Atoms bond by sharing valence electrons.

Write the balanced equation for the reaction of aqueous Pb(ClO3)2 with aqueous NaI.

Answers

 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.  
Pb(ClO_3)_(2(aq))+2NaI_((aq))=PbI_(2(s))+2NaClO_(3(aq))
