Stoichiometry & Chemical ReactionsComproportionation Reaction
A redox reaction in which two species of the same element in different oxidation states combine to give a single intermediate state.
Stoichiometry & Chemical ReactionsCondensation Reaction
A reaction in which two molecules join with the elimination of a small molecule, usually water.
Stoichiometry & Chemical ReactionsDecomposition Reaction
A reaction in which a single compound breaks down into two or more simpler substances.
Stoichiometry & Chemical ReactionsDehydration Reaction
A reaction in which water is removed from a single molecule, generally producing an unsaturated or condensed product.
Stoichiometry & Chemical ReactionsDisproportionation Reaction
A redox reaction in which a single species is simultaneously oxidised and reduced.
Stoichiometry & Chemical ReactionsDouble Displacement Reaction
A reaction in which two compounds exchange partner ions to form two new compounds.
Stoichiometry & Chemical ReactionsEffervescence
The rapid escape of gas bubbles from a liquid during a chemical reaction.
Stoichiometry & Chemical ReactionsElimination Reaction
A reaction in which two substituents are removed from adjacent atoms, generating a multiple bond.
Stoichiometry & Chemical ReactionsEndothermic Reaction
A reaction that absorbs energy from the surroundings, giving a positive enthalpy change.
Stoichiometry & Chemical ReactionsEquivalent Weight
