Unformatted text preview: C. Suppose you inserted a piece of an unknown metal into a solution of zinc (II) nitrate and observed no reaction. Then if you inserted the unknown piece of the metal into the solution of iron (III) chloride a deposit formed on the bottom of the well in the well plate. Where does the unknown metal fit into your activity series? D. The chemical reactions for the preceding question number 2 are: Cu (s) + NiCl 2 (aq) à no reaction Fe (s) + NiCl 2 (aq) à 2 Ni (s) + Fe Cl 2 (aq) E. For the second reaction above identify: 1) the oxidation number of Ni (s) = 2) the oxidation number of Fe in the FeCl 2 (aq) = 3) the oxidation number of Cl in the FeCl 2 (aq) = 4) the oxidation number of Fe (s) = 5) the oxidation number of Ni in the NiCl 2 (aq) = 6) the oxidation number of Cl in the NiCl 2 (aq) = 7) the element that is reduced = the element that is oxidized = 8) the reducing agent = the oxidizing agent =...
