Which element(s) is/are not balanced in this equation? <br> Pb(NO3)2 +2 Kcl -&gt; pbCl2 + KNO3
UkoKoshka [18]

Answer:

The correct answer is KNO3

Explanation:

Pb(NO3)2 +2 KCl -> PbCl2 + KNO3

If we look at the left side of the equation we could see that there are 1 lead atom, 2 nitrate atoms ,2 potassium atoms and 2 chlorine atoms

Now when we look at the right side of the equation, we found that there are –  

1 lead atom and  2 chlorine atoms (PbCl2)  , thus lead and chlorine are balanced as they have the same number of atom in LHS and RHS

There is only 1 potassium and 1 nitrate atom on RHS , thus KNO3 is not balanced.  

The balanced equation would be –  

Pb(NO3)2 +2 KCl -> PbCl2 +2 KNO3
