In the manufacture of iron in the blast furnace, iron (lll) oxide is mixed with coke and limestone, and different reactions occur in the process. Which of the following statements is true with respect to these reactions?
the coke is a powerful reducing agent and easily converts the iron oxide to iron
the calcuim carbonate reacts with SiO2 an earthly impurity in the ore, to from calcuim silicate
the coke will react with the iron produced to form steel
all the carbondioxide required in the process comes from the decomposition of the calcium carbonate
the calcium carbonate decomposes to give calcium oxide, which then forms calcium silicate with the earthly impurity

E is the correct answer. This is how it is obtained:
B is wrong, because CALCIUM OXIDE formed from the decomposition of CaCO3 reacts with SiO2 to give calcium trioxosilicate(IV), not CaCO3.
C is wrong, because the process is used to manufacture IRON and not steel.
A is wrong, as the main reducing agent is CARBON MONOXIDE and not coke.
D is also wrong for the same reason.
Leaving us with E.
Myschool is wrong here
Formation of steel is not part of the process needed for the manufacture of Iron
So the correct option is C
