  • Features of the Scanning Tunneling Microscope

    The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

  • 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...

  • Chemistry of the sky

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

  • 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

Weak Electrolyte

A substance that conducts electricity poorly in a dilute aqueous solution.

Complex Ions

Ions resulting from the formation of coordinate covalent bonds between simple ions and other ions or molecules.

Bond Order

Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.

Coulometry

The quantitative application of Faraday's Law to the analysis of materials. The current and time are the usual variables measured.

Raoult's Law

The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.

Sigma Orbital

Molecular orbital resulting from head-on overlap of two atomic orbitals.

Ore

A natural deposit containing a mineral of an element to be extracted.

Bronsted-Lowry Acid

A proton donor.

Critical Point

The combination of critical temperature and critical pressure of a substance.

Heavy Water

Water containing deuterium, a heavy isotope of hydrogen.
