Copper is obtained from sulfide ores through a two-step process consisting of roasting the ore in the presence of oxygen and heating the resultant copper(1) oxide with powdered carbon. The overall reaction is as follows: 2Cu,S (s) + 302 (g) + 2C (s) → 2SO:(g) + 4Cu (s) + 2CO (g) Calculate the maximum yield of copper obtained from 1.60 kg of Cu2S. (Relative atomic mass: S, 32; O, 16; C, 12; Cu, 64) A. 0.26 kg B. 0.64 kg C. 0.96 kg D. 1.28 kg
