Answer:
pH = 0.832
Explanation:
pH is given by the formula;
pH = - log [H+]
in this case we are given 0.147 M HCl
HCl is a strong acid and therefore completely dissociates to give out H+ ions,
Therefore; [H+] = [HCl] = 0.147 M
Hence;
pH = - log 0.147 M
<u> = 0.832 </u>
Answer:
from the way I understand the question I think the answer is (B)
Explanation:
Because the distribution into shells of oxygen is 2,6 and in sulfur is 2,8,6 and oxygen has a 8th number of electrons and sulfur has the 16th number of electrons
V = f 入 (velocity = frequency x wavelength)
<span>If we have the speed ( for wave in vacuum </span><span>i.e. 3 x 10^8 m/s) </span>
<span>Then the frequency of x-ray is </span>
<span>(3 x 10^8) ÷(1.15 x 10^-10) = 2.61 x 10^18 </span>
