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...

Spectral Line
Any of a number of lines corresponding to definite wavelengths of an atomic emission or absorption spectrum, represents the energy difference between two energy levels.
Boiling Point
The temperature at which the vapor pressure of a liquid is equal to the applied pressure, also the condensation point
Autoionization
An ionization reaction between identical molecules.
Boron Hydrides

yield
The quantity of product formed by the interaction of two or more substances, generally expressed as a percentage of the quantity obtained to that theoretically obtainable.
Valence Shell Electron Pair Repulsion Theory
Assumes that electron pairs are arranged around the central element of a molecule or polyatomic ion so that there is maximum separation (and minimum repulsion) among regions of high electron density.
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.
History of diamonds
Diamond has been known for about 5 thousand years. Historians suggest that it was first discovered in India in river placers. It has long been credited with magical properties, and the largest famous crystals and products from them are shrouded in a halo of mystical legends.
Heat of Solution
The amount of heat absorbed in the formation of solution that contains one mole of solute, the value is positive if heat is absorbed (endothermic) and negative if heat is released (exothermic).
