Question

The energy released in the following process is:
$A+B\to C+D+Q$
(mass of A is 1.002 amu ; mass of B is 1.004 amu ; mass of C is 1.001 amu ; mass of D is 1.003 amu)
(A) 1.254 Mev
(B) 0.931 Mev
(C) 0.465 Mev
(D) 1.862 Mev

Answer 1

Hint: We know that energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another. We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. We have to solve this question based on this explanation provided above.

Complete step-by-step answer:
To answer this question, we should know that the formula that links energy and power is:
$Energy = Power \times Time$.
The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.
$\Delta m = \left[ {1.002 + 1.004 - 1.001 - 1.003} \right]$
$E = Q = 0.002 \times 931.478\;Mev$
$= 1.862Mev$


We can say that the energy that is released through a nuclear reaction or radioactive decay process. Of particular interest is the process known as fission, which occurs in a nuclear reactor and produces energy usually in the form of heat.

Hence, the correct answer is Option D.

Note: We should know that the atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as Daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
It should be known to us that scientists used carbon-12 because no other atom has exact whole-number masses in the amu scale. Also, scientists needed a pure isotope to base the system on.
