Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
Magnetic quantum number :
The magnetic quantum number is
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

Answer:
d the reactant that oxidizes another atom
Explanation:
The outer planets of the solar system that are known as Gas Giants
This is an incomplete question. The complete question is:
Consider the following reaction: 2 C + D → J + 2 K .You are told that the rate of this reaction is second order overall and second order in [C]. Could any of the following be a rate-determining first step in a reaction mechanism that is consistent with the observed rate law for the reaction (note that substance Z is an intermediate)?
Answer choices
C → J + Z
C + C → K + Z
D → J + K
C + D → J + Z
Answer:
C + C → K + Z
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
given x = 2
Over all order = x+ y = 2
Thus y= 0
Thus the rate determining step must use two molecules of C as that determines the order of reaction.
The only choice that fits in is C + C → K + Z
