Question

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

Answer 1

C) 0 to +3 as electrons are transferred

Step-by-step explanation:

`Fe_(2)O_(3) + 2Al^(0) --> Al^(+3)_(2)O_(3) + 2Fe\\\\Al^(0) -3e^(-)--> Al^(+3)`
