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.
![l=0,1,2](https://tex.z-dn.net/?f=l%3D0%2C1%2C2)
Magnetic quantum number :
The magnetic quantum number is
![m=-2,-1,0,1,2](https://tex.z-dn.net/?f=m%3D-2%2C-1%2C0%2C1%2C2)
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

This is an incomplete question, here is a complete question.
The chemical reaction is:
![CH_4+2O_2\rightarrow CO_2+2H_2O](https://tex.z-dn.net/?f=CH_4%2B2O_2%5Crightarrow%20CO_2%2B2H_2O)
In the chemical reaction is 10 moles of H₂O are produced blank moles of CO₂ are produced.
Answer : The moles of CO₂ produced are, 5 moles.
Explanation : Given,
Moles of H₂O = 10 moles
The chemical reaction is:
![CH_4+2O_2\rightarrow CO_2+2H_2O](https://tex.z-dn.net/?f=CH_4%2B2O_2%5Crightarrow%20CO_2%2B2H_2O)
By the stoichiometry we can say that, 1 mole of CH₄ react with 2 mole of O₂ to give 1 mole of CO₂ and 2 moles of H₂O
From the balanced chemical reaction we conclude that,
As, 2 mole of H₂O produced with 1 mole of CO₂
So, 10 mole of H₂O produced with
mole of CO₂
Thus, the moles of CO₂ produced are, 5 moles.
Answer:
NH3 + HCl → NH4Cl: this equation is balanced as it has one nitrogen atom, four hydrogen atoms and one chlorine atom at each side of the equation.
Explanation:
Hello there!
In this case, according to the law of conservation of mass, we need to have the same number of atoms of each element at both sides of the equation; therefore we analyze each reaction:
NaOH + H2CO3 → Na2CO3 + H2O
: three hydrogens at the left and two at the right, so this is not balanced.
N2 + H2 → 2NH3: two hydrogens at the left and six at the right, so this is not balanced.
NH3 + HCl → NH4Cl: this equation is balanced as it has one nitrogen atom, four hydrogen atoms and one chlorine atom at each side of the equation.
AlCl3 + Li → Al + LiCl: three chlorines at the left and one of the right, so this is not balanced.
Best regards!
