Hello there!
In this case, since the chemical equation representing the neutralization of the weak base quinine can be written as follows:
Whereas we have 0.100 moles of the base and those of acid as shown below
Which means that the remaining moles of quinine are:
And the resulting concentration:
Now, the calculation of the pH requires the pKb of quinine (5.1) as its ionization in water produces OH- ions:
And the equilibrium expression is:
Which is solved for x as follows:
Which means the pOH is:
And the pH:
Regards!
Answer:
. All redox reactions occur with a simultaneous change in the oxidation numbers of some atoms. At least two elements must change their oxidation numbers. When an oxidation number of an atom is increased in the course of a redox reaction, that atom is being oxidized

Explanation:
The units that acceleration use are distance/time^2 (in metric units).
The acceleration is the change of velocity over time, so
In another way, if the velocity is constant, the acceleration is zero, but if the velocity change over the time (as a car do when the red light change), the acceleration takes value!.
