The balanced equation for the reaction of aqueous Pb(ClO3)2 with aqueous NaI is as below
Pb(ClO3)2(aq) + 2NaI(aq) → PbI2(s) + 2 NaClO3(aq)
Explanation
from the equation above 1mole of lead(ii) chlorate Pb(ClO3)2 react with 2 moles of sodium iodide to form 1 moles of lead(ii) iodide( PbI2) and 2 moles of sodium chlorate NaClO3.
