  • Use of diamonds

    Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

  • Interesting facts about metals

    Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.

  • Protein Design: Automated protein discovery and synthesis

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

  • 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...

  • Diamonds Are Forever

    Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?

Second Law of Thermodynamics

The universe tends toward a state of greater diorder in spontaneous processes.

How is colored crystal made?

However, not everyone knows that in addition to the traditional transparent, there is still an unusually beautiful and spectacular colored crystal, which is obtained through the addition of various metal oxides into the glass. They give the crystal unusually noble shades of red, purple, blue, green and pink colors.

Chemical Equilibrium

A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.

Peroxide

A compound containing oxygen in the -1 oxidation state. Metal peroxides contain the peroxide ion, O22

Solubility Product Principle

The solubility product constant expression for a slightly soluble compound is the product of the concentrations of the constituent ions, each raised to the power that corresponds to the number of ions in one formula unit.

Water Equivalent

The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase.

Percentage Ionization

The percentage of the weak electrolyte that ionizes in a solution of given concentration.

Essential Oil

A plant extract that has a distinctive odour or flavour.

Born-Haber Cycle

A series of reactions (and accompanying enthalpy changes) which, when summed, represents the hypothetical one-step reaction by which elements in their standard states are converted into crystals of ionic compounds (and the accompanying enthalpy changes.)

Explosive limits

The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.
