Chemical Compounds

A chemical compound 🧪 is a substance made when two or more different elements 🔬 are chemically bonded together in fixed amounts. These compounds have unique properties ✨ that are different from the original elements, and they can only be separated by chemical reactions ⚗️. Examples include water 💧 (H₂O), carbon dioxide 🌫️ (CO₂), and salt 🧂 (NaCl).
