium (Ba) by combining it with oxygen. The balanced chemical equation for this reaction is: 2Ba + O2 → 2BaO

2. BaO ⇒ Ba(OH)2: This reaction involves the reaction of barium oxide (BaO) with water (H2O) to form barium hydroxide (Ba(OH)2). The balanced chemical equation for this reaction is: BaO + H2O → Ba(OH)2

3. Ba(OH)2 ⇒ BaCl2: This step involves the reaction of barium hydroxide (Ba(OH)2) with hydrochloric acid (HCl) to form barium chloride (BaCl2) and water (H2O). The balanced chemical equation for this reaction is: Ba(OH)2 + 2HCl → BaCl2 + 2H2O

4. BaCl2 ⇒ BaSO4: This reaction represents the reaction of barium chloride (BaCl2) with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and hydrochloric acid (HCl). The balanced chemical equation for this reaction is: BaCl2 + H2SO4 → BaSO4 + 2HCl

So, the overall sequence of reactions can be summarized as:

Ba → BaO → Ba(OH)2 → BaCl2 → BaSO4

Each step involves a specific reaction with different reactants and products.
