Given the balanced equation representing a reaction:

Fe2O3 + 2Al Al2O3 + 2Fe

During this reaction, the oxidation number of Al changes from

A) +3 to 0 as electrons are transferred

B) +3 to 0 as protons are transferred

C) 0 to +3 as electrons are transferred

D) 0 to +3 as protons are transferred

Respuesta :

Answer:

C) 0 to +3 as electrons are transferred

Explanation:

[tex]Fe_{2}O_{3} + 2Al^{0} --> Al^{+3}_{2}O_{3} + 2Fe\\\\Al^{0} -3e^{-}--> Al^{+3}[/tex]
