Study Notes
Pure Substances and Mixtures
- Homogeneous Mixtures: Solutions that appear uniform throughout, where individual components are not distinguishable.
- Heterogeneous Mixtures: Mixtures with visibly different components and uneven distribution.
Examples of Homogeneous Mixtures
- Chocolate Milk: A mixture that is well-blended and appears uniform.
- Sugar Water: A solution where sugar is completely dissolved in water, resulting in a clear liquid.
- Air: A homogeneous mixture containing nitrogen, oxygen, and trace gases, evenly distributed.
Examples of Heterogeneous Mixtures
- Damp Soil: Contains distinct particles and organic matter that can be seen and identified.
- Taco Soup: A mixture with separate ingredients like beans, meat, and vegetables that remain identifiable.
- Stir Fry: A collection of different vegetables and proteins that retain their individual characteristics and textures.
Key Definitions
- Matter: Any substance that possesses mass and occupies space, forming the basis of everything in the physical world.
- Pure Substance: A type of matter with a fixed composition and defined properties, either as an element or a compound.
- Mixture: A physical combination of two or more substances that are not chemically bonded, allowing for varied compositions.
Elements and Compounds
- Element: A basic substance consisting of only one type of atom, which cannot be broken down into simpler substances. Example: Aluminum.
- Compound: A substance formed from two or more different elements chemically combined in fixed ratios, represented by a chemical formula. Example: Sodium Chloride (NaCl).
Additional Examples
- Salt Water: A common example of a mixture where salt is mixed with water, maintaining the properties of both components.
