Chemical decomposition of silver sulfide?

Question

What is the balanced equation for the decomposition of silver sulfide? I just can't think!

Answer 1

Silver sulfide is extremely stable. It doesn't decompose easily, except maybe at an extremely high temperature, or by electrolysis of the molten compound.



............heat

8Ag2S ----> 16Ag(s) + S8(g)



You can produce silver metal by reacting it with aluminum, for instance:



... ... ... ... ... ... ... .salt soln.

2Al(s) + 3Ag2S(s) --------> Al2S3 + 6Ag(s)

Answer 2

1. should read: CuSO4 + Al ==> Al2(SO4)3 + Cu You have 2 Al on the right side of the arrow and only one on the left. Put a 2 in front of Al . .CuSO4 + 2Al ==> Al2(SO4)3 + Cu You have 3 SO4 on the right and only one on the left. Put a 3 in front of CuSO4 . .3CuSO4 + 2Al ==> Al2(SO4)3 + Cu You have 3 Cu on the left and only one on the right. Put a 3 in front of Cu . .3CuSO4 + 2Al ==> Al2(SO4)3 + 3Cu . .done. 2. Na2S + AgNO3 ==> NaNO3 + Ag2S You have 2 Na on the left and only one on the right. Put a 2 in front of NaNO3 . .Na2S + AgNO3 ==> 2NaNO3 + Ag2S You have 2 Ag on the right and only one on the left. Put a 2 in front of AgNO3. . .Na2S + 2AgNO3 ==> 2NaNO3 + Ag2S . . .done. 3. H2O2 ==> H2O + O2 Sometimes you just have to use "trial and error." Let's put a 2 in front of H2O2 and H2O. . .2H2O2 ==> 2H2O + O2 . . .that did it!

Answer 3

Ag2S --------- 2Ag + S i think..
