Hint: Nuclear reactions are the reactions in which one or more nuclides are produced from the collisions of 2 atomic nuclei or one subatomic particle and an atomic nucleus .
Complete step by step solution:
There are 4 types of nuclear reactions: Fission, fusion, nuclear decay, and transmutation. The type of nuclear reaction present in the reaction given is fusion reaction. In this reaction two or more atomic nuclei combine to form a single nuclei.
Now, the mass defect is given as:
The mass of the reactant is 2*2.0141 and the mass of the product is 3.0160 + 1.0087. Substituting these values in the above equation, we get
Now, as we can see the mass defect is coming out to be positive which means that the mass of the reactant is greater than the mass of the product. This shows that some energy has been released in the reaction.
Now, we know that 1 amu = 931.5 MeV
So, now let us calculate the energy which is given by:
Also,
Therefore,
Thus, the energy released in MeV and Joules is 3.26025 MeV and Joules respectively.
Note: While calculating the quantities like energy in joules and MeV, do remember the conversion factor. Because, if you don't use the conversion factor correctly you might end up getting the wrong answers.
