Question

Ba-BaO-Ba(OH)2-BaCl2-BaCO3-CO2​

Answer 1

Ответ:

Ba → BaO → Ba(OH)₂ → BaCl₂ → BaCO₃ → CO₂

Объяснение:

2Ba + О₂ → 2BaO

BaO + H₂O → Ba(OH)₂

Ba(OH)₂ + 2HCl → BaCl₂ + 2H₂O

BaCl₂ + Na₂CO₃ → BaCO₃ + 2NaCl

BaCO₃ + H₂O → CO₂ + Ba(OH)₂

Answer 2

Ответ:

2Ba+O2=2BaO

BaO+H2O=Ba(OH)2

Ba(OH)2+2HCl=BaCl2+2H2O

BaCl2 + Na2CO3 = BaCO3↓+2NaCl

BaCO3⇒BaO+CO2↑

Answer 3

The sequence you provided represents a chemical reaction involving several compounds. Here's a breakdown of the reaction:

1. BaO (Barium Oxide): This is a solid compound.
2. Ba(OH)2 (Barium Hydroxide): This is also a solid compound.
3. BaCl2 (Barium Chloride): This is a solid compound.
4. BaCO3 (Barium Carbonate): This is a solid compound.
5. CO2 (Carbon Dioxide): This is a gas.

The reaction can be represented as follows:

BaO + H2O -> Ba(OH)2 (Reaction 1) Ba(OH)2 + 2HCl -> BaCl2 + 2H2O (Reaction 2) BaCl2 + Na2CO3 -> BaCO3 + 2NaCl (Reaction 3) BaCO3 -> BaO + CO2 (Reaction 4)

Overall, the sequence represents a series of reactions where BaO and water react to form Ba(OH)2, Ba(OH)2 reacts with hydrochloric acid (HCl) to form BaCl2 and water, BaCl2 reacts with sodium carbonate (Na2CO3) to form BaCO3 and sodium chloride (NaCl), and finally, BaCO3 decomposes to form BaO and CO2.

Please note that this breakdown assumes the reactions are taking place under appropriate conditions and in the presence of the necessary reactants.
