Draw up molecular and ionic equations of reactions between substances: sodium sulfide and hydrochloric acid potassium carbonate and nitric acid lead hydroxide and hydrochloric acid iron (III) hydroxide and hydrochloric acid

All reactions go to the end:
1) Na2S + 2 HCl = 2 NaCl + H2S
2 Na (+) + S (-2) +2 H (+) + 2 СL (-) = 2 Na (+) +2 СL (-) + H2S
S (-2) + 2 H (+) = H2S

2) K2CO3 + 2HNO3 = 2 KNO3 + H2O + CO2
2 K (+) + CO3 (-2) + 2H (+) +2 NO3 (-) = 2 K (+) + 2 NO3 (-) + H2O + CO2
CO3 (-2) + 2H (+) = H2O + CO2

3) Pb (OH) 2 + 2HCl = PbCl2 + 2 H2O
Pb (OH) 2 + 2H (+) + 2Cl (-) = Pb (+2) + 2 Cl (-) +2 H2O
Pb (OH) 2 + 2H (+) = Pb (+2) +2 H2O

4) Fe (OH) 3 + 3 HCl = FeCl3 +3 H2O
Fe (OH) 3 + 3 H (+) + 3 Cl (-) = Fe (+3) +3 Cl (-) +3 H2O
Fe (OH) 3 + 3 H (+) = Fe (+3) +3 H2O
