Properties of Substances and Mixtures

These flashcards cover key vocabulary related to the properties of substances and mixtures, as discussed in the lecture notes.

Properties of Solids

Many properties of solids are determined by the strength of intermolecular forces (IMFs) present.

Distillation

A separation technique based on differences in boiling points of substances.

Covalent Network Solids

Solids held together by covalent bonds in a large network, e.g., diamond and graphite.

Ionic Solids

Solids made up of oppositely charged ions held together by ionic bonds.

Metallic Solids

Solids in which metal atoms are held together by metallic bonds.

Polymers

Large, chain-like molecules with high molecular weight formed through covalent bonds.

Molecular Solids

Solids made of molecules or atoms held together by IMFs, typically softer with lower melting points.

Hydrogen Bonding

A strong type of dipole-dipole attraction that occurs between molecules with hydrogen attached to electronegative atoms.

Electrostatic Attractions

Forces that hold ionic solids together, described by Coulomb's Law.

Molar Mass

The mass of one mole of a substance, expressed in grams per mole.
