Mixtures:
* No chemical bonding: The components in a mixture are not chemically bonded together. They are simply physically combined.
* Variable proportions: The components in a mixture can be present in any proportion. You can have more of one ingredient and less of another.
* Retain individual properties: Each component in a mixture retains its original chemical properties. For example, in a mixture of salt and pepper, you can still identify the salt and pepper particles.
Compounds:
* Chemical bonding: The components in a compound are chemically bonded together, forming a new substance with different properties.
* Fixed proportions: The elements in a compound are always present in a fixed, definite ratio. For example, water (H₂O) always has two hydrogen atoms for every one oxygen atom.
* New properties: A compound has properties that are distinct from the elements that make it up. Water is a liquid, while hydrogen and oxygen are gases.
Examples:
* Mixture: Sand and sugar – You can add more sand or more sugar, and the proportions can change.
* Compound: Water (H₂O) – The ratio of hydrogen to oxygen atoms will always be 2:1, no matter how much water you have.
In summary: Mixtures are simply physical combinations of substances, while compounds are formed through chemical reactions that create a new substance with fixed proportions and unique properties.
