| May 1, 2021 | education
Make up the reaction equations according to the transformation scheme: S → SO2 → H2SO3 → BaSO3. Name all compounds and indicate the type of reaction.
S + O2 → SO2 (compound reaction).
S – sulfur, O2 – oxygen, SO2 – sulfur (IV) oxide.
SO2 + H2O → H2SO3 (compound reaction).
SO2 – sulfur (IV) oxide, H2O – water, H2SO3 – sulfurous acid.
H2SO3 + Ba → BaSO3 ↓ + H2 ↑ (substitution reaction).
H2SO3 – sulfurous acid, Ba – barium, BaSO3 – barium sulfite, H2 – hydrogen.
ionic view:
2H + + SO32- + Ba0 → BaSO3 ↓ + H2 ↑
