Question

1. Which of the statements about the reaction below are incorrect?

2PbO(s)+C(s) 2Pb(s)+CO 2 (g)

dal Lead is getting reduced.

(6)

Carbon dioxide is getting oxidised.

(a), (b) and (c)

(iv) all

(ii) (a) and (c)

1) (a) and (b)

(d) Lead oxide is getting reduced.

(c) Carbon is getting oxidised.

Answer 1

Answer:

1) (a) and (b

Explanation:

In PbO, the Oxidation state of Pb is +2. In Pb, it's 0. Implies PbO reduces to P

The oxidation state of carbon in C(free carbon) is 0, in CO2 it's +4. Implies C oxidizes to CO2
