Maximum number of electrons in nth energy level
Now
Max electrons
Answer:
my probably best answer is B
Answer:
V₂ = 2.91 L
Explanation:
Given data:
Initial volume = 3.50 L
Initial temperature = 90.0°C (90+273 = 363 K)
Final temperature = 30.0 °C ( 30 +273 = 303 K)
Final volume = ?
Solution:
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
V₁/T₁ = V₂/T₂
3.50 L / 363 K) = V₂ / 303 K)
V₂ = 0.0096 L/K × 303 K
V₂ = 2.91 L
Answer:
The correct answer is option B
B. In a sample of enriched uranium
Explanation:
Nuclear fission is a nuclear reaction whereby large nucleus of an atom is break down into smaller parts lighter nuclei or daughter nuclei and release large amount of energy, due to the large amount of energy there are alot of heat released.
During the process large nucleous is bombarded by the neutrons, as a result of this the nucleous becomes disintegrated because it's unstable and their is production of lighter nuclei as well as neutrons and energy.
When the U -235 particles are compacted together there result a high energy neutron which can bombard another Uranium - 235 molecule in the region. uranium is enriched with more of the fissile uranium isotope, then when it is enriched it can be used to make atomic reactors and explosives like bombs.
