Question

Which answer best describes what is happening in the following redox reaction? 4Fe + 3O2 mc023-1.jpg 2Fe2O3 This is combustion. This is neutralization. Iron is oxidized to form rust. Oxygen is oxidized to form rust.

Answer 1

C ( iron is oxidized to form rust)

Step-by-step explanation:

Answer 2

Answer is: iron is oxidized to form rust.

Chemical reaction: Fe + O₂ → Fe₂O₃.

Oxidation half reaction: Fe⁰ → Fe⁺³ + 3e⁻ /×4; 4Fe⁰ → 4Fe⁺³ + 12e⁻.

Reduction half reaction: O₂⁰+ 4e⁻ → 2O⁻²/×3; 3O₂⁰+ 12e⁻ → 6O⁻².

Balanced chemical reaction: 4Fe + 3O₂ → 2Fe₂O₃.

Oxidation is increase of oxidation number, iron is oxidized from oxidation number 0 (Fe) to oxidation number +3 (in rust Fe₂O₃).
