Question

2PbO(s) + C(s) - 2Pb(s) + CO2(g)​

Answer 1

Answer:

Answer : The correct option is, (b) 1 and 3

Explanation :

The balanced chemical reaction is,

2PbO(s)+C(s)\rightarrow 2Pb(s)+CO_2(g)2PbO(s)+C(s)→2Pb(s)+CO

2

(g)

Oxidation : Loss of electrons or increase in the oxidation number

C\rightarrow C^{2+}+2e^-C→C

2+

+2e

−

Reduction : Gain of electrons or decrease in the oxidation number

Pb^{2+}+2e^-\rightarrow PbPb

2+

+2e

−

→Pb

In the given balanced reaction, lead is reduced and carbon is oxidized.

Therefore, the correct option is, (b) 1 and 3
