Each reation releases or absorbs a very large amount of energy per atom.

Answer: Option (D) is the correct answer.
Explanation:
A chemical reaction is defined as a reaction that involves exchange of electrons between the combining atoms. Not every chemical reaction releases or absorbs a very large amount of energy per atom.
On the other hand, a reaction that involves change in atomic nuclei of an atom either by splitting or combining of two atomic nuclei is known as a nuclear reaction.
For example,
Nuclear fission is a reaction in which a large nucleus splits by absorption of energy into two atomic nuclei. Nuclear fusion is a reaction in which two atomic nuclei combine together to result in the formation of a large atomic nuclei along with release of energy.
Each nuclear reaction releases or absorbs a very large amount of energy per atom.
Therefore, we can conclude that each nuclear reaction releases or absorbs a very large amount of energy per atom.

Solution:
Reduction potential of metal ions are provided below. Higher the value to reduction potential, greater is the tendency of metal to remain in reduced state.
In present case, reduction potential of Au is maximum, hence it is least prone to undergo oxidation. Hence, it is least reactive.
On other hand, reduction potential of Na is minimum, hence it is most prone to undergo oxidation. Hence, it is most reactive.

Answer:
of
is 0.0513
Explanation:
Solubility equilibrium of :
Solubility product of (
) is written as-
Where and
represents equilibrium concentration (in molarity) of
and
respectively.
Molar mass of = 183.48 g/mol
So, solubility of =
= 0.234M
1 mol of gives 1 mol of
and 2 moles of
upon dissociation.
so, = 0.234 M and
=
so,
