Why does not law of conservation of energy apply to the nuclear reactions?

A percentage of the matter is liberated as energy. Fusion reactions tend to convert more mass to energy than do fission reactions.
Proton and neutron counts are preserved, but the mass of a helium nucleus is less than the rest mass of the particles of which it is comprised--two neutrons and two protons. The difference is known as the "mass defect," and is equivalent to the energy released in a fusion reaction. Similarly, fission reactions (the splitting apart of atomic nuclei) also liberates energy in a variety of forms.
Note: Mass/Energy is conserved in ANY reaction. But as mass may be converted into energy, and vice versa, the mass itself is not necessarily conserved.

∙ 13y agoIn both fission and fusion nuclear reactions where the net result is lower mass, the lost mass is converted directly to energy. The amount of energy created can be found with Einstein's famous E=MC^2 equation, where M is the difference in mass before and after the reaction.

particles of elements break down or combine releasing huge amount of energy as the energy mass equivalence theorem says energy=mass* speed of light *speed of light,which states the energy released = matter destroyed.

The law of conservation of mass is apply to chemical changes?
The law of conservation of mass applies to all chemical reactions with the exception of nuclear reactions. In nuclear reactions, mass is converted to energy to vice versa. Thus, the law of conservation of mass does not apply in these cases.
In what situations does the law of conservation of energy not apply?
In general Conservation of Energy does not hold internal to a system, it only holds at the boundary of the system. This is where the limits of the system are. Internal to the system energy is not conserved. The situations where the Conservation does not apply is where the force is not zero or the first derivative of energy is not zero.
How does the of the conservative of mass apply to chemical reactions?
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
Who said Matter is neither created nor destroyed in chemical reactions?
The law of conservation of mass (matter is neither created nor destroyed) was first clearly formulated by Antoine Lavoisier in 1789. However, Mikhail Lomonosov (1748) had previously expressed similar ideas and proved them in experiments.
What is conserved during any change color volume identity or mass?
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
The law of conservation of mass is apply to chemical changes?
The law of conservation of mass applies to all chemical reactions with the exception of nuclear reactions. In nuclear reactions, mass is converted to energy to vice versa. Thus, the law of conservation of mass does not apply in these cases.
How does the law of conservation of energy apply to nuclear energy?
Before the reaction, the energy exists as potential energy, caused by the nuclear forces. After the reaction, the energy goes away as gamma rays for example, which may eventually be absorbed and get converted to heat.
How does the law of conservation not apply to the energy of stars?
conservation laws do apply to stars, as mass/energy is conserved by the formula E(energy) = M(mass) x C squared (speed of light), this happens as a nuclear fusion reaction when the hydrogen molecules in the stars and fused to make Helium, some mass is lost (converted to energy). cheers
Where does the law of conservation of energy apply?
Everywhere.
How does nuclear energy relate to the sun?
We derive electromagnetic energy from the nuclear fusion reactions on the sun. We also apply nuclear energy (fission) on earth to generate lots of thermal energy, which we use in a steam cycle to generate lots of electric power.
Which of the conservation law does not apply to an inelastic collision?
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
How does the law of the conservation of mass apply to to chemical reactions?
Atoms cannot be added or lost in a chemical reaction.
Can the law of conservation of mass ever be absolutely proven to be true?
Scientists have already found that the law of conservation of mass is not absolutely true in all cases. Albert Einstein's famous equation, e = mc2 describes the amount of energy that can be created by transforming mass into energy, a process which happens in nuclear reactors or nuclear bombs, as well as in the sun (which could be considered a natural nuclear reactor). Aside from that, there are other situations in which even the broader rule of conservation of mass-energy does not apply. Virtual particals appear and disappear in violation of conservaton of mass-energy. So there are various exceptions. But in certain well defined circumstances, conservation of mass has been observed to be quite reliable.

How does the law of conservation of energy apply to the coal power plant?
the power plant is hazardous to the enviroment.
How does the of the conservative of mass apply to chemical reactions?
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
