Identify the type of reactions taking place in each of the following cases and write the balanced chemical equation for the reactions.
(a) Zinc reacts with silver nitrate to produce zinc nitrate and silver.
(b) Potassium iodide reacts with lead nitrate to produce potassium nitrate and lead iodide.

Explanation

To solve the given question, we will identify the type of reactions and write balanced chemical equations for each case.

### (a) Zinc reacts with silver nitrate to produce zinc nitrate and silver.

**Step 1: Write the unbalanced chemical equation.**
- Zinc (Zn) reacts with silver nitrate (AgNO₃) to produce zinc nitrate (Zn(NO₃)₂) and silver (Ag).
- The unbalanced equation is:
\[
