chem question

Members do not see this ad.

Li+ CuCl2 --> reaction occurs
Zn+NaNO3 --> no reaction

is that because juss basically Li is an active metal and Zn is not?
when one displaces another (single displacement), does it have to be an active metal to displace another?
or any other reason?

nvm
i got it now lol
i dunno why i got confused by this simple question

This reaction is single displacement reaction. In these reactions more active metals replaced by another. If metal is less active no replacement takes place. Here is the table I got from Wikipedia:
Metals Metal Ion Reactivity Li Li+ reacts with water K K+ Ba Ba2+ Sr Sr2+ Ca Ca2+ Na Na+ Mg Mg2+ reacts with acids H H+ Al Al3+ Mn Mn2+ Zn Zn2+ Cr Cr2+ Fe Fe2+ Cd Cd2+ Co Co2+ Ni Ni2+ Sn Sn2+ Pb Pb2+ H2 H+ included for comparison Sb Sb3+ highly unreactive Bi Bi3+ Cu Cu2+ Hg Hg2+ Ag Ag+ Pt Pt+ Au Au3+
