* Skeleton Equation: A skeleton equation simply lists the chemical formulas of the reactants and products, without balancing the number of atoms on each side. It's like a basic outline of the reaction.

* Balanced Chemical Equation: A balanced chemical equation shows the same number of atoms of each element on both the reactant and product sides. This follows the law of conservation of mass, ensuring that no atoms are created or destroyed during the reaction.

Here's an example:

Skeleton Equation:

Fe + O₂ → Fe₂O₃

Balanced Chemical Equation:

4Fe + 3O₂ → 2Fe₂O₃

Key Difference: The balanced equation has coefficients (4, 3, and 2) in front of the chemical formulas, ensuring that the number of iron (Fe) and oxygen (O) atoms is the same on both sides.
