Answer:

Explanation:
The computation is shown below:
Data provided in the question
The frequency of the radio wave is f = 
Let us assume the number of photons is N 
= 
And, h = 
Based on the above information, the total energy is
As we know that
E = N h f


We just applied the above formula so that the total energy contained could come i.e by multiplying the three items so that the correct value could come
C bc it only has red in it
It will go over the amount it needs to.
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.
