FeS + 2HBr --> FeBr2 + H2S
Fe2+ + S2- + 2H+ + 2Br- --> Fe2+ + 2Br- + H2S
2H+ + S2- --> H2S

K2CO3 + CuCl2 --> 2KCl + CuCO3
2K+ + CO32- + Cu2+ + 2Cl- --> 2K+ + 2Cl- + CuCO3
Cu2+ + CO32- --> CuCO3

FeS(s) + 2HBr(aq) --> FeBr2(aq) + H2S(g)
S2-(aq) + 2H+(aq) --> H2S(g)

K2CO3(aq) + CuCl2(aq) --> 2KCl(aq) + CuCO3(s)
CO3(2-)(aq) + Cu2+(aq) --> CuCO3(s)
