Flashcards: Chemistry

An alloy is a mixture of metals or a mixture of a metal and another element.

Allotropy or allotropism (from Greek ἄλλος (allos), meaning "other", and τρόπος (tropos), meaning "manner, form") is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements.

Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth's atmosphere and that of other planets is studied.

A chemical compound (or just compound if used in the context of chemistry) is an entity consisting of two or more atoms, at least two from different elements, which associate via chemical bonds.

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

A chemist (from Greek chēm (ía) alchemy + -ist; replacing chymist from Medieval Latin alchimista) is a scientist trained in the study of chemistry.

Crystallography is the experimental science of determining the arrangement of atoms in the crystalline solids (see crystal structure).

Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places.

Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds.

Petrochemistry is a branch of chemistry that studies the transformation of crude oil (petroleum) and natural gas into useful products or raw materials.

In chemistry, chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.

Magnetochemistry is concerned with the magnetic properties of chemical compounds.

In chemistry, the study of sonochemistry is concerned with understanding the effect of ultrasound in forming acoustic cavitation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution.

Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g., stress-corrosion cracking or enhanced oxidation), tribology, polymer degradation under shear, cavitation-related phenomena (e.g., sonochemistry and sonoluminescence), shock wave chemistry and physics, and even the burgeoning field of molecular machines.

Bittern (pl. bitterns) is a bitter-tasting solution that remains after evaporation of halite (common salt) from brines and/or seawater.

Chemical biology is a scientific discipline spanning the fields of chemistry, biology, and physics.

Electrolysed water (electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.

Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems.

Bioconcentration is the accumulation of a chemical in or on an organism when the source of chemical is solely water.

A marine chemist is an environmental, occupational safety and health professional who is a trained professional who is responsible for ensuring that repair and construction of marine vessels can be made in safety whenever those repairs might result in fire, explosion, or exposure to toxic vapors or chemicals.
