Answer:
B
Explanation:
Atomic # = Protons
it says 4 p in the inside of the orbital
Answer:
Lake and River pollution?
Explanation:
As,
Kw = [H+] [OH-]
For water, [H+] = [OH-]
Therefore we can write
Kw = [H+]²
9.311 × 10-14 = [H+]²
[H+] =
3.04 × 10-7 = [OH-]
Ph = - log [H+]
= - log (
3.04 × 10-7)
= 6.52
Thus, Ph = PoH = 6.52
