The correct answer is
1 and 2 only
. Fission is defined as the splitting of a nucleus into two daughter nuclei. The amount of energy produced is huge. Uranium is the primary fuel that is used in power plants.
Which of the following is true regarding nuclear fission and nuclear Weegy?
Nuclear fission involves combining elements, while
nuclear fusion involves breaking down
elements. … – is true regarding nuclear fission and nuclear fusion.
Which statement regarding nuclear fission is true?
Which statement regarding nuclear fission is true?
Fission reactions can be explained on the basis of the conservation of mass-energy
. -is true regarding nuclear fission. This answer has been confirmed as correct and helpful.
What is a fact about nuclear fission?
Nuclear fission is a nuclear process.
It is when an atom splits apart into smaller atoms
. The process gives off a lot of energy, and is used in nuclear weapons and nuclear reactors. Nuclear fission was discovered in December 1938 by the German nuclear chemist Otto Hahn and his assistant Fritz Strassmann in Berlin.
What is true regarding nuclear fission and nuclear fusion?
Both fission and fusion are
nuclear reactions that produce energy
, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Is nuclear fusion a chain process?
A chain reaction refers to a
process in
which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).
How do fission power plants work quizlet?
How does nuclear fission work in power stations?
The fuels must absorb a slow moving neutron for fission to occur
. When the atom splits, they release 2-3 more neutrons. … The heat released boils water to form steam, which turns a turbine to power a generator.
Which one of the following is a benefit associated with nuclear energy?
The advantages of nuclear energy are that it
produces low-cost energy
, it is reliable, it releases zero carbon emissions, there is a promising future for nuclear technology, and it has a high energy density.
What is a beneficial aspect of nuclear fission?
What is a beneficial aspect of nuclear fission?
The ability to absorb energy
.
The ability to release tremendous amounts of energy
.
The ability to produce more energy than nuclear fusion
.
Is salt is obtained as a reaction between?
Salt, in chemistry, substance produced by
the reaction of an acid with a base
. … The reaction between an acid and a base is called a neutralization reaction. The term salt is also used to refer specifically to common table salt, or sodium chloride.
Why nuclear energy is bad?
Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is
both expensive and dangerous
, and just because nuclear pollution is invisible doesn’t mean it’s clean. … New nuclear plants are more expensive and take longer to build than renewable energy sources like wind or solar.
Who is the world’s top producer of nuclear power?
The USA
is the world’s largest producer of nuclear power, accounting for more than 30% of worldwide nuclear generation of electricity. The country’s nuclear reactors produced 843 billion kWh in 2019, about 19% of total electrical output.
Is nuclear energy bad for the environment?
Nuclear energy produces
radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
What are control rods used for?
A rod, plate, or tube containing a material such as hafnium, boron, etc., used
to control the power of a nuclear reactor
. By absorbing neutrons, a control rod prevents the neutrons from causing further fissions.
Which of the following is the main energy source for our sun?
The sun generates energy from a process called
nuclear fusion
. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
What are the 3 steps of nuclear fusion?
- Two protons within the Sun fuse. …
- A third proton collides with the formed deuterium. …
- Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogen.
