🔬 Separation Methods for Compounds (Chemical Changes Required)

Electrolysis

• Used to break down compounds using electricity.

• Example: Splitting water (H₂O) into hydrogen and oxygen gases.

• 💡 Commonly taught in chemistry to show how chemical bonds can be broken.

Thermal Decomposition

• Using heat to break a compound into simpler substances.

• Example: Heating calcium carbonate (CaCO₃) → calcium oxide (CaO) + carbon dioxide (CO₂).

• 🔥 Requires high temperatures.

Chemical Reactions

• Reacting a compound with another substance to break it apart or form new compounds.

• Example: Reacting acids with carbonates or metals.

• 🧪 Often used in labs to isolate elements or simpler compounds.
