General chemistry

The change in enthalpy that occurs when one mole of a compound is converted into gaseous atoms. All bonds in the compound are broken in atomization and none are formed, so enthalpies of atomization ...

node

Chemistry; General chemistry

A point, region, or surface where the amplitude of a standing wave is zero. The probability of finding an electron at an orbital node is zero.

thin layer chromatography

Chemistry; General chemistry

A technique for separating components in a mixture on the basis of their differing polarities. A spot of sample is placed on a flat sheet coated with silica and then carried along by a solvent that ...

isothermal

Chemistry; General chemistry

Having constant temperature.

scientific notation

Chemistry; General chemistry

A system for reporting very small or very large numbers by writing the number as a decimal number between 1 and 10, multiplied by a power of 10. For example, 602000000000000000000000 is written in ...

allosteric effect

Chemistry; General chemistry

A change in the behavior of one part of a molecule caused by a change in another part of the molecule.

enthalpy of combustion

Chemistry; General chemistry

The change in enthalpy when one mole of compound is completely combusted. All carbon in the compound is converted to CO2(g), all hydrogen to H2O( ), all sulfur to SO2(g), and all nitrogen to N2(g).
