Theoretical Yield

Maximum amount of a specified product that could be obtained from specified amounts of reactants, assuming complete consumption of limiting reactant according to only one reaction and complete recovery of product.

Heat

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

Evaporization

Vaporization of a liquid below its boiling point.

Varieties of garnet minerals

The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in elite jewelry.

Endothermic

Describes processes that absorb heat energy.

Inhibitory Catalyst

An inhibitor, a catalyst that decreases the rate of reaction.

Single Bond

Covalent bond resulting from the sharing of two electrons (one pair) between two atoms.

Band Theory of Metals

Theory that accounts for the bonding and properties of metallic solids.

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.

 

Heat of Fusion

The amount of heat required to melt one gram of solid at its melting point with no change in temperature. Usually expressed in J/g. The molar heat of fusion is the amount of heat required to melt one mole of a solid at its melting point with no change in temperature and is usually expressed in kJ/mol.
