Question
Explain how to balance a chemical equation by giving an example.
✓
Answer
This means there must be the same mass of atoms on both sides of a chemical equation, and therefore the same number of atoms. For example, consider the simple chemical reaction Ca + Cl2 $\rightarrow$ CaCl2. This equation is already balanced because it has the same number of Ca and Cl atoms on each side.
