The spontaneous disintegration of a nucleus into a slightly lighter and more <u>radioactive </u>nucleus is accompanied by the emission of particles, electromagnetic radiation, or both.
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei into atomic nuclei to shape greater energetically strong atomic nuclei.
Radioactive decay is a tremendously exoergic, statistically random, first-order system that occurs with a small amount of mass being converted to strength.
Spontaneous disintegration of a radionuclide with the emission of lively particles or radiation, consisting of alpha or beta debris or gamma rays.

Answer:
15
Explanation:
Magnesium Acetate Mg(C2H3O2)2
Number of atoms:
Carbon = 4
Hydrogen = 6
Magnesium = 1
Oxygen = 4
Total = 15
Answer:
The pH of the final solution is 0.16 .
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ion concentration in a solution.
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
Concentration of HCl = 0.16 M
HCl is a string acid .1 molar of HCl gives 1 molar of of hydrogen ions.
![[H^+]=0.16 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.16%20M)
Concentration of 
= 0.52 M
Nitric is a string acid .1 molar of nitric acid gives 1 molar of of hydrogen ions.
![[H^+]'=0.52 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%27%3D0.52%20M)
Total hydrogen ion concentration:
![[H^+]''=[H^+]+[H^+]'](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%27%27%3D%5BH%5E%2B%5D%2B%5BH%5E%2B%5D%27)
=0.16 M+0.52 M=0.68 M
The pH of the solution:
![\pH=-\log[H^+]''=-\log[0.68 M]](https://tex.z-dn.net/?f=%5CpH%3D-%5Clog%5BH%5E%2B%5D%27%27%3D-%5Clog%5B0.68%20M%5D)
pH = 0.16
The pH of the final solution is 0.16 .
When blowing on the sand, it will make a sort of like mountain but this is known as a dune. The air blows the sand to create a dune.
