The number of atoms of a molecule or compound is balanced on either side of a chemical equation by keeping appropriate _________ .

Explanation

To answer the question, "The number of atoms of a molecule or compound is balanced on either side of a chemical equation by keeping appropriate _________," we need to understand the concept of balancing chemical equations.

### Step-by-Step Solution:

1. **Understanding Chemical Equations**: A chemical equation represents a chemical reaction where reactants are transformed into products. The left side of the equation shows the reactants, and the right side shows the products.

2. **Balancing Atoms**: In a balanced chemical equation, the number of atoms of each element must be the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
