Question

if an of the following reactions occurs spontaneosly write the balanced net ionic equation if not write no reaction (a)pb+zn2+------pb2+zn(b)Fe+H+------Fe2+ +H2 Cu+Ag+------Cu2++Ag(d)Cr+zn2+-----Cr2++Zn​

Answer 1

Answer:

a) No reaction as reduction potential of Zn is more than Ob

b) Fe + 2H^+ --- Fe^+2 + H2

c) Cu + 2Ag^+ --- Cu^+2 + 2Ag

d) No reaction, as Cr^+2 is very unstable

hope this will help you
