What is the type of the first reaction? Which element is oxidized? Which element is reduced? a double displacement; copper; oxygen not redox; none; none redox; copper; nitrogen a single displacement; nitrogen; copper A copper cycle experiment takes copper atoms through reactions that produce copper compounds and complexes one after the other, finally producing elemental copper. Copper atoms are conserved throughout the process. Given that a student begins with 9.81 mL of a 0.29 M Cu(NO3)2 solution, how much copper should be isolated at the end of the cycle? theoretical yield of copper = g 50
