Well protons and neutrons are in the center in the atom, while electrons travel in orbitals outside of the nucleus. The electric charge for protons, neutrons, and electrons are 1, 0, and -1 respectively. the mass for protons and neutrons are 1 amu (atomic mass unit) while the electron is 1/2000 amu.<span>

Answer:
B) ![k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}](https://tex.z-dn.net/?f=k_%7Bsp%7D%20%3D%5BMg_%7Baq%7D%20%5D%2A%5BOH_%7Baq%7D%5D%5E%7B2%7D)
Explanation:
Ksp is the solubility product constant.
For a generic chemical equation
![AB_{2} = A_{aq}+2B_{aq}](https://tex.z-dn.net/?f=AB_%7B2%7D%20%3D%20A_%7Baq%7D%2B2B_%7Baq%7D)
The Ksp for this generic chemical equation is
![k_{sp} =[A_{aq} ]*[B_{aq}]^{2}](https://tex.z-dn.net/?f=k_%7Bsp%7D%20%3D%5BA_%7Baq%7D%20%5D%2A%5BB_%7Baq%7D%5D%5E%7B2%7D)
So the Ksp fot the Mg(OH)2 is
![k_{sp} =[Mg_{aq} ]*[OH_{aq}]^{2}](https://tex.z-dn.net/?f=k_%7Bsp%7D%20%3D%5BMg_%7Baq%7D%20%5D%2A%5BOH_%7Baq%7D%5D%5E%7B2%7D)
Answer:
Example of a fusion dish: combination of smoked salmon wrapped in rice paper, with avocado, cucumber and crab sticks. Fusion cuisine is cuisine that combines elements of different culinary traditions that originate from different countries, regions, or cultures.
The correct answer is A) more powerful than uranium.
Radium is more powerful than uranium.
Radium is part of our environment. It's part of nature, in small amounts. It is part of the alkaline-earth group and was discovered by Pierre and Marie Curie in 1898. Although is soft it has a lot of radiation. When it is exposed to air, it quickly oxidizes. It corrodes in water because it forms radium hydroxide.
