Law of Combining Volumes (Gay-Lussac's Law)

At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.

 

Denaturation

A process pertaining to a change in structure of a protein form regular to irregular arrangement of the polypeptide chains.

Foam

Colloidal suspension of a gas in a liquid.

Mass Action Expression

For a reversible reaction, aA + bB cC + dD the product of the concentrations of the products (species on the right), each raised to the power that corresponds to its coefficient in the balanced chemical equation, divided by the product of the concentrations of reactants (species on the left), each raised to the power that corresponds to its coefficient in the balanced chemical equation. At equilibrium the mass action expression is equal to K, at other times it is Q.[C]c[D]d [A]a[B]b = Q, or at equilibrium K.

D-Orbitals

Beginning in the third energy level, aset of five degenerate orbitals per energy level, higher in energy than s and p orbitals of the same energy level.

 

Concentration

Amount of solute per unit volume or mass of solvent or of solution.

Combustible

Classification of liquid substances that will burn on the basis of flash points. A combustible liquid means any liquid having a flash point at or above 37.8°C (100°F) but below 93.3°C (200°F), except any mixture having components with flash points of 93.3°C (200°F) or higher, the total of which makes up 99 percent or more of the total volume of the mixture.

Hydrometer

A device used to measure the densities of liquids and solutions.

Disproportionation Reactions

Redox reactions in which the oxidizing agent and the reducing agent are the same species.

Electrolysis

Process that occurs in electrolytic cells.

Calorimeter

A device used to measure the heat transfer between system and surroundings.

Surface Tension

It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.

Ketone

Compound in which a carbonyl group is bound to two alkyl or two aryl groups, or to one alkyl and one aryl group.

Oil

Liquid triester of glycerol and unsaturated fatty acids.

Safranine

Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.

Heat

A form of energy that flows between two samples of matter because of their differences in temperature.

Homogeneous Catalyst

A catalyst that exists in the same phase (solid, liquid or gas) as the reactants. The process is called Homogeneous Catalysis.

Electron Configuration

Specific distribution of electrons in atomic orbitals of atoms or ions.

Dissociation

In aqueous solution, the process in which a solid ionic compound separates into its ions.

Critical Mass

The minimum mass of a particular fissionable nuclide in a given volume required to sustain a nuclear chain reaction.
