The following two reactions are possible methods for refining copper in the final step of a smelting process, i. e., getting pure copper (cu) from copper ores found in rocks. calculate the theoretical atom economy for each reaction. a. 2 cuo(s) + c(s) → 2 cu(s) + co2(g) = % b. cuo(s) + co(g) → cu(s) + co2(g) = %
