What do nuclear reactions convert into energy?
The nuclear reactions result in mass loss (or mass defect) that transforms into energy according to formula: E = mc2 , wher c is the light
Why nuclear reactions release more energy than chemical reactions?
nuclear more
In nuclear reactions what is converted into energy?
Mass is destroyed, releasing energy, E = mc2
Why does the mass stay the same when hydrogen burns in oxygen and water is made?
Law of conservation of mass: total mass of Reactants AND Products stays UNCHANGED during ANY reaction (except nuclear reactions like fusions)
Why are the products of nuclear fusion slightly less massive than the reactions?
The products of nuclear fusion are slightly less massive than the mass of the reactants because some of the mass of the reactants is converted into nuclear binding energy to hold the fusion product together.
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.
Does atomic mass stay the same?
The atomic mass of a radioactive atoms is changed during the radioactive decay (alpha decay, neutron decay, proton decay, double proton decay), spontaneous or artificial fission, nuclear reactions.
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.
Which of the following are differences between nuclear reactors and nuclear bombs?
-both have critical mass -both use chain reactions A P E X renaa
A mass of gas in space made hot by nuclear reactions?
A 'proplid', or a proto-stellar object, often called a proto-star, and some believe (as I do) that 'Herbig-Haro Objects', are newly formed stars. At any rate, a star is a mass of gas in space made hot by nuclear reactions.
What is the best place to be during a nuclear attack?
In a mass shelter.
Can you convert energy in to mass or mass into energy?
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
