Identigy the substance oxidised & reduced : ZnO + C ---> Zn + CO
Hi,
ZnO(s)+C(s)→Zn(s)+CO(g)
Since oxygen has combined with carbon, carbon is the one that is oxidized and ZnO is the oxidizing agent. Similarly carbon has taken the oxygen of ZnO, carbon is the reducing agent and ZnO is the one that has been reduced.
Reducing agent-C
Oxidizing agent-ZnO
Oxidized-C
Reduced- ZnO
Hope it helps.
Cheers!
