Final answer:
The best representation to show the reaction between lead (II) nitrate and potassium iodide is a chemical equation.
Step-by-step explanation:
The best representation to show the reaction between lead (II) nitrate and potassium iodide is a chemical equation.
The balanced chemical equation for the reaction is:
Pb(NO3)2(aq) + 2 KI(aq) → PbI2(s) + 2 KNO3(aq)
In this representation, the reactants (lead (II) nitrate and potassium iodide) are shown on the left side of the equation, and the products (lead (II) iodide and potassium nitrate) are shown on the right side.
