Nuclei Test - 3...

The mass defect in a particular nuclear reaction in 0.3 grams.The amount of energy liberated in kilowatt hour is $$\left( Velocity\ of \  light=3\times { 10 }^{ 8 }m/s \right) $$

In an $$\alpha$$-decay the kinetic energy of $$\alpha$$-particle is $$48 \ MeV$$ and $$Q$$-value of the reaction is $$50\ MeV$$. The mass number of the molecular nucleus is $$X$$. Find value of $${ X }/{ 25 }$$.
(Assume that daughter nucleus is in ground state.) 

When the number of nucleons in nuclei increases, the binding energy per nucleon

The masses of neutron and proton are $$1.0087 a.m.u.$$ and $$1.0073 a.m.u. $$ respectively. If the neutrons and protons combine to form a helium nucleus (alpha particles) of mass $$4.0015 a.m.u$$, then the binding energy fo the helium nucleus will be: ($$1\ a.m.u. = 931 MeV$$)

If the total binding energies of $$_{ 1 }^{ 2 }H$$, $$_{ 2 }^{ 4 }He$$, $$_{ 26 }^{ 56 }{ Fe }$$ & $$_{ 92 }^{ 235 }{ U }$$ are $$2.22, 28.3, 492$$ and $$1786 MeV$$ respectively, identify the most stable nucleus of the following

If mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should

In the process of fission, the binding energy per nucleon

Statement-I : Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion and 
Statement-11: For heavy nuclei, binding energy per nucleon increases with increasing Z. while for light nuclei it decreases with increasing Z.      

Consider the nuclear change
$$^{237}_{93}X\, \xrightarrow{- \alpha}\, A\, \xrightarrow{- \beta}\, B\xrightarrow{- \alpha}\,C$$
Which of the following statements is not correct?

The mass of a $$^7_3Li$$ nucleus is $$0.042 u$$ less than the sum of the masses of all its nucleons. What is the binding energy per nucleon of $$^7_3Li$$ nucleus ?
