Question #38980

Answer 1

`"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.
