When potassium iodide solution is added to a solution of lead nitrate in a testtube, a precipitate is formed.
Write the balanced chemical equation for this reaction.

Explanation

To write the balanced chemical equation for the reaction between potassium iodide (KI) and lead nitrate (Pb(NO3)2), follow these steps:

### Step 1: Identify the Reactants and Products
- The reactants are potassium iodide (KI) and lead nitrate (Pb(NO3)2).
- The products formed are lead iodide (PbI2), which is a precipitate, and potassium nitrate (KNO3).

### Step 2: Write the Unbalanced Chemical Equation
The unbalanced chemical equation can be written as:
