metal Connected connected to potential to a red clip a black clip differe- nce (mv)Cu Mg 1031Mg Cu -1082Cu Sn 329Sn Cu -261Mg Sn -845Sn Mg 7651. From the voltage data construct a partual activity series for the metals: Mg, Sn, and Cn From highest activity series(most likely to be oxidized) to lowest metal on actigity series ( least likely to be oxidized) Note The voltmeter is wired sych that a pistive reading indicates the half- cell connected to the red clip is a site of reducation. 2.)Consider three hypothetical metals: “X”, “Y” and “Z”.The following reactions proceed spontaneously in the direction as written under standard state conditions:X(s) + Z2+ → X2+ + Z(s)Z(s) + Y2+ → Z2+ + Y(s)Complete each of the following statements.If the metal Y is placed into a solution containing 1 M X2+ , a reaction will/will not occur (choose option)Assume the metal Z will dissolve in 1 M HCl. This means the metal X will/ will not ( choose option) dissolve in 1 M HCl.3.) Using a voltameter with alligator clips ( one black and one red). If the voltameter gives a negative voltage reading, which of the following is true? A) the half- cell connected to the black clip is a site of oxidation B) the half- cell connected to the black clip is the site of reduction
