In chemistry, a reaction quotient Qr is a function of the activities or concentrations of the chemical species involved in a chemical reaction.

A chemical oxygen generator is a device that releases oxygen via a chemical reaction.

Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction.

An elementary reaction is a chemical reaction in which one or more of the chemical species react directly to form products in a single reaction step and with a single transition state.

Establishing free energy relationships helps in the understanding of the reaction mechanism for a chemical reaction and allows the prediction of reaction rates and equilibrium constants.

Dehydrogenation is a chemical reaction that involves the removal of hydrogen from a molecule.

A chemical reaction is a transformation of some substances into one or more different substances.

A by product is a secondary product derived from a manufacturing process or chemical reaction.

It is used to provide even heating for another container, most often during a chemical reaction.

In chemistry, a precursor is a compound that participates in the chemical reaction that produces another compound.

It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid base reactions.

The Eyring equation (occasionally also known as Eyring Polanyi equation) is an equation used in chemical kinetics to describe the variance of the rate of a chemical reaction with temperature.

The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed.

)We now relax the requirement of a homogeneous bulk system by letting the chemical potentials and the affinity apply to any locality in which a chemical reaction (or any other process) is occurring.

Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus.

High temperatures are suitable for electricity generation using conventional methods like steam turbine or a direct high temperature chemical reaction such as liquid salt.

It contains some of the earliest modern ideas of atoms, molecules, and chemical reaction, and marks the beginning of the history of modern chemistry.

However, concern that the Syrian government could intensify 160 its use of chemical weapons against rebel held areas, or that rebels could initiate attacks or respond with captured chemical weapons, raises questions about the pattern s durability and the international community s reaction.

LONDON Europe s reaction to the historic revolutions in North Africa has vacillated between exhilaration and fear.

The general reaction of photosynthetic photolysis can be given asH2A 2 photons (light) 2 e 2 H AThe chemical nature of A depends on the type of organism.

Bond order is the number of chemical bonds between a pair of atoms.

There is always a process involved in changing the composition e.g., a chemical reaction (or many), or movement of molecules from one phase (liquid) to another (gas or solid).

The Kolbe Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by heating sodium phenolate (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 C), then treating the product with sulfuric acid.

Chain termination is any chemical reaction that ceases the formation of reactive intermediates in a chain propagation step in the course of a polymerization, effectively bringing it to a halt.

America s public reaction has been as remarkable as the Lancet study, for the reaction has been no reaction.

The reaction can be represented with the chemical equation 2 As 3 S As2S3Upon heating in a vacuum, polymeric As2S3 cracks to give a mixture of molecular species, including molecular As4S6.

By using a chemical reaction rather than a connection to an oxygen tank, these devices supply breathing oxygen for long enough for the airliner to descend to thicker, more breathable air.

The Betti reaction is a special case of the Mannich reaction.

This reaction can also be considered a reaction between a base and a Lewis acid with the copper atom in the electron receiving role and the pi electrons of the gas molecule in the electron donating role.

When the gas created by the chemical reaction is released, it should rise into the eudiometer so that the experimenter may accurately read the volume of the gas produced at any given time.
