Collision Theory

Theory of reaction rates that states that effective collisions between reactant molecules must occur in order for the reaction to occur.

Base

A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.

Density

Density is the ratio b/w Mass and Volume: D=M/V

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.

Dissociation

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

Oxidation-reduction Reactions

Reactions in which oxidation and reduction occur, also called redox reactions.

The most expensive metal in the world

Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

van der Waals' Equation

An equation of state that extends the ideal gas law to real gases by inclusion of two empirically determined parameters, which are different for different gases.

Emulsifying Agent

A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.

Homogeneous Mixture

A mixture which has uniform composition and properties throughout.
