Question

Identify the oxidizing and the reducing agent in the following reactions:-
a) 2PbO+C ---> 2Pb+Co2
b) CuO+H2 --->Cu+H2O
c)3MnO2+4Al ----> 3Mn+ 2Al2O3

Answer 1

Answer:

1.Oxidized=C

Reduced=Pb

2.Oxidized=H2

Reduced=Cu

3.Oxidized=Al

Reduced=Mn

Answer 2

Answer:

In first, lead oxide is reduced to lead, and carbon is oxidized to carbon dioxide.

In first, lead oxide is reduced to lead, and carbon is oxidized to carbon dioxide. in second, copper oxide is reduced to copper, and hydrogen is oxidized to water.

In first, lead oxide is reduced to lead, and carbon is oxidized to carbon dioxide. in second, copper oxide is reduced to copper, and hydrogen is oxidized to water. in third, manganese oxide is reduced to manganese, and aluminium is oxidized to aluminium oxide.
