Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

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...

Ozone
We breathe 24 hours a day, 7 days a week, consuming about 25 kg of air every day. It turns out that we practically predetermine our health by the air we breathe.

Bonding Orbital
A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.
Reaction Quotient
The mass action expression under any set of conditions (not necessarily equlibrium), its magnitude relative to K determines the direction in which the reaction must occur to establish equilibrium.
Crystal Field Theory
Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.
Ideal Gas
A hypothetical gas that obeys exactly all postulates of the kinetic-molecular theory.
Fluorescence
Absorption of high energy radiation by a substance and subsequent emission of visible light.
Concentration
Amount of solute per unit volume or mass of solvent or of solution.
DP number
The degree of polymerization, the average number of monomer units per polymer unit.
Catenation
Bonding of atoms of the same element into chains or rings.
The bonding together of atoms of the same element to form chains.
The ability of an element to bond to itself.
Boyle's Law
At constant temperature the volume occupied by a definite mass of a gas is inversely proportional to the applied pressure.
Electronic Geometry
The geometric arrangement of orbitals containing the shared and unshared electron pairs surrounding the central atom of a molecule or polyatomic ion.
