Homework Answers
Reactivity of metal decreases from top to bottom in the
series
more reactive metals can displace less reactive metals from its
salt solution
Hence
1) Co + Cu2+ --> Co2+ + Cu . This reaction will take
place
since Co is more reactive
2) Zn + Mg2+ --> Zn2+ + Mg . This reaction will not take
place since Zn is less
reactive than Mg
3) Ni + 2Ag+ --> Ni2+ + 2Ag . This reaction will take place
4) Mn(s) + Ca2+ --> Mn2+ + Ca . This reaction will not take
place
as Mn is less reactive than Ca
Answer
only reactions I and III
