What is the sum coefficient and balanced equation of:

Question

Fe(CN)3+H2S--->

Answer 1

Based on my knowledge in inorganic chemistry in my dissertation, I can state the equation of this reaction.

2 Fe(CN)3 + H2S => 2 Fe(CN)2 + 2 HCN + S

But this reaction is complex and heterogen in detail. Its a heterogene reaction, because Fe(CN)3 is solid or colloide, the reaction products are solid or colloide.
