Arrange the three metals(Cu, Zn, and Mg) in order of their relative strengths as reducing agents, placing the strongest first.

Arrange the three metallic ions
( Cu(No3)2, Zn(No3)2, and Mg(No3)2 ) in order of their relative strengths as oxidizing agents, placing the strongest first. Write the reduction half-reaction for each ion.

Write net equations for the following:
a. the reaction of copper and zinc
b. the reaction of zinc and magnesium


please help as much as you can!! thanks sooo much!!!

  1. You know we HELP do homework. I will get you started but leave it for you to finish.
    Mg, Zn, Cu are the three metals placed in order of reducing agents. Mg is the strongest; Cu is the weakest of the three.

    The second one wants the ions of Cu^+2, Zn^+2 and Mg^+2 placed in order of their oxidizing agents.

    The last one I don't understand. There is no reaction between the two metals in either a or b.
