27.19 T


termolecular reaction
Require the collision of three particles simultaneously.

tertiary structure
Refers to the overall three-dimensional shape of the entire protein. Determined by the sequence of amino
acids in the protein chain.

tetrahedral
The four bonds take on a tetrahedral shape, again with each electron pair as far away as possible from other
electron pairs.

theoretical yield
The amount of substance that is calculated to be produced.

thermochemistry
The study of energy relationships in chemical reactions.

titrant
Reagent in a titration experiment.

titration
An experiment where a volume of a solution of known concentration is added to a volume of another solution
in order to determine its concentration.

toughness
Ability to withstand shock and to be deformed without rupturing.

transcription
The unfolding of DNA and the production of an mRNA strand. This step takes place in the nucleus of the cell.

translation
Messenger RNA interacts with the ribosome and transfers RNA to produce a protein.

trigonal bipyramid
One atom at the center with 5 at the corners. Bond angles around the atom are not the same.

trigonal planar
The three fluorine atoms lie in a plane with the central boron atom.

triple point
Point where all three states of matter can exist simultaneously.

Tyndall Effect
The phenomenon in which light is scattered by very small particles in its path.
