Answer:
Chlorine has higher Electron Affinity as compared to Bromine
Explanation:
Electron affinity is defined as the Potential energy change of the atom when an electron is added to a neutral gaseous atom. Therefore, more the Negative electron affinity, more favorable will be the electron addition process.
The electron affinity of Chlorine is -349kJmol^-1
The electron affinity of Bromine is -324.6KJmol^-1
This clearly shows that Chlorine is a much better Atom to be bonded with, That is the reason why in the reaction is not feasible.
→
Therefore, Chlorine has higher electron Affinity as compared to Bromine and that what makes it a much better atom to be bonded with Na. So the above reaction is not possible.

I really need the answer with all the calculation please.
Answer:
Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.
Answer:
17.03052 g/mol
Explanation:
Ammonia formula is given as NH3.
To estimate the molar mass of any compound, we have to add up the molar masses of every atom of the given compound. Ammonia comprises of one nitrogen atom and three hydrogen atoms.
So the molar mass of ammonia is
N: 14.0067 g/mol
H: 1.00794 g/mol
The molar mass of ammonia will thus be
14.0067 g/mol +3× 1.00794 g/mol =17.03052 g/mol
