Explanation:
A chemical reaction equation that contains same number of atoms on both reactant and product side is known as a balanced chemical reaction equation.
For example, 
Here, number of reactant molecules are as follows.
Na = 2
S = 2
Cd = 1
O = 4
Number of product molecules are as follows.
Na = 2
S = 2
Cd = 1
O = 4
As there are already equal number of atoms on both reactant and product side. Hence, the reaction equation is balanced.
Also, in this reaction both 
and 
are present as aqueous solution. And, CdS is the precipitate that is formed as it is the insoluble solid that forms.
is present in aqueous state.

Answer: Hello your question lacks some details below is the complete question
answer :
Numerator = CH₃OH
Denominator = (CO ) ( H₂)²
Explanation:
CO + 2H₂ ⇄ CH₃OH ( formation of methanol )
hence for the equilibrium constant Kc
Numerator = CH₃OH
Denominator = (CO ) ( H₂)²
<u><em>Placing into the Bin </em></u>
Numerator : CH₃OH
Denominator : (CO ) ( H₂)²
Not Used : ( CO )² , H₂ , ( CH₃OH ) ²
