Which equation explains mass defect?
E=mc2. There is potential energy involved in a chemical reaction, or in a nuclear reaction; in both cases, less potential energy means less mass, because of the equivalence of mass and energy. (Note: In chemical reactions, the mass defect is so tiny that it is usually ignored.)
Why is mass energy not apparent for chemical reactions?
According to Einstein's equation, E = mc2, any time there is energy released by a chemical reaction there must be a change in mass. The factor, c2,is such a hugh factor that the mass change is so small that it is not measurable by our balances.
How is the low of conservation of mass related to chemical reactions?
The Law of Conservtion of Mass is essential in all chemical reactions. "related to chemical reactions" is a foolish statement, because the words are "essential", "required", and "fundamental".
What are never gained or lost in a chemical reaction?
matter is never destroyed by reactions created by chemical More specifically, both mass and energy cannot be created or destroyed in any chemical reaction, but mass and energy are equivalent under Einstein's theory of special relativity, so energy can change to mass and vice-versa in the ratio E = mc2
Is the total mass of all chemical reactions less than the total mass of the reactants?
yes!

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.
Use e equals mc2 to explain how energy is produced in fusion?
E=mc2 does not explain energy in nuclear fusion, any more than it explains energy in chemical reactions. What happens is that the forces between nucleons are extremely strong (compared to a chemical reaction, for example), the corresponding energies are big, and therefore the corresponding mass (according to the mass-energy equivalence) is measurable. There is a measurable mass deficit, and this can be used to predict the amount of energy produced.
Which laws states that mass cannot be created or destroyed?
Conservation of mass... but this has been slightly revised since. Now it is the conservation of energy. Mass can be converted to energy. In some chemical reactions in the early 20th century scientists observed that the mass of the reactants did not equal the mass of the products. This was ultimately resolved with Einstein's mass-energy equivalence formula, E = mc^2, where Eistein postulated that some rest mass was converted to energy. From this, we know that energy cannot be created or destroyed.
What did energy mass and speed of light help scientist understand?
The equivalence of energy and mass.
What happens to the total mass of substances during a chemical reaction?
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
Does a person have control of the mass-energy equivalence?
yes
Do objects lose mass as they fall due to mass energy equivalence?
No, because they do not gain energy in falling.
What did albert eistein discover?
the mass energy equivalence formula
Who discovered mass equals energy equivalence?
Albert Einstein
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.
