Study Notes
Organic Compounds
- Derived from living organisms
- Examples: Carbohydrates, proteins, fats
- Can combine without chemical processes, like milk powder and water
Inorganic Compounds
- Created in laboratories
- Classified into: Acids, Bases, Salts, Oxides, Alkalides
Mixture Classification
- One-phase system, uniformly distributed particles, invisible: Homogeneous mixture (e.g., sugar dissolved in water)
- Multiple phases, visible particles, identifiable components: Heterogeneous mixture (e.g., sand and water)
Separation of Mixtures
- Filtration: Separates a solid from a liquid
- Distillation: Separates liquids based on boiling points
- Evaporation: Separates a solid dissolved in a liquid by heating it
- Chromatography: Separates substances based on their different affinities for a stationary and mobile phase
Properties of Matter
- Physical properties: Observable and measurable without altering the substance's composition (e.g., color, density, melting point)
- Chemical properties: Describe a substance's ability to change into new substances (e.g., flammability, corrosion)
Compounds
- Classification: Based on the elements they contain (e.g., water (Hâ‚‚O) is a compound of hydrogen and oxygen)
