M=147/9 x8 m=15kg
The mass of falling rock is 15kg.
Answer:

Explanation:
Assume Ksp of
=
( it is general value ,i took it because not given in question)
molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.
Ksp=solubility product;

Lets molar solubilty of
is S then
![[Pb^{+2}]=S;](https://tex.z-dn.net/?f=%5BPb%5E%7B%2B2%7D%5D%3DS%3B)
![[SCN^{-1} ]=2S;](https://tex.z-dn.net/?f=%5BSCN%5E%7B-1%7D%20%5D%3D2S%3B)



Answer:
Cobalt/Electron configuration
Explanation:
[Ar] 3d7 4s2
Here, the three different notation of the p-orbital in different sub-level have to generate
The value of azimuthal quantum number (l) for -p orbital is 1. We know that the magnetic quantum number
depends upon the value of l, which are -l to +l.
Thus for p-orbital the possible magnetic quantum numbers are- -1, 0, +1. So there will be three orbitals for p orbitals, which are designated as
,
and
in space.
The three p-orbital can be distinguish by the quantum numbers as-
For 2p orbitals (principal quantum number is 2)
1) n = 2, l = 1, m = -1
2) n = 2, l = 1, m = 0
3) n = 2, l = 1, m = +1
Thus the notation of different p-orbitals in the sub level are determined.
