Question #92665

Answer 1

The original equation is wrongly written in the question.

The balanced equation I think should be:

`Pb(NO_3)_2+2KIrarrPbI_2+2KNO_3`

It's a precipitation reaction producing insoluble lead (II) iodide. The other ions are spectators:

`Pb_((aq))^(2+)+2I_((aq))^(-)rarrPbI_(2(s))`
