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
