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) → Cu₂S(s) What is the theoretical yield of CuS when 33.70 g of Cu(s) is heated with 45.80 g of S? (Assume only CuS is produced in the reaction.) Theoretical yield = What is the percent yield of CuS if only 36.2 g of CuS can be isolated from the mixture? Percent yield =
