Copper metal, $Cu\text{Cu}$ , can be extracted by heating copper oxide, $CuO\text{CuO}$ , with carbon, $C\text{C}$ .

2\text{CuO} + \text{C} \rightarrow 2\text{Cu} + \text{CO}_2

What is the percentage atom economy for the production of copper?

( $M_r$ : $CuO=80\text{CuO} = 80$ , $C=12\text{C} = 12$ , $Cu=64\text{Cu} = 64$ , $CO2=44\text{CO}_2 = 44$ )

$37%37\%$

$58%58\%$

$74%74\%$

$100%100\%$
