Q. Which of the statements about the reaction below are correct? 2PbO(s) + C(s) o 2Pb(s) + CO2(g)
  1. Lead is getting reduced.
  2. Carbon dioxide is getting oxidised.
  3. Carbon is getting oxidised.
  4. Lead oxide is getting reduced.
Select the correct answer from the codes given below:

Answer: Only 1 and 3
Notes: The correct statements about the reaction 2PbO(s) + C(s) → 2Pb(s) + CO2(g) are:
  1. Lead is getting reduced: In this reaction, lead oxide (PbO) is being reduced to lead (Pb). Reduction is a chemical process that involves the gain of electrons or a decrease in oxidation state. In this case, lead is gaining electrons, so it is being reduced.
  2. Carbon dioxide is getting oxidized: In the reaction, carbon (C) from solid carbon is combining with oxygen from lead oxide (PbO) to form carbon dioxide (CO2). Oxidation is a chemical process that involves the loss of electrons or an increase in oxidation state. In this case, carbon is losing electrons and gaining oxygen, so it is being oxidized.
Therefore, the statements "Lead is getting reduced" and "Carbon dioxide is getting oxidized" are correct. The statements "Carbon is getting oxidized" and "Lead oxide is getting reduced" are incorrect.
