If no evidence of Metal Compound AgNO Cu(NO3 ) Pb(NO3) Mg(NO3)2 H2SO Zn(NO;)2 Unk he above information write and balance an equation for each reaction that took If no reaction occurred, write "NR". Refer to Appendix I for valences and charges a) Zn +AgNO3 c) Cu +AgNO d) Zn +Cu(NO)2 e) Pb + Cu(NO3)2 -Ph 3)2 Zn+ Pb(NO,)

Answer 1

In the case of displacement reaction the metal which is more reactive can displace the metal ion reacting with. Means if a metal ion solution present and we are putting one metal to this solution which is more reactive than the metal ion present in solution could be displaced as metal.

So for the first reaction

1. Zn + 2 Ag(NO3) -----Zn(NO3)2 + 2Ag

g) Cu + Pb(NO3)2 ----> NR Because Pb has more reactivity than copper

h) Zn + Mg(NO3)2 -----> NR Because Mg has more reactivity than Zn

i) Pb + Mg(NO3)2 -----> NR Because Mg has more reactivity than Pb

j) Cu + Mg(NO3)2 -------> NR Because Mg has more reactivity than Cu

k) Zn + H2SO4 ----- ZnSO4 + H2 Zn is more reactive than H

l) Pb + H2SO4 _------> PbSO4 + H2 Pb is more reactive than H

m) Cu + H2SO4 ------> NR Cu is less reactive than H

n) Pb + Zn(NO3)2 ------> NR Zn is more reactive than Pb

o) Cu + Zn(NO3)2 -----> NR Zn is more reactive than cu

answer 3

activity order of Cu, Zn, Pb, Mg, H, is

Mg > Zn>Pb>H>Cu
