Answer:
chain reaction
Explanation:
The description is termed a chain reaction.
During nuclear fission, a heavy radioactive isotope disintegrates rapidly into two lighter nuclei and several neutrons with the release of large amount of energy.
Each of the neutrons produced can now react with the new radionuclide to produce another new set of nuclide thereby releasing energy and several neutrons. This is called a chain reaction.
For the nuclide described above, we can express as:
²³⁶₉₂U → fission fragments(²³⁵₉₂U) + neutrons + energy
fission with the neutrons:
²³⁵₉₂U → ²³⁶₉₂U ..................................
Increases mass by 1 amu. Neutrons have mass.
Answer:
B one mole of carbon is lighter than one mole of magnesium
Hi! My answer would be D, USA.
Explanation:
We are provided with 5 pieces of an address. They are as followed.
12 Riverdale Lane, Apartment A, San Jose, California, and USA.
Imagine each of the five parts of Beck's address represents Earth, the Milky Way, the moon, the solar system, or the universe, based on their sizes. Which of the following parts of Beck's address would represent the solar system?
If we have to plug in Earth, the Milky Way, the moon, the solar system, and the universe, (all based on size,) we would first start with what "Apartment A" would be in this scenario. Apartment A is the smallest piece we have to work with, and so is the moon. This leads me to believe that the Moon should be plugged into Apartment A. Now, 12 Riverdale Lane is most likely going to be the Earth, since it is the second smallest one on our list. San Jose would turn into the Sun, California represents the Milky Way, and USA represents the solar system.
I sincerely hope I helped!
Have a wonderful day :)

Answer:
Option C is correct.
The minimum amount of material that is needed for a fission reaction to keep going is called the critical mass.
Explanation:
Nuclear fission is the term used to describe the breakdown of the nucleus of a parent isotope into daughter nuclei.
Normally, the initial energy supplied for nuclear fission is the energy to initiate the first breakdown of the first set of radioactive isotopes that breakdown. Once that happens, the energy released from the first breakdown is enough to drive further breakdown of numerous isotopas in a manner that leads to more energy generation.
But, for this to be able to be sustained and not fizzle out, a particular amount of radioactive material to undergo nuclear fission must be present. This particular amount is termed 'critical mass'
Hope this Helps!!!
