Red hot iron absorbs $\mathrm{SO}_2$ giving the product

A
$\mathrm{FeS}+\mathrm{O}_2$
B
$\mathrm{Fe}_2 \mathrm{O}_3+\mathrm{FeS}$
Correct answer
C
$\mathrm{FeO}+\mathrm{FeS}$
D
$\mathrm{FeO}+\mathrm{S}$

Solution

It is the oxidation process. $3 \mathrm{Fe}+\mathrm{SO}_2 \longrightarrow 2 \mathrm{FeO}+\mathrm{FeS}$
Fe is oxidised to form FeO and FeS .

Hence, the correct answer is option: 'C'.
