Which is the next logical step in balancing the given equation? 3co(g) + fe2o3(s) fe(s) + 3co2(g)
a. place the coefficient 2 in front of iron(iii) oxide.
b. leave it alone, as it is already balanced.
c. place the coefficient 2 in front of elemental iron.
d. replace the coefficient 3 in carbon monoxide with 6.

Answer : The correct option is, (C) Place the coefficient 2 in front of elemental iron.

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

The given unbalanced chemical reaction is,

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of iron are not balanced while all the atoms are balanced.

In order to balanced the chemical reaction, the coefficient 2 is put before the 'Fe'.

Thus, the balanced chemical reaction will be,

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.
