Molecular Equations for the Given Reactions:

1. Ca → CaO → Ca(OH)2 → CaCl2 → AgCl2 2. S → SO2 → H2SO3 → Na2SO3 → SO2

Chemical Reactions in Light of Electrolytic Dissociation and Redox Processes:

1. Ca → CaO: - This is a synthesis reaction where calcium (Ca) reacts with oxygen (O) to form calcium oxide (CaO). - The reaction can be represented as: Ca(s) + O2(g) → CaO(s).

2. CaO → Ca(OH)2: - This is a reaction where calcium oxide (CaO) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2). - The reaction can be represented as: CaO(s) + H2O(l) → Ca(OH)2(aq).

3. Ca(OH)2 → CaCl2: - This is a reaction where calcium hydroxide (Ca(OH)2) reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2) and water (H2O). - The reaction can be represented as: Ca(OH)2(aq) + 2HCl(aq) → CaCl2(aq) + 2H2O(l).

4. CaCl2 → AgCl2: - This reaction involves the displacement of silver (Ag) from silver nitrate (AgNO3) by calcium chloride (CaCl2), resulting in the formation of silver chloride (AgCl) and calcium nitrate (Ca(NO3)2). - The reaction can be represented as: CaCl2(aq) + 2AgNO3(aq) → 2AgCl(s) + Ca(NO3)2(aq).

5. S → SO2: - This is a combustion reaction where sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2). - The reaction can be represented as: S(s) + O2(g) → SO2(g).

6. SO2 → H2SO3: - This is a reaction where sulfur dioxide (SO2) reacts with water (H2O) to form sulfurous acid (H2SO3). - The reaction can be represented as: SO2(g) + H2O(l) → H2SO3(aq).

7. H2SO3 → Na2SO3: - This is a reaction where sulfurous acid (H2SO3) reacts with sodium hydroxide (NaOH) to form sodium sulfite (Na2SO3) and water (H2O). - The reaction can be represented as: H2SO3(aq) + 2NaOH(aq) → Na2SO3(aq) + 2H2O(l).

8. Na2SO3 → SO2: - This is a decomposition reaction where sodium sulfite (Na2SO3) decomposes to form sulfur dioxide (SO2) and sodium oxide (Na2O). - The reaction can be represented as: 2Na2SO3(s) → 2Na2O(s) + 3SO2(g).
