Answer:
The answer to your question is KNO₃ + PbI₂
Step-by-step explanation:
Data
Chemical reaction
KI + Pb(NO₃)₂ ⇒
Process
We know that this is a double displacement reaction because there are two reactants and each reactant has a cation and an anion (a positive atom and a negative atom or a polyatomic molecule).
To know the products just interchange the cations in each molecule considering the oxidation numbers.
K⁺¹I⁻¹ + Pb⁺²(NO₃)₂⁻¹ ⇒ K⁺¹NO₃⁻¹ + Pb⁺² I₂⁻¹
or
KI + Pb(NO₃)₂ ⇒ KNO₃ + PbI₂
