How many moles of Li3N will be created using 0.24 moles of Li in the given reaction? 6Li + N2 2Li3N
andreyandreev [35.5K]
6 Li + N2 =  2 Li3N

6 moles Li ---------> 2 moles Li3N
0.24 moles Li ------>  ?

moles Li3N =  0.24 * 2 /  6

=  0.48 / 6 

= 0.08 moles of li3N

hope this helps!.

The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:
Lera25 [3.4K]

The allowable combination for the atomic orbital is n=4, l=2, m_{l}=2.

<h3>What are the three quantum numbers of an atomic orbital?</h3>

Three quantum numbers specify an atomic orbital:

- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.

- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),

- $\boldsymbol{m}_{l}$ is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus; m_{l} values are integers from -l to =l(l limits ml)

For n = 4, l can four values: 0, 1, 2, and 3. To be consistent with m_{l}=+2the l value must be higher than 1. There are two l values that are consistent with n and m_{l} values:  l= 2 or 3

Therefore, the allowable condition is n=4, l=2, m_{l}=2
