Question

Помогите пожалуйста по химии! Написать молекулярные уравнения реакций. Ba→BaO→Ba(OH)2→BaCl2

Answer 1

2Ba+O²➡2BaO
BaO+H²O➡Ba(OH)²
Ba(OH)²+2HCl➡BaCl²+2H²O

Answer 2

Molecular Equations for the Given Reactions

1. Barium (Ba) to Barium Oxide (BaO): - The reaction of barium with oxygen forms barium oxide. - The balanced molecular equation for this reaction is: ``` 2 Ba + O2 → 2 BaO ``` 2. Barium Oxide (BaO) to Barium Hydroxide (Ba(OH)2): - Barium oxide reacts with water to form barium hydroxide. - The balanced molecular equation for this reaction is: ``` BaO + H2O → Ba(OH)2 ```

3. Barium Hydroxide (Ba(OH)2) to Barium Chloride (BaCl2): - Barium hydroxide reacts with hydrochloric acid to form barium chloride. - The balanced molecular equation for this reaction is: ``` Ba(OH)2 + 2 HCl → BaCl2 + 2 H2O ``` I hope this helps!
