2. a. no reaction
b. no reaction
c. Fe (s) + 3AgNO3 (aq) = 3Ag + (s) + Fe(NO3)3 (aq)
NIE: 3 Ag +1 (aq) + Fe(s) = 3Ag (s) + Fe +3 (aq)
d. no reaction
e. Ca(s) + 2AgNO3(aq) = Ca(NO3)2(aq) + 2 Ag(s)
NIE: Ca(s) + 2Ag +1 (aq) = Ca+2 (aq) + 2Ag(s)

3. This shows that the material used to make quarters was lower in the series because that
