Ionisation in solution is not a chemical reaction. It can be written as one but still it's NOT: only physical change of state ( subscripted between brackets (s) or (aq) )
Na2S(s) --> 2Na+(aq) + S2-(aq)
Both compounds are soluble in water, so they will form a mixture of cations and anions, but there will be no chemical reaction.
Na2S(aq) + 2NaCl(aq) --> 2Na+(aq) + S2-(aq) + 2Cl-(aq) --> no reaction
Synthesis reaction: 2Na + Cl2 --> 2NaCl
Two substances combine to form a more complex substance
double replacement
The reaction Zn + CuCl2 --> Cu + ZnCl2 is a single-replacement reaction.
single replacement
There will be no reaction. It will remain a mixture.
This is a redox reaction.
I think.... Pb(NO3)2 + Na2S -> PbS + 2(NaNO3) If someone knows for sure please kill my answer.

No, Na2S(aq) + 2HCl(aq) ®2NaCl(aq) + H2S(g) is a double displacement reaction.
A single-replacement reaction
1. Add a small quantity of the FeCl3 solution into the Na2S(aq.). 2FeCl3+3Na2S=2FeS↓+6NaCl+S↓ the following is the ionic reaction equation 2Fe3+ + S2- = 2FeS↓+ S↓ 2. Add a small quantity of the Na2S solution into the FeCl3(aq.) 2FeCl3 + Na2S =2FeCl2 + 2NaCl + S↓ the following is the ionic reaction equation 2Fe3+ + S2- = S↓ + 2Fe2+
Ionic bond
The synthesis reaction is.... Cu + Cl2 --> CuCl2
This is a precipitation reaction.
