Choose an expression for the acid ionization constant (Ka)(Ka) for HFHF. Choose an expression for the acid ionization constant for . Ka=[H3O+][F−][HF]Ka=[H3O+][F−][HF] Ka=[F−][H3O+][HF]Ka=[F−][H3O+][HF] Ka=[HF][H3O+][F−]Ka=[HF][H3O+][F−] Ka=[H3O+][HF][F−]Ka=[H3O+][HF][F−]

Explanation:

Let's consider the acid dissociation of hydrofluoric acid according to Brönsted-Lowry theory.

HF(aq) + H₂O(l) ⇄ F⁻(aq) + H₃O⁺(aq)

The equilibrium constant for this reaction is known as acid ionization constant (Ka). It only includes aqueous species and gases if there were. The acid ionization constant is:

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
