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 else can I help you with?
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 products are given off during a typical nuclear fission reaction?
During a nuclear fission reaction, products such as two or more lighter nuclei, neutrons, gamma rays, and energy are given off. These products can vary depending on the specific isotopes involved in the reaction.
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 element is most likely to be produced during a nuclear fusion reaction?
helium-4
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What are the subatomic articles that can change in a nuclear reaction?
The subatomic particles that can change in a nuclear reaction are protons, neutrons, and electrons. During nuclear reactions, these particles can be gained or lost, leading to the formation of different elements and isotopes.
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
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.
Does mass increase during a nuclear change?
No, mass does not increase during a nuclear change. According to the principle of mass-energy equivalence (E=mc^2), the mass of the reactants is converted into energy during a nuclear change.
The energy and particles given off during a nuclear reaction are called?
Radiation
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
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.
What products are given off during a typical nuclear fission reaction?
During a nuclear fission reaction, products such as two or more lighter nuclei, neutrons, gamma rays, and energy are given off. These products can vary depending on the specific isotopes involved in the reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
