Write the reaction equations that allow you to carry out the following transformations Ba- BaO- Ba (OH) 2- BaSO3 S

Write the reaction equations that allow you to carry out the following transformations Ba- BaO- Ba (OH) 2- BaSO3 S- SO2- H2SO3- BaSO3

1 chain:
1) 2Ba + O2 = 2BaO (when barium interacts with oxygen, barium oxide is formed);
2) BaO + H2O = Ba (OH) 2 (when barium oxide interacts with water, barium hydroxide is formed);
3) Ba (OH) 2 + SO2 = BaSO3 + H2O (when barium hydroxide interacts with sulfur (IV) oxide, barium sulfite and water are formed).

2 chain:
1) S + O2 = SO2 (when sulfur reacts with oxygen, sulfur (IV) oxide is formed);
2) SO2 + H2O = H2SO3 (when sulfur (IV) oxide interacts with water, sulfite acid is formed);
3) H2SO3 + BaO = BaSO3 + H2O (when sulfite acid reacts with barium oxide, barium sulfite and water are formed).
