Proton relative mass is +1
Neutron relative mass is 0
Electron relative mass is -1
Solution :

<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the
B halides has a
than a system of
and
.
It has the same number of
, but more distinguishable kinds of
, hence, more microstates and higher entropy.
Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
