Co2→BaCo3→BaO→Ba(OH)2➝Ba2Cl →BaSo4

Answer 1

1. CO₂ + BaO → BaCO₃

2. BaCO₃ \(\underrightarrow{to}\) BaO + CO₂

3. BaO + H₂O → Ba(OH)₂

4. Ba(OH)₂ + 2HCl → BaCl₂ + 2H₂O

5. BaCl₂ + Na₂SO₄ → 2NaCl + BaSO₄

Answer 2

PTHH:
1. CO₂ + BaO \(\rightarrow\) BaCO₃
2. BaCO₃ \(\underrightarrow{to}\) BaO + CO₂
3.BaO + H2O \(\rightarrow\) Ba(OH)2
4.Ba(OH)₂ + 2HCl \(\rightarrow\)BaCl₂ + 2H₂O
5. BaCl₂ + K₂SO₄ \(\rightarrow\) BaSO₄ + 2KCl
