Defination of Mixture explanation and examples and types of mixture

Definition of Mixture:
A mixture is a physical combination of two or more substances, where each substance retains its chemical properties. Mixtures can be composed of elements, compounds, or other mixtures.
Explanation:
Mixtures are formed when two or more substances are combined, but they don't chemically react with each other. The substances in a mixture can be separated by physical means, such as filtration, distillation, or chromatography.
Examples of Mixtures:
1. Air (a mixture of gases: nitrogen, oxygen, carbon dioxide, etc.)
2. Water and salt (a mixture of two substances: water and sodium chloride)
3. Trail mix (a mixture of nuts, seeds, and dried fruits)
4. Soil (a mixture of minerals, organic matter, and water)
5. Blood (a mixture of plasma, red blood cells, white blood cells, and platelets)
Types of Mixtures:
1. Homogeneous Mixtures (Solutions):
Uniform composition throughout
Examples: sugar solution, saltwater, air
2. Heterogeneous Mixtures:
Non-uniform composition
Examples: sand and water, trail mix, soil
3. Suspensions:
Particles settle over time
Examples: muddy water, flour in water
4. Colloids:
Particles don't settle, but are dispersed throughout
Examples: milk, ink, fog
5. Emulsions:
Mixtures of two or more liquids that don't normally mix
Examples: oil and water, mayonnaise, lotion
Note: These categories can overlap, and some mixtures can exhibit properties of multiple types.
