After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react w
sammy [17]

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
