Question

Identify reductants and oxidants in the following 1] 2PbO + C -----> 2Pb + CO2 . 2] 4NH3 + 5O2 -----> 4HNO3 + H2O ​

Answer 1

Answer:

2PbO+C→2Pb+CO

2

Pb

2+

→Pb (i.e. reduction)

C

+0

→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.
