20 B203(s) + 12180 HF(l) = 4060 BF3(g) + 609 H20(l)
Explanation:
It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.
n = l + 1
where, n = principle quantum number
l = azimuthal quantum number
Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l is 0 for s, 1 for p, 2 for d, 3 for f, and so on.
Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.
- Electronic configuration of Rb is . So here, n = 5, l = 0, m = 0 and s = ± .
- Electronic configuration of is . So here, n = 3, l = 1, m = -1, 0, +1, and s = ± .
- Electronic configuration of is . So here, n = 4, l = 2, m = -2, -1, 0, +1, +2 and s = ± .
- Electronic configuration of F is . So here, n = 2, l = 1, m = -1, 0, +1, and s = ± .
Then it is C hope it helps :)
