Study Notes
Chemistry
- Study of matter and its properties, changes, and interactions.
Matter
- Defined as anything that possesses volume and occupies space.
Pure Substances
- Consists of a single type of particle, creating a uniform composition.
Elements
- Fundamental substances that cannot be chemically broken down into simpler materials.
Compounds
- Chemical combinations of two or more elements in a fixed ratio, having distinct properties.
Mixtures
- Combinations of two or more pure substances, retaining their individual properties.
Homogeneous Mixture
- Consists of a single visible phase, appearing uniform throughout.
Heterogeneous Mixture
- Contains two or more visible phases or components that can be distinguished.
Colloids
- A type of mixture where particles remain suspended and do not settle, exhibiting the Tyndall effect.
Tyndall Effect
- Phenomenon where light is scattered by particles in a colloid, making it appear luminous.
Suspensions
- Mixtures where larger particles eventually settle out, separating from the liquid.
Mechanical Mixtures
- Mixtures where the distinct parts can be visually identified and separated.
