No, actually adawadawada and awawawaw usually addawadadaw but also awawawa so it’s a possibility but very rare.
D, you can't see ultraviolet rays and other similar frequency waves with the naked eye.
Answer : The temperature in kelvins is, 
Explanation : Given,
= 178.5 KJ/mole = 178500 J/mole
= 161.0 J/mole.K
Gibbs–Helmholtz equation is :
As per question the reaction is spontaneous that means the value of 
is negative or we can say that the value of is less than zero.
The above expression will be:
Now put all the given values in this expression, we get :
Therefore, the temperature in kelvins is,
The law of conservation of mass<span> states that </span>mass<span> in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.

Answer:
If the question is which can make a buffer, then NH3, NH4Cl should be correct. Because Ammonium (NH4) is conjugate acid of NH3 so they can form an equilibrium which is basically a buffer whose purpose is to resist pH change.
Explanation:
