*A & B*
Answers A & B are not possible, as Hydrogen “bonds” are intermolecular forces and do not actually involve transfer or sharing of electrons.
*C & D*
Viscosity and surface tension are not the answer as they are not specific enough to the question.
*E*
Polarity of water molecules is the correct answer, as water molecules are highly polar. The partial positive of the Hydrogen on one water molecule is highly attracted to the partial negative of the Oxygen (due to its lone pairs) on another water molecule.
Answer is 38/3 or 12.67
3x=38
x=38/3
therefore answer is the one mentioned above
Explanation:
Chemical reaction equation for the give decomposition of 
is as follows:.
And, initially only is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,
= 0.23 aatm
So, = 2.3 - 2(0.23)
= 1.84 atm
Now, expression for 
will be as follows.
= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is 
.
