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...

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...

What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

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.

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.
Most Popular
Acid
A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. Chemicals or substances having the property of an acid are said to be acidic.
Manometer
A two-armed barometer.
Dipole-dipole Interactions
Attractive interactions between polar molecules, that is, between molecules with permanent dipoles.
Electron Deficient Compounds
Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.
Secondary Standard
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
Binding Energy (nuclear binding energy)
The energy equivalent (E = mc^2) of the mass deficiency of an atom. where: E = is the energy in joules, m is the mass in kilograms, and c is the speed of light in m/s^2
Thermal Cracking
Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
Net Ionic Equation
Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
Metallic Conduction
Conduction of electrical current through a metal or along a metallic surface.
Turning iron nail into copper nail
This simple chemical experiment shows the so-called process of copper plating of metal products. Copper has the ability to deposit on a metal surface.
