Why is it always essential to balance a chemical equation?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Law of Conservation of Mass:**
- The law states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products. This means that matter is neither created nor destroyed during a chemical reaction.

2. **Importance of Balancing Chemical Equations:**
- Balancing a chemical equation ensures that the number of atoms for each element is the same on both sides of the equation. This is crucial because it reflects the conservation of mass.
