When elemental copper is strongly heated with sulfur, a mixture of CuS and Cu2S is produced, with CuS predominating.
Cu(s)+ S(s) CuS(s)
2Cu(s) + S(s) → Cu,S(s)
What is the theoretical yield of CuS when 34.20 g of Cu(s) is heated with 45.70 g of S? (Assume only CuS is produced in the reaction.)
Theoretical yield =
What is the percent yield of CuS if only 31.8 g of CuS can be isolated from the mixture?
Percent yield =
