Answer:

#"CoSO"_4+"Pb(NO"_3)_2->"Co(NO"_3)_2+"PbSO"_4#

Explanation:

Reactants:
1. Cobalt (II) #=># An ion of Cobalt, Co
having valency of #2+ =>"Co"^(2+)# and Sulfate #=>"SO"_4^(2-)# ion
Combining both the chemical formula of first reactant is #"CoSO"_4#
2. Similarly Lead (II) #=>"Pb"^(2+)#
and Nitrate #=>"NO"_3^-# ion
Observe that each ion of Lead will require two ions of nitrate to satisfy (quench) its valency. Therefore, combining both we obtain chemical formula of second reactant as #"Pb(NO"_3)_2#

Products:
Following the same logic as used for reactants
1. Cobalt (II) Nitrate has chemical formula as #"Co(NO"_3)_2#
and
2. Lead (II) Sulfate has chemical formula as #"PbSO"_4#

Writing the chemical equation of the reaction
Reactants #-># Products

#"CoSO"_4+"Pb(NO"_3)_2->"Co(NO"_3)_2+"PbSO"_4#
Inspection reveals that the equation is already balanced.
