Identify the reaction that does not take place ina blast furnace.

Answer»

`2Fe_(2)O_(3)+3Cto4Fe+3CO_(2)`
`CO_(2)+Cto2CO`
`CaCO_(3)toCaO+CO_(2)`
`CaO+SiO_(2)toCaSiO_(3)`

Solution :Blast furance is frequently used for the extraction of iron and copper from their ORES . Carbonand carbon monoxide reduce the metallic oxides to the FREE metals . Slangformation plays an important ROLE in balst furnace as it covers the melted metal and thus protects the metal from being reoxidized.
