Compound:
Definition: A compound is a substance formed when two or more elements chemically bond together in fixed proportions.
Properties: Compounds have unique properties that are different from the properties of the individual elements. For example, water (H₂O) is a compound made of hydrogen and oxygen, and it has different properties than either element alone.
Separation: Compounds can only be separated into their constituent elements through chemical reactions.
Mixture:
Definition: A mixture is a physical combination of two or more substances where each retains its own properties.
Properties: The components in a mixture can be present in any proportion and maintain their individual characteristics. For example, a salad is a mixture of various vegetables, each keeping its flavor and texture.
Separation: Mixtures can be separated into their individual components using physical methods, such as filtration or distillation.
Summary:
Compounds are chemically bonded, while mixtures are physically combined.
Compounds have fixed ratios and unique properties, whereas mixtures have variable compositions and retain the properties of their components.
