It is often stated that mass is transformed to energy. This is wrong, since both mass and energy are conserved in a chemical reaction - or in a nuclear reaction. The Wikipedia article on "binding energy" clarifies this.

What is the reaction of nuclear fusion?

Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass.


What happens to some of the mass in a nuclear reaction like fusion?

it fusions


In a nuclear fusion reaction the mass of the products is?

Less than 1%.


In a nuclear fusion reaction how does the mass of the products compare to the mass of the reactants.?

In a nuclear fusion reaction, the mass of the products is slightly less than the mass of the reactants. This loss of mass is converted into energy according to Einstein's E=mc^2 equation. The difference in mass is known as the mass defect.


In a nuclear reaction mass must be a lost to produce energy?

The mass is not lost but transformed in energy.


In nuclear fusion mass transforms into what?

In nuclear fusion mass transforms into energy.


What happens to mass in a nuclear fusion reaction?

If you talk about fission reaction (current nuclear power plants) then the mass is turned into energy, mostly in a form of heat, that is then turned to make energy in a massive closed system steam turbines plant.If you really mean Fusion reaction (humans not able to replicate such, but such is known to happen in stars), then there are no missing mass.


Is the total mass after fusion greater or less than before fusion?

The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.


How is energy created from nuclear energy as per the first law of thermodynamics?

The first law of thermodynamics states that energy can be transformed, but not created nor destroyed. In a nuclear reaction, mass is transformed into energy.


Type of reaction in which mass is transformed into energy?

Mass can be conveted into energy by a nuclear reaction. The ammount of energy converted can be calculated by E=mc^2. So for every gram that is lost 9,000,000,000,000,000 J of energy will be released. That is enough to power a 100 Watt light bulb for 3 million years. That's a lot of energy.


What happens to the mass lost in nuclear fusion?

The mass lost in nuclear fusion is converted into energy according to Einstein's famous equation, E=mc^2. This energy is released in the form of photons, such as gamma rays, and contributes to sustaining the fusion reaction.


What is a type of nuclear reaction produced in the sun?

The primary nuclear reaction in the sun is the fusion of hydrogen nuclei (protons) to form helium nuclei, releasing energy in the form of gamma rays and heat. This process, known as the proton-proton chain reaction, powers the sun by converting mass into energy through nuclear fusion.
