FeS+HC1--->FeC1(2)+H(2)S. what is the balanced equation thanks.

Wouldnt you need a coefficent of two in front of HCl?

the balanced equation would result like this:

FeS+2HCl-->FeCl2+H2S

therefore, each side is equal
Fe- 1
S- 1
H- 2
Cl-2

    Could you please check my work about complete ionic and net ionic equations. They really confuse me. My original equation, after I balanced, was: FeCl2(aq)+Na2S(aq)=FeS(s)+2NaCl(aq). For complete Ionic I think its: Fe^2+^(aq)+2Cl^-^(aq)+2Na^+^(aq)+S^2-^=FeS(s)+2Na^+^(aq)+2Cl^-^(aq). …
