Correct Answer is Option C i.e. <span>production of wastes needing long-term storage.
Reason:
Most of the nuclear power plant uses nuclear fission reaction for generation of electricity. In a nuclear fission reaction, a radio-active nuclei (high atomic mass) is bombarded with fast moving projectile. This results in nuclear disintegration. The mass defect between product and reactant results in generation of energy. The daughter element generated during this event, may also be radio-active in nature. These materials have extremely high half-life. Hence, this waste product needs to be stored safely for long-time so as to minimize the risk of nuclear contamination. </span>

Answer:
56.6g
Explanation:
Given that :
Mass of water, m1= 300.0 g
Temperature of water, T1= 22°C
Specific heat capacity of water, C= 4.184 J/g°C
Mass of polystyrene, m2=?
Temperature of polystyrene = 94.9
Specific heat capacity of polystyrene, c2= 1.88 J/g°C
Final temperature = 27.7 oC
Heat lost by polystyrene = Heat gained by water
mc(dT) = mc(dT)
m2 * 1.88 * (94.9 - 27.7) = 300 * 4.184 * (27.7 - 22)
m2 * 1.88*67.2 = 300*4.184*5.7
126.336 * m2 = 7154.64
m2 = 7154.64 / 126.336
m2 = 56.631838
Hence, mass of polystyrene = 56.6g
Due to the presence of three unpaired electrons, phosphorus is paramagnetic.
Electronic configuration of Phosphorus:-
[Ne] 3S2 3P3
<h3>
What determines if an element is paramagnetic or diamagnetic?</h3>
By looking at a substance's electron configuration, one can identify whether or not it has magnetic qualities. If a substance has unpaired electrons, it is paramagnetic; if all of its electrons are paired, it is diamagnetic.
<h3>P
aramagnetic:-</h3>
A tiny, positive susceptibility to magnetic fields exists in materials. When exposed to a magnetic field, these materials are only weakly drawn to it; once the external field is removed, they lose their magnetic qualities.
<h3>
Diamagnetic:-</h3>
A weak, negative sensitivity to magnetic fields exists in materials. When exposed to a magnetic field, diamagnetic materials are partially repulsed and lose their magnetic properties when the external field is removed.
