Answer:
5 electrons
Explanation:
Valence electrons are electrons located in the outermost energy shell, so you want to count the number of electrons in the last energy shell.
You can divide the configuration into 1s2 / 2s22p6 / 3s23p3 to see the energy shells in this atom. There are 3 shells occupied by the atom's electrons, so you need to count the electrons in the third shell as those are its valence electrons.
2 + 3 = 5 valence electrons total
Note: you don't count the 3 before the letter because that only indicates the shell level, not the number of electrons. Count only the exponents.
Through manipulation of equations, we are able to obtain the equation:
![-pOH= log [ OH^{-}]](https://tex.z-dn.net/?f=-pOH%3D%20log%20%5B%20OH%5E%7B-%7D%5D%20)
Then we can transform the equation into:
![[ OH^{-}]= 10^{-pOH}](https://tex.z-dn.net/?f=%5B%20OH%5E%7B-%7D%5D%3D%2010%5E%7B-pOH%7D%20%20)
Then we are able to plug in the pOH and directly get [OH-]:
![[ OH^{-}] = 10^{-6.48}](https://tex.z-dn.net/?f=%5B%20OH%5E%7B-%7D%5D%20%3D%2010%5E%7B-6.48%7D%20)
![[ OH^{-}]=3.31* 10^{-7} M](https://tex.z-dn.net/?f=%5B%20OH%5E%7B-%7D%5D%3D3.31%2A%2010%5E%7B-7%7D%20M%20%20)
Answer:
your quad is the top part and your hamstring is the bottom part
Explanation:
fun fact the hamstring is one of the strongest muscles in the body
The question is incomplete. But this is a typical thermodynamic problem. Looking at the given data and knowing that it is an isothermal process, the most probable question would be, the final pressure of the system. The solution is as follows:
For state 1,
PV=nRT
P₁(100 L)(1 m³/1,000 L) = (5 mol)(8.314 m³Pa/molK)(300 K)
P₁ = 124,710 Pa
For isothermal process:
P₁V₁ = P₂V₂
(124,710 Pa)(100 L)= P₂(500 L)
Solving for P₂,
<em>P₂ = 24,942 Pa</em>
Answer:
Magnetic Quantum Number
Explanation:
The quantum number that determines the orientation of orbitals in space relative to other orbitals is called the Magnetic Quantum No.
