Hi
Please look at this link. It is only very brief. It describes how to extract iron from iron oxide on a match head.
My questions are:
where does the carbon come from in this equation
Iron(III) oxide + carbon → iron + carbon dioxide
2Fe2O3(s) + 3C(s) → 4Fe(s) + 3CO2(g)
Is it from the wood in the match?
Why sodium carbonate is needed? The page says:
The sodium carbonate fuses easily and brings the iron oxide into close contact with the carbon.
I don't really know what that means
thanks
