How do nuclear changes demonstrate the Law of Conservation of Mass and Energy concerning fission and fusion?
Fission and fusion involve the conversion of mass into energy, the total of which is conserved according to E = mc^2. However, at the quantum scale, which is where nuclear reactions take place, it's more accurate to view mass & energy as not two distinct concepts, but one, that of mass-energy. The "mass" of a nucleus is often slightly more than the total mass of it's constituent nucleons, with the excess being in the form of potential mass-energy from the residual strong force locking the nucleons together. In a reaction like fission or fusion, excess mass-energy locked inside the nucleus is released as radiant and kinetic energy.

What is true about all nuclear reactions?
All nuclear reactions involve changes in the structure of atomic nuclei, which can result in the release of a large amount of energy. These reactions are governed by the principles of conservation of mass and conservation of energy. Additionally, nuclear reactions can involve the splitting (fission) or combining (fusion) of atomic nuclei.
How can nuclear changes occur?
Nuclear changes can occur through processes such as fission, fusion, and decay. Fission involves splitting heavy nuclei into smaller ones, releasing energy. Fusion combines light nuclei to form heavier ones, also releasing energy. Decay involves the spontaneous transformation of unstable nuclei into more stable ones, emitting radiation in the process.
What energy comes from changes in an atom's nucleus?
Nuclear energy comes from changes in an atom's nucleus, such as nuclear fission or fusion reactions. These processes release large amounts of energy in the form of heat and radiation.
For a sustainable fission reaction each fission must produce exactly additional fission reaction(s).?
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
A nuclear reaction in which an atoms nucleus is split into two smaller nuclei and energy is released as heat is known as?
nuclear fission

What happens when the number of proton changes?
The atom is decaying, otherwise known as fission.
What are conservation laws obey in each of the nuclear reaction?
Conservation laws in nuclear reactions include conservation of mass-energy, conservation of electric charge, conservation of momentum, and conservation of lepton number. These laws dictate that the total mass-energy of particles before and after a nuclear reaction must remain constant, as well as the total charge and momentum. Lepton number conservation ensures the number of leptons (like electrons and neutrinos) remains the same throughout the reaction.
How viable is an alternative to nuclear fission and fossil fuels is to energy conservation?
Energy conservation can be a very effective way to reduce reliance on nuclear fission and fossil fuels. By reducing overall energy consumption through efficiency measures such as better insulation, efficient appliances, and transportation alternatives, the need for these energy sources can be minimized. However, some sectors may still require alternative energy sources to meet demands that conservation alone cannot fulfill.
The two processes which produce nuclear changes are?
The two processes that produce nuclear changes are nuclear fusion and nuclear fission. Nuclear fusion involves combining two atomic nuclei to form a heavier nucleus, while nuclear fission involves splitting a heavy nucleus into smaller ones. Both processes release a large amount of energy.
Where do you get nuclear fission?
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
Why do nuclear changes like nuclear fission result in such large ammounts of enegry?
This is related to the large forces between nucleons.
Prokaryotic cells reproduce by a process called?
binary fission
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
Does the mass of water change going from a liquid to a solid?
No. Mass never changes, except during nuclear fission and fusion.
How can nuclear changes occur?
Nuclear changes can occur through processes such as fission, fusion, and decay. Fission involves splitting heavy nuclei into smaller ones, releasing energy. Fusion combines light nuclei to form heavier ones, also releasing energy. Decay involves the spontaneous transformation of unstable nuclei into more stable ones, emitting radiation in the process.
Reaction that involves a change in the nucleus?
Nuclear reactions involve changes in the nucleus of an atom, such as nuclear fission (splitting of a nucleus) and nuclear fusion (combining of nuclei). These reactions release large amounts of energy and are the basis for nuclear power and weapons. The products of these reactions can be different elements and isotopes.
