Results Part A. Activities of Metals Record your observations for each reaction (or non-reaction) in Table 9-2. Indicate which ele- ment is more active and which is less active for each pair. Table 9-2. Test Tube Observations More Active Element Less Active Element 1 Copper darken rapidly Cu Ag 2 Zn 3 No reaction Mg Solution becoming yellow and b Fe Hhhle annoar on the surface No reaction Zn(NO3) HCI 4 Fe 5 Cu(NO3)2 Dark in color Zn Mg dark in color, crystal Of cop Mg 6 Cu(NO3)2 ner metal 7 No reaction H2SO4 Cu
Questions 1. Complete and balance the equations for each of the seven experiments you conduct- ed in Part A. Cu + AgNO3 → Cu(NO3)2 +2Ag a. b. Zn + Mg(NO3)2 → No reaction c. Fe + HCI ► FeCl2 +H2 d. Fe + Zn(NO3)2 No reaction e. Zn + Cu(NO3)2 → Cu+ Zn(NO3)2 f. Mg + Cu(NO3)2 + 2 MgNO3 +Cu g. Cu + H2SO4 → No reaction 2. In the blanks below, list the six elements you tested in Part A in order from least active to most active. Ag (least) Cu H Fe Zn Mg (most) LAB 9 Single Displacement Reactions LAB LAB 9 Single Displacement Reactions 9 65 Name Date WORKSHEET (cont.) 3. In Part A, only five experiments were needed to correctly arrange the six elements in activity order. Which two experiments could have been eliminated? Were the results of the addition- al experiments consistent with the other results? Explain.
