Consider the following reaction occurring in the blast furnace: Fe ₃ O _ 4( ~s ) +4 CO _ ( g ) 3 Fe _ ( l ) +4 CO _ 2( ~g ) ' x ' kg of iron is produced when 2.32 10^3 ~kg Fe ₃ O ₄ and 2.8 10^2 ~kg CO are brought together in the furnace. The value of ' x ' is _____. (nearest integer) Given: molar mass of Fe ₃ O ₄=232 ~g ~mol ⁻¹ molar mass of CO =28 ~g ~mol ⁻¹ molar mass of . Fe =56 ~g ~mol ⁻¹

Correct answer

0

Step-by-step solution

aligned & moles of Fe ₃ O ₄= 2.32 10^3 10^3 232 =10000 ~mol & moles of CO = 2.8 10^2 10^3 28 =10000 ~mol & Fe ₃^3 O ₄+4 CO 3 Fe +4 CO ₂ & 10^4 ~mol 10^4 ~mol aligned CO is L.R. mole of Fe = 3 4 10^4 mass of Fe = 3 4 10^4 56 1000 ~kg =420 ~kg
