Gay-Lussac's Law of Combining Volumes
The principle that gases react in volume ratios that are simple whole numbers, when measured at the same temperature and pressure.
Stoichiometry & Chemical ReactionsHalf-Reaction Method
A technique for balancing redox equations by splitting them into separate oxidation and reduction half-equations.
Stoichiometry & Chemical ReactionsHydration Reaction
The addition of water across a multiple bond or the incorporation of water into a crystal lattice.
Stoichiometry & Chemical ReactionsHydrolysis
A reaction in which a bond is cleaved by water, with the H and OH fragments adding to the two products.
Stoichiometry & Chemical ReactionsIrreversible Reaction
A reaction that proceeds essentially to completion, with negligible conversion back to reactants.
Stoichiometry & Chemical ReactionsLaw of Reciprocal Proportions
The principle that the mass ratios in which two elements combine with a third are related by a simple ratio to the ratio in which they…
Stoichiometry & Chemical ReactionsLimiting Reagent
The reactant that is completely consumed first and therefore determines the maximum amount of product obtainable.
Stoichiometry & Chemical ReactionsMole Ratio
The proportion between the amounts of any two substances in a reaction, taken directly from the balanced equation's coefficients.
Stoichiometry & Chemical ReactionsMolecular Equation
A chemical equation in which all reactants and products are written as complete, undissociated formulae.
Stoichiometry & Chemical ReactionsNet Ionic Equation
An equation showing only the species that actually change during a reaction, with all spectator ions removed.
Stoichiometry & Chemical ReactionsNeutralisation Reaction
The reaction between an acid and a base to produce a salt and water.
Stoichiometry & Chemical ReactionsOxidation Number Method
A technique for balancing redox equations by equating the total increase and decrease in oxidation numbers.
Stoichiometry & Chemical ReactionsPercentage Purity
The proportion of a sample that consists of the desired compound, expressed as a percentage of the total mass.
Stoichiometry & Chemical ReactionsPercentage Yield
The actual yield expressed as a percentage of the theoretical yield.
Stoichiometry & Chemical ReactionsPhotochemical Reaction
A reaction initiated by the absorption of light, which promotes a molecule to an electronically excited state.
Stoichiometry & Chemical ReactionsPrecipitate
An insoluble solid that separates from a solution as the result of a chemical reaction.
Stoichiometry & Chemical ReactionsPrecipitation Reaction
A reaction in which two solutions combine to form an insoluble solid that separates from the mixture.
Stoichiometry & Chemical ReactionsProduct
A substance formed as a result of a chemical reaction.
Stoichiometry & Chemical ReactionsPyrolysis

Stoichiometry & Chemical ReactionsReactant
A starting substance that is consumed during a chemical reaction.
Stoichiometry & Chemical ReactionsRearrangement Reaction
A reaction in which the atoms of a molecule are reorganised to give a structural isomer.
Stoichiometry & Chemical ReactionsRedox Reaction
A reaction in which electrons are transferred, so that one species is oxidised while another is reduced.
Stoichiometry & Chemical ReactionsReversible Reaction
A reaction that can proceed in both the forward and reverse directions under the same conditions.
Stoichiometry & Chemical ReactionsRoasting
The heating of a sulfide ore strongly in a plentiful supply of air to convert it into the oxide.
