Study Notes

Macroscopic Properties of Matter

Macroscopic properties are observable using senses (sight, touch, smell).
Examples include strength, electrical and thermal properties, and solubility.
Microscopic properties relate to the structure and behavior of particles that make up matter, and are not directly observable.
Examples are constituent atoms, types of bonding, and intermolecular forces.
The periodic table helps identify elements and their properties.

Mixtures

Mixtures are a combination of substances that can be separated by physical methods.
Mixtures can be homogeneous or heterogeneous.
Components in a mixture are not in a fixed ratio and maintain their individual properties.

Homogeneous Mixtures

Homogeneous mixtures are mixtures with uniform composition, where components are evenly distributed and indistinguishable.
Examples of homogeneous mixtures include air, alcohol, brine, and steel.

Heterogeneous Mixtures

Heterogeneous mixtures have non-uniform composition, meaning components can be distinguished.
Examples include mud, smoke, cool drink and ice cubes, and blood.

Alloys

Alloys are homogeneous mixtures of metals.
Common alloys include brass (copper and zinc), steel (iron and carbon), bronze (copper and tin), and stainless steel (iron, chromium, and nickel).

Chemical Names and Common Names

Chemical formulas represent the composition of compounds.
Common names are used in everyday language.
Examples:
- H₂O (Hydrogen oxide): Water
- NH₃ (Hydrogen nitride): Ammonia
- NaCl (Sodium chloride): Table salt
- CH₃COOH (Ethanoic acid): Acetic acid (in vinegar)
