Of the above options you've given, the only nuclear reaction is fission.
fermentation is when organic matericals go bad and delope mold for exg,
reduction is when atoms of elements have their oxidation states changed (exg rusting)
deposition is when molecules set out in any sort of solution.
Hello!
To solve this problem we need to know the value of
pKa for HC₂H₃O₂ (Acetic Acid) which is
4,76. Now we can apply the
Henderson-Hasselbach equation, as follows (assuming that HC₂H₃O₂ concentration is 0,22M):
![pH=pKa + log ( \frac{KC_2H_3O_2}{HC_2H_3O_2} )=4,76 + log ( \frac{0,122M}{0,22M} )=4,50](https://tex.z-dn.net/?f=pH%3DpKa%20%2B%20log%20%28%20%5Cfrac%7BKC_2H_3O_2%7D%7BHC_2H_3O_2%7D%20%29%3D4%2C76%20%2B%20log%20%28%20%5Cfrac%7B0%2C122M%7D%7B0%2C22M%7D%20%29%3D4%2C50)
So, the pH for this buffer solution of HC₂H₃O₂ and KC₂H₃O₂ is
4,50Have a nice day!

What is a mole?</h3>
A mole is defined as 6.02214076 ×
of some chemical unit, be it atoms, molecules, ions, or others.
Calculating moles of ![CO_2](https://tex.z-dn.net/?f=CO_2)
Number of mole of
= ![\frac{\;Given \;mass}{\;Molar \;mass}](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%3BGiven%20%5C%3Bmass%7D%7B%5C%3BMolar%20%5C%3Bmass%7D)
=
= 0.12 mol
As is clear from the reaction stoichiometry, 9 moles of
