Answer:
c. isotope number
Explanation:
Mass Number is the sum total of mass of protons and neutrons present in the nucleus of an atom. Generally they are being used in distinguishing isotopes. E.g Carbon - 12, Carbon - 13
Atomic Number is the number of protons. Every single element has it's unique atomic number and can be used in identification purpose. E.g Carbon - 6, Hydrogen - 1.
The correct option is option C. This is the symbol that is not necessary for the identification of a nuclide.

Answer:
In the chemical bonds.
Explanation:
There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.
Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.

<span>To
solve this we assume that the gas is an ideal gas. Then, we can use the ideal
gas equation which is expressed as PV = nRT. At number of moles the value of PV/T is equal to some constant. At another
set of condition of temperature, the constant is still the same. Calculations
are as follows:</span>
P1V1/T1 = P2V2/T2
P1 = P2V2T1/T2V1
P1 = (114)(1.32)(596)/(715)(.654)
P1 = 191.80 kPa
