8. One of the reactions used in the smelting of copper ores to produce copper involves reacting copper (1) oxide with copper (II) sulfide. The balanced equation for the reaction is given below: Cu o (s) + Cus (s) Cu (s) + SO2 (g) 250.0 g of copper (1) oxide is reacted with 129.0 g of copper (11) sulfide. What is the maximum mass of copper that can be purified? If 225.0 g of copper is actually recovered, determine the percent yield. (6 MARKS) 8.
