Question: Flux is often added to remove impurities from an iron ore in a blast furnace. In the reactions slag and flux are
Options:
A) $ CaSiO_3 $ and $ SiO_2 $
B) $ CaO $ and $ SiO_3 $
C) $ CaSiO_3 $ and $ CaO $
D) $ SiO_2 $ and $ CaSiO_3 $
Show Answer
Answer:
Correct Answer: C
Solution:
$ CaCO_3\to CaO+CO_2 $
$ \underset{(flux)}{\mathop{CaO}},+\underset{(impurity)}{\mathop{SiO_2}},\to \underset{(slag)}{\mathop{CaSiO_3}}, $
