"Fe2O3 is converted into metallic Fe. Write the redox half equation."
When I did it, I used water and H+ for balancing, however, the solution does not include both of these species.
Is my answer right?
Thanks in advance :)

This would also avoid issues with where the H+ ions came from

Hey guys, this question if from the Heinemann Chapter 5 review.
"Fe2O3 is converted into metallic Fe. Write the redox half equation."
When I did it, I used water and H+ for balancing, however, the solution does not include both of these species.

Thanks in advance :)
is this the thermite reaction?

The reaction is
have to know the context to properly do this question, in this reaction, the paste is put over where the iron is needed, no water, air [and especially no H+] can get in, and consequently, you can't use them in your equation. Though this most probably won't be in an VCE exam.
