Base your answers to questions 62 through 65 on the information below
and on your knowledge of chemistry.
An operating voltaic cell has zinc and iron electrodes. The cell and the
unbalanced ionic equation representing the reaction that occurs in the
cell are shown below.
62 Identify the subatomic particles that flow through the wire as the
cell operates. [I]
63 Balance the equation in your answer booklet for the
redox reaction that occurs in this cell, using the smallest whole-number
|Answer--> __3__Zn(s) +
64 Identify one metal from table J that is more easily
oxidized than Zn.
|Answer-->a metal above Zn....Mn,Ti, Al, Mg, Na, Ca, Sr, Ba,
Cs, K, Rb, Li
65 Explain, in terms of Zn atoms and Zn ions, why the
mass of the Zn electrode decreases as the cell operates.
|Answer--> the Zn atoms become Zn2+
