Mixture vs Compound

Definition
A mixture is a combination of two or more substances that are not chemically bonded together. On the other hand, a compound is a substance composed of two or more elements chemically combined in a fixed ratio.

Composition
- Mixture: Each substance in a mixture retains its own properties and can be separated physically.
- Compound: Compounds have a definite composition and properties different from the elements that form them. They can only be separated through chemical reactions.

Physical Properties
- Mixture: The physical properties of a mixture are a blend of the properties of its individual components.
- Compound: Compounds have unique physical properties distinct from the elements they are composed of.

Separation
- Mixture: Mixtures can be separated through physical methods like filtration, distillation, or evaporation.
- Compound: Compounds can only be separated into their constituent elements through chemical reactions.

Examples
- Mixture: Saltwater, air, trail mix.
- Compound: Water (H2O), carbon dioxide (CO2), sodium chloride (NaCl).

Conclusion
In summary, mixtures are combinations of substances that retain their individual properties and can be physically separated, while compounds are chemically bonded substances with unique properties that can only be separated through chemical reactions. Understanding the differences between mixtures and compounds is essential in the field of chemistry.
