madam [21]

Answer:

a. electrons are transferred from silver in AgCl (aq) to Cd (s)

Explanation:

In this reaction Ag is reduced:

  • Ag⁺ + 1e⁻ → Ag⁰

While Cd is oxidized:

  • Cd⁰ → Cd⁺² + 2e⁻

With those two semi-reactions we can see that there's a transfer of electrons from silver in AgCl(aq) to the solid cadmium.

For the record, given that Ag was reduced, Cd was the reducing agent. And because Cd was reduced, Ag was the oxidizing agent.

Ferrous sulfate (FeSO4) was used in the
BARSIC [14]

Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:

Aqueous ferric sulfate = Fe_2(SO_4)_3_{(aq)}

Gaseous sulfur dioxide = SO_2_{(g)}

Water = H_2O_{(l)}

Aqueous sulfuric acid =  H_2SO_4_{ (aq)}

Aqueous ferrous sulfate =  FeSO_4_{ (aq)}

Thus, the balance equation becomes:

Fe_2(SO_4)_3_{(aq)} +  SO_2_{(g)} + 2H_2O_{(l)} ---> 2 H_2SO_4_{ (aq)} + 2 FeSO_4_{ (aq)}
