Chem Question!?

In the reaction Cu(s) + S(s) -> CuS(s) , it is said that this reaction is not homogeneous. Can someone explain why? Is it because the fact that one is metal and one is non-metal?

Answer:
a homogeneous reaction can only occur in a gaseous or solution phase.

Solids won't just become another solid if you shake em up together.

If you put marbles of sulfer and marbles of copper in a jar, you'd still see a physical boundary bewteen the the copper and sulfur solids.

Whereas if they were in the form of a solution then you wouldn't be able to visibly see a boundary between the compunds.
Homogeneous reactions are chemical reactions in which the reactants are in the same phase, while heterogeneous reactions have reactants in two or more phases. Reactions that take places on the surface of a catalyst of a different phase are also heterogeneous

good luck
