PbCl2 + Cl2 = PbCl4
LHS = PbCl2 + Cl2
Pb = valency 4 ( plumbic ) and Cl = valency 2 ( not 1 since it is a molecule)
Pb Cl
4. 2 on cross multiplying we get
PbCl2
when Cl2 and Cl2 combine it gives us Cl4
hence PbCl4
( if you write the eq and the notes in brackets then the answer will be correct as these are the required reasons)
