What quantities do not change during a nuclear reaction?
If you consider the equation, E=mc2, you can see that an amount of mass can be considered as equal to an amount of energy. In other words, we could take all the mass in a nuclear reaction and figure out how much energy that represents. If you add that to the amount of energy present at the same time, you get a summation of energy (some of which is mass represented as energy). That amount of energy does not change in a nuclear reaction.
What parts of an atom can change during a nuclear reaction that can't change in a chemical reaction?
the number of protons and neutrons
What element is most likely to be produced during a nuclear fusion reaction?
helium-4
How does an isotope of an element change during nuclear decay?
During nuclear decay, radioisotopes of one element can change into one or more isotopes of a different element altogether.
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.

What is changed during a nuclear reaction in the sun?
atoms
During nuclear reaction two protons change into what?
In the nuclear fusion process in the sun, two protons change into a proton and a neutron, plus also a positron and a neutrino. This is part of the synthesis of helium and release of energy which powers the sun. You can see the complete chain of reaction at the link below
Does temperature change during a nuclear reaction?
Yes. Very much. That is how we get useful heat to make steam, to turn turbines, to make electricity.
What is necessary sustain a nuclear chain reaction?
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.
What colour dous it change to during the reaction?
what colour change occurs during the calcium and hydrochloric acid reaction
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
The subatonic particles released during a nuclear chain reaction are what?
subatonic particles
During the solar nuclear reaction what four nuclei bond together?
hydrogen
Can a material change from one substance to another during a chemical reaction?
"Substance" is too fuzzy a word. Chemical reactions can change materials into other compounds, for example shiny iron into rust (Fe2O3). But it cannot change an element into another element. A nuclear reaction can do that, for example uranium into plutonium.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
