Study Notes

Classification of Matter

Matter: Defined as anything that possesses mass and occupies space. Examples include everyday objects like an apple or a car.
Mixtures (Impure Substances): Composed of two or more pure substances physically blended together, lacking uniform composition. Examples include saltwater and dust in air.
Pure Substances: Consist of a single type of material with a consistent and definite composition, such as elements like carbon and hydrogen.

Types of Mixtures

Homogeneous Mixtures: Also called solutions, where the composition is uniform throughout, making it impossible to distinguish individual components. Air is a common example.
Heterogeneous Mixtures: Characterized by an inconsistent composition, visible differences can be seen among the components, such as in concrete.

Chemical Compositions

Compounds: These are pure substances formed by chemically bonding two or more elements in fixed proportions, like water (H₂O).
Elements: The simplest form of matter, characterized by unique properties. An example is hydrogen, which cannot be broken down into simpler substances.

Special Mixtures

Solutions: A specific type of homogeneous mixture containing only one type of element or compound; gasoline is an example.
Suspensions: A type of heterogeneous mixture where some particles remain dispersed but can settle over time after being mixed.
Alloys: Materials created by combining two or more metals, exemplified by brass.
Colloids: A category of homogeneous mixtures where particles do not settle out, such as shaving cream.
