Explanation / Answer

Q1.

sodium acetate + acetic acid

C2H3O2- + HC2H3O2 <--> HC2H3O2 + C2H3O2-

this is dinamic equilbirium, that is, there is reverse/forward reactions

and this is simply 1 molecules of acetate accepting 1 mol of H+ per mol of acid.

In reallity, we will assume no overall reaction

Q2

NH3 + HCl = NH4Cl

ionic

NH3 + H+ + Cl- = NH4+ + Cl-

net ionic includes only reacting ions

NH3 + H+ = NH4+

Q#

acetic acid + HCl

CH3COOH + HCl --> CH3COOH + H+ + Cl-

note that there is no reaction

in reallity, what this is happening

CH3COO- + H+ --> CH3COOH

which implies that the few CH3COO- present in solution will be forming CH3COOH
