Answer:
4. Principal and Azimuthal (subsidiary) quantum number
5.Principal, Azimuthal (subsidiary), and magnetic quantum number
6. 10 electrons
7. 32 electrons
8. 36 electrons
Explanation:
4. Principal and Azimuthal (subsidiary) quantum number because in 4d, 4 represent principal quantum number and d- represents azimuthal quantum number (having l- value as 3)
5.Principal, Azimuthal (subsidiary), and magnetic quantum number are the first three because 2 stands for principal, s-for azimuthal (l=0) and magnetic quantum number for s- orbital= 0
6. 10 electrons, because for sublevel with l= 3, is a d-sub-level, and d- can take 10-electrons
7. 32 electrons, using the relationship 2×n^2 for the maximum number of electrons in a shell,
,n= 4 , hence 2×4^2= 32
8. 36 electrons, because n=4 and n= 3 can have the maximum configuration of [Ar]4s^2 3d^10 4p^6 
This will sum up to 36- electrons, since Argon has 18 -electrons.
18+2+10+6=36 electrons
 
        
             
        
        
        
To calculate the <span>δ h, we must balance first the reaction: 
NO + 0.5O2 -----> NO2
Then we write all the reactions,
2O3 -----> 3O2    </span><span>δ h = -426 kj        eq. (1)
O2 -----> 2O    </span><span>δ h = 490 kj             eq. (2)
NO + O3 -----> NO2 + O2    </span><span>δ h = -200 kj          eq. (3)
We divide eq. (1) by 2, we get
</span>O3 -----> 1.5O2    δ h = -213  kj             eq. (4)
Then, we subtract eq. (3) by eq. (4) 
NO + O3 ----->  NO2 + O2   δ h = -200 kj
-       (O3 -----> 1.5 O2         δ h = -213  kj)
NO -----> NO2 - 0.5O2        δ h = 13  kj               eq. (5)
eq. (2) divided by -2. (Note: Dividing or multiplying by negative number reverses the reaction)
O -----> 0.5O2  <span>δ h = -245  kj         eq. (6)
</span>
Add eq. (6) to eq. (5), we get
NO -----> NO2 - 0.5O2        δ h = 13  kj 
+  O -----> 0.5O2                 δ h = -245  kj
NO + O ----> NO2               δ h = -232 kj
<em>ANSWER:</em> <em>NO + O ----> NO2               δ h = -232 kj</em>
