Answer: Option (D) is the correct answer.
Explanation:
Molecules are defined as the substances which contain same type of elements which are chemically combined to each other.
For example, is a molecule which contains two same atoms that is, chlorine atoms.
In this molecule, the atoms are chemically combined together due to sharing of electrons. Hence, they tend to form covalent bonds.
Therefore, we can conclude that molecules are different from atoms because they contain chemical bonds.

Answer:
Explanation:
For a chemical reaction, equilibrium is a state at which the rate of the forward reaction equals that of the reverse reaction. The equilibrium constant Keq is a parameter characteristic of this state which is expressed as a ratio of the concentration of the products to that of the reactants.
For a hypothetical reaction:
xA + yB ⇄ zC
The equilibrium constant is :
The given reaction involves the decomposition of H2O into H2 and O2
The equilibrium constant is expressed as :
Since Keq = 5.31*10^-10
