Question

$2PbO+C\to 2Pb+C{O}_2$ is an example of _______

• A. oxiation reaction
  
• B. reduction reaction
  
• C. redox reaction
  
• D. none

Answer 1

Answer: (C)

redox reaction

$2PbO+C\to 2Pb+C{O}_2$

$P{b}^{2+}\to Pb$ (i.e. reduction)
$C^{+0}\to C^{+4}$ (i.e. oxidation)

As reduction and oxidation, both reactions are there, so it is a redox reaction, where C gets oxidized and Pb gets reduced.
