Identify the substance s that are oxidised and the substances that are reduced in the given reaction: 2PbO + C------------> 2Pb +CO2

solution:
            Oxidation means addition of oxygen or removal of hydrogen.
           Reduction means addition of hydrogen or removal of Oxygen.

                       2PbO + C------------> 2Pb +CO2
So in the above reaction ,
                   1. Pb is reduced .  ( From PbO to Pb ) .
                    2. C is oxidised (From C to
CO2 ) .
Hope this helps You!!
Thank You!!!
