Copper can be extracted by heating copper(II) oxide with carbon.
The balanced chemical equation for the reaction is:
2CuO+C→2Cu+CO2 2\text{CuO} + \text{C} \rightarrow 2\text{Cu} + \text{CO}_2 2CuO+C→2Cu+CO2Calculate the percentage atom economy for the production of copper in this reaction.
Relative atomic masses (ArA_rAr): C=12\text{C} = 12C=12 O=16\text{O} = 16O=16 Cu=63.5\text{Cu} = 63.5Cu=63.5
Relative formula masses (MrM_rMr): CuO=79.5\text{CuO} = 79.5CuO=79.5 CO2=44\text{CO}_2 = 44CO2=44
