Results for “Mole”
17 terms
Lattice Energy
The energy released when one mole of an ionic solid is formed from its constituent gaseous ions.
Chemical Bonding & Molecular StructureLewis Structure
A diagram showing the bonding and lone pairs of a molecule using dots or lines for valence electrons.
Inorganic & Coordination ChemistryLigand
An ion or molecule that donates one or more electron pairs to a central metal atom.
Inorganic & Coordination ChemistryLigand Field Theory
The refined bonding model that combines crystal field theory with molecular orbital treatment of metal–ligand covalency.
Chemical Bonding & Molecular StructureLinear Geometry
A molecular shape in which the bonded atoms lie on a straight line, giving a bond angle of 180°.
Biochemistry & Polymer ChemistryLipid
A biomolecule that is largely non-polar and therefore insoluble in water but soluble in organic solvents.
States of Matter & Gas LawsLiquid Crystal
A state of matter that flows like a liquid but retains some of the molecular ordering of a crystal.
Chemical Bonding & Molecular StructureLondon Dispersion Forces
Attractions between molecules caused by instantaneous fluctuations in electron distribution inducing dipoles in neighbours.
Chemical Kinetics & CatalysisLangmuir Adsorption Isotherm
A model describing monolayer adsorption on a surface with a fixed number of equivalent, independent sites.
States of Matter & Gas LawsLatent Heat
The energy absorbed or released when a substance changes state, with no accompanying change in temperature.
Foundations of ChemistryLaw of Definite Proportions
The principle that a given chemical compound always contains its constituent elements in the same fixed mass ratio.
Solutions & Colligative PropertiesLike Dissolves Like
The empirical rule that substances dissolve best in solvents with similar polarity and bonding character.
Stoichiometry & Chemical ReactionsLimiting Reagent
The reactant that is completely consumed first and therefore determines the maximum amount of product obtainable.
States of Matter & Gas LawsLiquid State
The state of matter with a definite volume but no fixed shape, in which particles are close together yet free to move past one another.
Chemical Bonding & Molecular StructureLone Pair
A pair of valence electrons localised on one atom and not involved in bonding.
Chemical EquilibriumLe Chatelier's Principle
When a system at equilibrium is disturbed, it responds in the direction that partially opposes the disturbance.
Acids, Bases & SaltsLewis Theory
The theory defining an acid as an electron pair acceptor and a base as an electron pair donor.
