Answer:

The electron spin can only take place in opposite directions.

Explanation:

The angular momentum of a quantum number deals with the shape of the atomic orbital. Each orbital has a specific shape. In addition, the electrons have specific spin directions. let's say a quantum number, m is having two three shells. It means that:

number of shells, n = 3.

The level will be 3

the possible spins will be 0, 1, 2.

This takes place in the negative direction as well to give:

-2 , -1, 0, 1, 2

Thus, 3,2,-3,+1/2 cannot be a quantum number as it does not have a equal and opposite spin.

L = an integer from 0 to n-1
mL = an integer from -L to +L 
ms = + or - 1/2 

the format is (n, L, mL, ms) 

so your 
n = 3... this is OK 
L = 2.. also OK.. if n=3, L can = 0, 1, or 2 
mL = -3 is NOT ok... if L=2.. mL can only be -2, -1, 0, +1, or +2 
ms = +1/2 and that is ok

Hope this helps!

Why B-Cl bond is polar?

aniked [119]

Answer:

The difference in the electronegativities of chlorine and boron is 3.0 - 2.0 = 1.0 ; the difference in between chlorine and carbon is 3.0 = 2.5 = 0.5 . Consequently, the B-Cl bond is more polar ; the chlorine atom asrries the partial negative charge because it has higher electronegativity .

Write a balanced half-reaction for the product that forms at each electrode in the aqueous electrolysis of the following salts:(

likoan [24]

Balanced Half reactions are:

At anode 2 $Cl^{-}$ ==> Cl₂+ $2e^{-}$ + H₂O ==> $ClO^{-}$ + 2 $H^{+}$ + $Cl^{-}$

At Cathode: 2 $H^{+}$ + $2e^{-}$ ==> H₂

Since the question states that you are using an aqueous solution of MnCl₂, so ions will have present are, H₂O, $H^{+}$ , $Mn^{2+}$ and $Cl^{-}$

Now at Anode reaction will occur as given:

2 $Cl^{-}$ ==> Cl₂+ $2e^{-}$ + H₂O ==> $ClO^{-}$ + 2 $H^{+}$ + $Cl^{-}$ (will occur)

At Cathode:

2 $H^{+}$ + $2e^{-}$ ==> H₂ (will occur)

At Cathode:

$Mn^{2+}$ + $2e^{-}$ ==> Mn (This reaction will not occur)

The deposition of solid Mn will not occur because in aqueous solution, $H^{+}$ will be reduced before $Mn^{2+}$ .

The reduction potentials for $H^{+}$ is zero whereas reduction potential for $Mn^{2+}$ is - 1.18V.

The reduction potential of a species is its tendency to gain electrons and get reduced. It is measured in millivolts or volts. Larger positive values of reduction potential are indicative of a greater tendency to get reduced.
