Question

Among the reactions (a) - (d), the reaction(s) that does/do not occur in the blast furnace during the extraction of iron is /are :
$\left(a\right)CaO+Si{O}_2\to CaSi{O}_3$
$\left(b\right)3F{e}_2{O}_3+CO\to 2F{e}_3{O}_4+C{O}_2$
$\left(c\right)FeO+Si{O}_2\to FeSi{O}_3$
$\left(d\right)FeO\to Fe+\frac{1}{2}{O}_2$

• A. (c) and (d )
• B. (a)
• C. (a) and (d)
• D. (d)

Answer 1

Answer: (A)

In blast furnace (metallugy of iron) involved reactions are
(a) $CaO+Si{O}_2⟶CaSi{O}_3$
(b) $3F{e}_2{O}_3+CO⟶2F{e}_3{O}_4+C{O}_2$
