Which of the following arrangements is possible?
n | l | m | s |
5 | 2 | 2 |
n | l | m | s |
2 | 2 | 0 |
n | l | m | s |
3 | -2 | 1 |
n | l | m | s |
0 | 0 | 1 |
A.
n | l | m | s |
5 | 2 | 2 |
When n = 5, then l = 0, 1,2, 3, 4.
Again when l =2, then m = -2, -1, 0, +1, +2.
The 's' value can be 1/2. Hence the arrangement, n =5, l= 2, m=2, s=1/2 is possible for an electron.
When the temperature of reactions will increase then the effect on pH value will
increase
decrease
first increases then decreases
remains same.
The pH of aqueous solution ofammonium formate is (pKa of HCOOH = 3.8 and pKb of NH3= 4.8)
7
6.0
6.5
8.9
