Why are mass energy equivalence for chemical reactions?
Mass-energy equivalence, expressed by Einstein's equation (E=mc^2), applies to chemical reactions because the energy changes involved can lead to measurable differences in mass. During a chemical reaction, bonds are broken and formed, resulting in energy release or absorption, which corresponds to a tiny change in mass. Although this mass change is usually minuscule and difficult to detect, it reinforces the principle that energy transformations are intrinsically linked to mass alterations, highlighting the fundamental relationship between mass and energy in all physical processes.
Why does an atomic bomb release more energy than a conventional chemical bomb?
An atomic bomb releases more energy than a conventional chemical bomb because the atomic bomb releases binding, or Nuclear Strong Force, energy while the conventional bomb releases chemical energy, and there is far more binding energy (hundreds and thousands of times) than there is chemical energy from the same mass of material.
How much of a difference is there between the energy released during a chemical reaction and the energy released during nuclear reactions?
Well it depends, if you had one atom of uranium and a billion tonnes of thermite, the thermite would release more. Just as a 20 megatonne nuclear bomb would release more than a few grams of sulphur and iron binding. In general though nuclear reactions release far greater amounts of energy.
What principle can be applied to all chemical reactions?
The principle of conservation of mass can be applied to all chemical reactions. It states that the total mass of the reactants must equal the total mass of the products, as no atoms are created or destroyed during a chemical reaction.
Is the total mass of all chemical reactions less than the total mass of the reactants?
No, the total mass of all chemical reactions remains constant and is equal to the total mass of the reactants. This is known as the principle of conservation of mass in chemistry. Any perceived changes in mass during a chemical reaction are due to the rearrangement of atoms, not a loss or gain of mass.
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.

What is neither created nor destroyed in ordinary chemical reactions?
chemical reactions....actually it is matter (mass)
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.
What happens to the total mass of substances during a chemical reaction?
The total mass of substances remains constant during a chemical reaction, according to the law of conservation of mass. This means that atoms are rearranged during a reaction, but no atoms are created or destroyed in the process.
Why does an atomic bomb release more energy than a conventional chemical bomb?

What happens to this lost mass?
Mass cannot be truly lost, as stated in the law of conservation of mass. It can change forms, such as being converted into energy through processes like nuclear reactions or chemical reactions. In these cases, the mass is not truly lost but rather transformed into a different state.
Give the best explanation for a gain or loss in mass?
An increase in mass is normally caused by chemical reactions with other materials, Similarly, a loss in mass can be explained by a physical change of state or by the removal of elements or compounds by chemical reactions.
How much of a difference is there between the energy released during a chemical reaction and the energy released during nuclear reactions?

Is mass a variable of potential chemical energy?
Mass is not a variable of potential chemical energy. Potential chemical energy depends on the types and arrangement of atoms in a substance, not on the mass of the substance.
Why nuclear reactions release more energy than chemical reactions?
nuclear more
When is mass converted into energy?
Mass and energy are equivalent, so there are exchanges of between mass and energy any time there is a change in motion (kinetic energy). But Atomic energy is the most familiar conversion of mass into energy. The explosion of an nuclear bomb, or the energy generated by a nuclear reactor are consequences of conversion of mass into energy. Energy from combustion is not primarily derived from mass/energy conversion, but from exothermic chemical reactions. In fact, any such exchange between mass and energy would operate in the other direction, as gasses gain mass as they are put into motion (increased kinetic energy=increased mass). But any such gain is so tiny as to be meaningless.
