  Fe₂O₃ + 3 CO   → 2 Fe + 3 CO₂

Explanation:
According to law of conservation of matter both the left hand side and right hand side shoul be having same number of elements.
The Imbalance chemical equation was as follow,

  Fe₂O₃ +  CO   →   Fe +  CO₂

L.H.S R.H.S
Fe 2 1
O 4 2
C 1 1

So, Iron being not equal were made equal by multiplying Fe by 2. Hence,

Fe₂O₃ +  CO   →   2 Fe +  CO₂

L.H.S R.H.S
Fe    2 2
O 4 2
C 1 1

Now, Oxygen is balanced by multiplying CO₂ by 2, Hence,

Fe₂O₃ +  CO   →   2 Fe +  2 CO₂

L.H.S R.H.S
Fe    2 2
O 4 4
C 1 2

Now, balancing carbon by multiplying CO by 2, hence,

Fe₂O₃ +  2 CO   →   2 Fe +  2 CO₂

L.H.S R.H.S
Fe    2 2
O 5 4
C 2 2

Again Oxygen got imbalanced, so again multiply CO₂ by 3, hence,

Fe₂O₃ +  2 CO   →   2 Fe +  3 CO₂

L.H.S R.H.S
Fe    2 2
O 5 6
C 2 3

Again Carbon got disturbed, Multiply CO by 3, hence,

Fe₂O₃ +  3 CO   →   2 Fe +  3 CO₂

L.H.S R.H.S
Fe    2 2
O 6 6
C 3 3

Thanks God! Now it is balanced. :)

Answer from: Quest

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
