Question

2. Дана схема превращений. Составьте уравнения реакций. Ba → BaO → Ba(OH)2 → BaCl2 Укажите тип реакций.​

Answer 1

Объяснение:

Ba → BaO → Ba(OH)2 → BaCl2

2Ва + О2 = ВаО реакция соединения

ВаО + Н2О = Ba(OH)2 реакция соединения

Ba(OH)2 + 2НСl = BaCl2 + 2H2O реакция нейтрализации (обмена)

Answer 2

Given Reaction Scheme:

The given reaction scheme is as follows: Ba → BaO → Ba(OH)2 → BaCl2

Equations for the Reactions:

1. Ba → BaO: - The reaction is the formation of barium oxide from barium. - The equation for this reaction is: Ba → BaO.

2. BaO → Ba(OH)2: - The reaction is the formation of barium hydroxide from barium oxide. - The equation for this reaction is: BaO + H2O → Ba(OH)2.

3. Ba(OH)2 → BaCl2: - The reaction is the formation of barium chloride from barium hydroxide. - The equation for this reaction is: Ba(OH)2 + 2HCl → BaCl2 + 2H2O.

Types of Reactions:

1. Ba → BaO: - This is a synthesis reaction, where barium reacts with oxygen to form barium oxide.

2. BaO + H2O → Ba(OH)2: - This is a hydration reaction, where barium oxide reacts with water to form barium hydroxide.

3. Ba(OH)2 + 2HCl → BaCl2 + 2H2O: - This is a double displacement reaction, where barium hydroxide reacts with hydrochloric acid to form barium chloride and water.
