- Copper oxide reacts with hydrogen to produce copper. The equation for the reaction is: CuO+H_(2)arrow Cu+H_(2)O Calculate the percentage atom economy for obtaining copper from this reaction. Use the equation: Percentage atom economy=(A_(r) of Cu)/(M_(r) of H_(2)+M_(r) of CuO)times 100 Relative atomic mass (A_(r)) Cu=63.5 Relative formula masses (M_(t)) H2=2 H_(2)=2 CuO=79.5 [2 mar
