H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.

Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.

Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.

Hybridization

Mixing a set of atomic orbitals to form a new set of atomic orbitals with the same total electron capacity and with properties and energies intermediate between those of the original unhybridized orbitals.

Amorphous Solid

A noncrystalline solid with no well-defined ordered structure.

Active Metal

Metal with low ionization energy that loses electrons readily to form cations.

Hund's Rule

All orbitals of a given sublevel must be occupied by single electrons before pairing begins.

Potential Energy

Energy that matter possesses by virtue of its position, condition or composition.

Cathode

Electrode at which reduction occurs in a cathode ray tube, the negative electrode.

Henry's Law

The pressure of the gas above a solution is proportional to the concentration of the gas in the solution.

Solvolysis

The reaction of a substance with the solvent in which it is dissolved.

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.

Cyclotron

A device for accelerating charged particles along a spiral path.
