General chemistry
First order reaction
Chemistry; General chemistry
The sum of concentration exponents in the rate law for a first order reaction is one. Many radioactive decays are first order reactions.
Paraffin
Chemistry; General chemistry
1. a waxy substance that is a mixture of alkanes with chains containing 18 to 36 carbon atoms. 2. An alkane.
Valence shell electron pair repulsion theory
Chemistry; General chemistry
A model that explains the shapes of molecules by assuming that electron pairs arrange themselves around atoms in a way that minimises electron-electron repulsions.
Component
Chemistry; General chemistry
1. A substance whose concentration must be specified to describe the state of a mixture in which reactions are occurring. 2. A substance present in a mixture in which no reactions occur.
Isoelectronic
Chemistry; General chemistry
Refers to a group of atoms or ions having the same number of electrons. For example, F-, Ne, and Na+ are isoelectronic.
Salifiable
Chemistry; General chemistry
Capable of reacting with an acid to form a salt. Lavoisier classified lime, baryta, alumina, and silica as "salifiable earths".
