Question

Здійсніть перетворення: S -> SO2 -> H2SO3 -> Na2SO3 -> CaSO3​

Answer 1

Ответ:

1) S + O2 ---> SO2

2) SO2 + H2O ---> H2SO3

3) H2SO3 + 2NaOH ---> Na2SO3 + 2H2O

4) Na2SO3 + Ca(OH)2 ---> 2NaOH + CaSO3 (стрелочка вниз)

Answer 2

S (Sulfur) -> SO2 (Sulfur dioxide) -> H2SO3 (Sulfurous acid) -> Na2SO3 (Sodium sulfite) -> CaSO3 (Calcium sulfite)

1. S (Sulfur) is oxidized to form: SO2 (Sulfur dioxide)

2. SO2 (Sulfur dioxide) dissolves in water and reacts with water to form: H2SO3 (Sulfurous acid)

3. H2SO3 (Sulfurous acid) reacts with sodium hydroxide (NaOH) to form: Na2SO3 (Sodium sulfite) and water (H2O)

4. Na2SO3 (Sodium sulfite) reacts with calcium chloride (CaCl2) to form: CaSO3 (Calcium sulfite) and sodium chloride (NaCl)
