Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are
important resources for a country’s energy mix, only nuclear power is
capable of producing large amounts of electricity 24 hours a day, 365
days a year.
For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC),
the U.S. Environmental Protection Agency and the U.S. departments of
Energy and Transportation—establish radiation protection regulations for
U.S. nuclear plants based on internationally recognized scientific
studies.
For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas:
reactor safety, radiation safety and security.
Atoms are made up of three basic particles: protons, electrons, and neutrons. Protons and neutrons are found in the nucleus, and the nucleus is found in the very center of an atom. Protons are positively charged whereas neutrons have no charge.
Electrons are found on the electron shells, and the electron shells are found in in the outermost region of an atom. The outermost electron shell contains valence electrons. Electrons are negatively charged.
The number of protons vary depending on the atomic number of an atom. The number of neutrons vary depending on the atomic mass and atomic number of an atom. To find the neutron you must subtract the atomic mass from the atomic number. The number of electrons in a neutral atom also vary depending on the atomic number.
Sorry this is so long. I didn't quite understand your question so I added the last paragraph in just in case it was helpful in any way. I hope I helped!
Answer:
Endothermic
Explanation:
This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.
Answer:
Solvent, substance, ordinarily a liquid, in which other materials dissolve to form a solution.
Mg = 24.3 g/mol
23.5 g / 24.3 g/mol = 0.97 mol Mg
