I need help finishing this equation.

Fes + Cu2S + O2 -->

Fes?

are you speaking of FeS?

 

if so, it depends on the temperature you have; the sulfur should oxidize, but it could oxidize to one of many states

bud, can you guide me to a page where it's explained the basics of what happens in reactions? Like "Ok, that has a and b so they form a compound if temp. over 500 C". I have some basic info about it (like thermite reactions and such), but not too much. :|

well...im not sure of a certain specific page, but think of it this way;

oxygen is a strong oxidizing agent, with the second highest electronegativity of all of the elements. sulfur easily oxidizes to the dioxide, but also forms sulfites, sulfates, persulfates, thiosulfates and the like. copper and iron would only be cationic in these. so, im thinking they could form something like:

[math]FeS + Cu_2S + 4O2 --> FeCu_2(SO_4)_2[/math]

or it could form [math]FeCu_2(SO_3)_2[/math]
