Answer:
So, only one electron is there with n = 0, l = 0 and its quantum set is n = 0, l = 0, ml = 0, ms = -1/2. Hope, this is helping. The maximum number of electrons that can fit inside a 'n' shell is 2n^2. So it would be 1.

Answer:
Final pH of the solution = 5.46
Explanation:
The detailed step is shown in the attachment.
The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few
relationships between [H+] and [OH−]
ions. And because there is a large range of number between 10 to 10-15
M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+
][OH- ] = 10-14. From here we can derive the values of each concentration.
-log[H+ ] + -log[OH- ] = -log[10-14]
pH + pOH = 14
So pH = 14 – pOH and pOH = 14 –
pH
Answer:
1.35 moles
Explanation:
Calculate how many
of potassium (K) are present in a sample of 8.12x10^23 atoms of K
6.02 X 10^23 atoms are 1 mole. how many 6.02 X 10^23 are in
8.12 X 10^23
divide 8.12 X 10^23 into sets of 6.02 X 10^23
(8.12 X 10^23)/(6.02 X 10^23) =1.35 moles
