  • 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...

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.

Enantiomer

One of the two mirror-image forms of an optically active molecule.

Solvent

The dispersing medium of a solution.

Heteronuclear

Consisting of different elements.

Alkyl Group

A group of atoms derived from an alkane by the removal of one hydrogen atom.

Strong Field Ligand

Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.

Lewis Base

Any species that can make available a share in an electron pair.

Three ways to make patina at home

The first way is ammonia patination. To do this, take a plastic container. Put a couple of paper or ordinary towels at the bottom. Moisten them with ammonia. Then sprinkle with large table salt.

Double Bond

Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.

Mass Action Expression

For a reversible reaction, aA + bB cC + dD the product of the concentrations of the products (species on the right), each raised to the power that corresponds to its coefficient in the balanced chemical equation, divided by the product of the concentrations of reactants (species on the left), each raised to the power that corresponds to its coefficient in the balanced chemical equation. At equilibrium the mass action expression is equal to K, at other times it is Q.[C]c[D]d [A]a[B]b = Q, or at equilibrium K.
