It is possible to make a model of a fission chain reaction with mousetraps and table tennis balls, with the balls placed on an a
rmed trap. Which statement best explains why this is a good model?
1 answer:
Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.

Explanation:
10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.
11) The bombardment of U-235 with neutrons leads to the reaction;
Hence
a = 92, b= 95, c= 53
12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.
Hence;
