Answer:
activity coefficient
activity coefficient
The change in pH in part A = 0.092
The change in pH in part B = 0.102
Explanation:
From the given information:
pH of HCl solution = 1.092
Activity of the pH solution [a] =
[a] = 0.0809 M
Recall that [a] = × C
where;
= activity coefficient
C = concentration
Making the activity coefficient the subject of the formula, we have:
B.
The pH of a solution of HCl and KCl = 2.102
[a] =
[a] = 0.00791 M
activity coefficient
C. The change in pH in part A = 1.091 - 1.0 = 0.092
The change in pH in part B = 2.102 -2.00 = 0.102
The model would look something like the image below.
There would be a <em>central nucleus</em> containing <em>20 protons</em> and <em>20 neutrons</em>.
Surrounding the nucleus would be four concentric rings (energy levels) containing <em>20 electron</em>s.
Going out from the nucleus, the number of electrons in each ring would
be <em>2, 8, 8, 2</em>.
