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.
