* Elements are pure substances that cannot be broken down into simpler substances by chemical means (like oxygen, carbon, or gold).

* Compounds are formed when two or more elements combine chemically in a fixed ratio (like water, H₂O).

Coca-Cola is made up of many different substances, including:

* Water (H₂O)

* Sugar (primarily sucrose, C₁₂H₂₂O₁₁)

* Carbon dioxide (CO₂)

* Phosphoric acid (H₃PO₄)

* Caffeine (C₈H₁₀N₄O₂)

* Flavorings (including caramel color, natural flavors, and citric acid)

These substances are not chemically bonded together, and their proportions can vary. Therefore, Coca-Cola fits the definition of a mixture.
