The highest value of the ion is the nucleon number. The correct option is a.
<h3>What is nucleon number?</h3>
The mass number of an element is so named because it represents the total number of protons and neutrons in the element.
The total number of protons and neutrons in an atomic nucleus is known as the mass number, also known as the atomic mass number or nucleon number. It is roughly equivalent to the atomic mass expressed in atomic mass units.
In the given ion Q+, the nucleon number has the highest value in the ion
Thus, the correct option is a.

Answer:
answer in the picture above
Explanation:
It is given that the energy change is -162 kJ and work done is -194 kJ. As we know that formula for change in enthalpy is as follows.
dH = dE + W
where, dH = change in enthalpy
dE = change in energy
W = work done
Therefore, the change in enthalpy will be as follows.
dH = dE + W
= -162 kJ + (-194 kJ)
= -356 kJ
As the negative sign indicates heat is being released. Therefore, the reaction is exothermic in nature.
Thus, we can conclude that the change in energy of the gas mixture during the reaction is -356 kJ.
