  • 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...

  • 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...

  • Chemistry of the sky

    Chemistry can teach us about the composition of celestial bodies and determine their age.

  • 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...

  • 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.

Biodegradability

The ability of a substance to be broken down into simpler substances by bacteria.

 

Two chemistry egg tricks

The French have a saying: "You cannot cook an omelet without breaking eggs."Chemists hearing this proverb totally disagree. There is nothing easier than cleaning an egg without breaking its shell.
Probably our readers have already guessed how to do this, as it’s known that the hard shell of the egg is carbon dioxide, like chalk and marble.

Thermodynamics

The study of the energy transfers accompanying physical and chemical processes.

Daughter Nuclide

Nuclide that is produced in a nuclear decay.

 

Standard Entropy

The absolute entropy of a substance in its standard state at 298 K.

Coordination Isomers

Isomers involving exchanges of ligands between complex cation and complex anion of the same compound.

Do you know: some mosquitoes bite people because of their clothes

If you have ever been bitten by a mosquito, someone nearby surely gave you an explanation of why the nasty insect decided to spoil your day. Maybe they told you that you smelt good, or you had a certain type of blood or that in that shirt you looked like a potential victim.

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.

Deposition

The direct solidification of a vapor by cooling, the reverse of sublimation.
