SpletHere zinc is reduced by gaining electrons which changes its oxidation state from + 2 to 0. Whereas, Carbon is getting oxidized by losing electrons which change its oxidation state from 0 to + 2. Hence,In ZnO + C → Zn + CO, Carbon is oxidized (due to loss of electrons) and Zinc is reduced (due to gain in electrons). Suggest Corrections.
