(a) Lead is getting reduced.
(b) Carbon dioxide is getting oxidized.
(c) Carbon is getting oxidized.
(d) Lead oxide is getting reduced.
(1) (a) and (b) (i) (a) and (c) (iii) (a),(b) and (c) (iv) all.​

Answer 1

carbon is getting oxidized

Answer 2

Answer:

Hey...!!

Option (iii) is correct....

Explanation:

We know

▪️If oxidation number of any number gets decreased it is said to be reduced ...

&

▪️If oxidation number of any element increases then it is said to be oxidized....

So here the equation is...

2PbO(s) + C(s) => 2Pb + CO2(g)

Checking the oxidation number of Pb...

2x - 2 = 0

x = +1 ( in reactant side )

And x = 0 ( in product side )

So oxid. number decreased from +1 to 0

Hence Lead gets reduced...

Now Checking for C....

In reactant side....

y = 0

And now in product side....

y + 2(-2) = 0

y -4 = 0

y = +4

So oxid. number increased from 0 to +4....

Hence C got oxidized....

And Hence Option (iii) is verified....
