Einstein deduced that mass and energy are equivalent, and that E = mc2 where E = energy, m = mass, c = velocity of light. This of course applies to the actual amount of mass destroyed in a reaction, not to the total masses involved. Thus in a nuclear fission reaction in U-235, only a small amount of the total mass of the U-235 nucleus disappears to form energy, most of it appears in the masses of the two fission fragments, the total energy released is 200 Mev per fission which is about 3 x 10-11 Joules. In a chemical reaction energy is released but at a much smaller proportion of the masses involved. Bearing this in mind you can see that the total energy in objects around us is truly awesome! You can work out some figures, use kilograms for mass and meters/sec for c, E will then be in Joules.

How much energy is contained in matter with a mass of 2 grams?

Why is atomic energy dangerous?
Atomic energy can be dangerous due to the potential for accidents at nuclear power plants, which can lead to environmental contamination and health risks. Additionally, the radioactive waste produced by nuclear reactions poses a long-term threat to health and the environment if not properly contained and managed.
How nuclear technologies produce enermouse amount of energy?
Nuclear technologies produce enormous amounts of energy through a process called nuclear fission, where the nucleus of an atom is split to release large amounts of heat. This heat is then used to generate steam, which drives turbines connected to generators that produce electricity. The energy released in nuclear reactions is much greater than in chemical reactions, leading to the large amounts of energy produced by nuclear power plants.
Does nuclear fusion produce much less energy per atom than nuclear fission?
In terms of energy per atom, nuclear fusion produces more energy than nuclear fission. Fusion reactions involve the combination of lighter atomic nuclei to form heavier nuclei, releasing large amounts of energy in the process. Fission reactions, on the other hand, involve the splitting of heavier atomic nuclei into smaller fragments, releasing energy.
What are the bad things about nuclear fission?
Some potential drawbacks of nuclear fission include the generation of radioactive waste that requires long-term storage, the risk of nuclear accidents such as meltdowns, the proliferation of nuclear weapons material, and the high cost of building and maintaining nuclear power plants.
How much energy is contained in a lightning bolt in joules?
The energy contained in a lightning bolt is typically around 1 billion joules.
How much of Colorado's energy is nuclear?
There are no nuclear generating plants in Colorado
Advantage and disadvantage of nuclear energy?
disad: very toxic waste that if not contained can cause a lot of damage and spread (ie chernobyl) adv: these days waste is contained in state of the art sealed containers and does not otherwise harm anyone. also a small amount of matter creates a large amount of energy... so there is little fear that we will run out of it
How does nuclear energy impact the environment?
Not much pollution unless there is a nuclear reaction.
How much nuclear energy is used in Indiana?
Indiana has no nuclear power plants.
How much energy is contained within the universe?
The total energy contained within the universe is not precisely known, but it is believed to be a vast amount that includes both matter and dark energy.
What other names are there for nuclear energy?
Other names for nuclear energy include atomic energy, nuclear power, and atomic power.

Yes much less

Convert chemical energy into nuclear energy?
Chemical energy can be converted into nuclear energy through processes like nuclear fission or fusion. In nuclear fission, the nucleus of an atom is split into smaller parts, releasing a significant amount of energy. In nuclear fusion, nuclei are combined to form heavier nuclei, also releasing energy. These processes release a much larger amount of energy compared to chemical reactions.
