Single Displacement
The reaction of Fe2O3 and H2S produces FeS, sulfur and water. The complete chemical reaction is Fe2O3 + H2S = 2 FeS + S + 3 H2O.
In the reaction FeS + 2HCl --> FeCl2+ H2S, the iron replaces the hydrogen and the hydrogen replaces the iron. This is two replacements, so the reaction is a double replacement reaction. (It's sometimes also called a double displacement reaction.)
Carbon, Sulfur, CO, FeCl2, MnO2..
Balancing equation of FeCl2 and Na2CO3 yield 2NaCl and FeCO3

Iron(III) chloride can react with iron or copper and form iron (II) chloride.
In the reaction FeS + 2HCl --> FeCl2+ H2S, the iron replaces the hydrogen and the hydrogen replaces the iron. This is two replacements, so the reaction is a double replacement reaction. (It's sometimes also called a double displacement reaction.)

Very fast corrosion e.g Fe + 2HCl -----> FeCl2 + H2
how FeCl2 is made
The mass of of iron(II) chloride (anhydrous) is 633,8 grams.
Oxidant half reaction: 2H+ + 2e- --> H2 Reductant half reaction: Fe --> Fe2+ + 2e- Tribune ions: 2Cl- --> 2Cl-
Iron (II) chloride and sodium hydroxide react to produce iron (II) hydroxide and sodium chloride. FeCl2(aq) + NaOH(aq) --> Fe(OH)2(s) + NaCl(aq) This is a double replacement/displacement reaction.
3 mole FeCl2 will react with 6 mole NaOH (stoechiometric mole ratio: 1 FeCl2 to 2 NaOH), so 3 mole FeCl2 (= 6 added -3 used) will be left over.
