Question

Choose the correct statement(s) for the following reaction: 8Fe(s) + S8 (s) → 8 FeS (s) (a) Iron is being oxidized. (b) Iron is being reduced. (c) Sulfur is being oxidized. (d) Sulfur is being reduced

Answer 1

Answer:

(a) Iron is being oxidized.

(d) Sulfur is being reduced.

Explanation:

Let's consider the following redox reaction.

8 Fe(s) + S₈(s) → 8 FeS(s)

Iron is being oxidized according to the following oxidation half-reaction:

Fe(s) → Fe²⁺(s) + 2 e⁻

Sulfur is being reduced according to the following reduction half-reaction:

S₈(s) + 16 e⁻ → 8 S²⁻(s)
