A compound is a substance formed when two or more chemical elements are chemically bonded together. This means that a compound has a fixed ratio of the elements involved, and it typically has properties that are different from those of the individual elements.
Some common examples of compounds include:
- Water (H₂O) - made of hydrogen and oxygen.
- Carbon dioxide (CO₂) - made of carbon and oxygen.
- Sodium chloride (NaCl) - made of sodium and chlorine.
- Glucose (C₆H₁₂O₆) - made of carbon, hydrogen, and oxygen.
If you have a specific list of substances in mind, please provide it, and I can help identify which ones are compounds!
