Question

an important class 35. *Redox reactions are of reactions. The oxidation and reduction reactions always occur simultaneously, such and odo autoxida and ketc and odo undesirc class of chemical reactions is named as the redox reaction or Oxidation-Reduction reaction. The substance getting reduced in a chemical reaction is known as the oxidizing agent, while a substance that is getting oxidized is known as the reducing agent. The activity in which copper powder is taken in a china dish and heated helps in understanding redox reactions. (A) What happens when copper powder is heated in a china dish? Explain your observation. (B) What will you observe if hydrogen gas is passed over the heated material obtained in (A) above? (C) Bidentify the substance oxidized and substance reduced in the reaction at (B) above. (D) @identify the correct statement: In the reaction between lead sulphide and hydrogen peroxide shown by the Which for th a long (a) C (b) N (d) Ans. (d) Expl both sam rea Thu for wit stc 37. A te: equation below, PbS+ 2H202 → PbSO4 + 4H20, (a) Lead sulphide is reduced and Hydrogen peroxide is oxidized. (b) Lead sulphide is oxidized and Hydrogen peroxide is reduced.
