  • 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...

    Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...

  • 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...

Coordination Compound or Complex

A compound containing coordinate covalent bonds.

Ampere

Unit of electrical current, one ampere equals one coulomb per second.

 

Calorimeter

A device used to measure the heat transfer between system and surroundings.

Zone Refining

A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.

Flammable

A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).

xylan

The pentosan occurring in woody tissue that hydrolyzes to xylose: used as a source of furfural.

Metallic Bonding

Bonding within metals due to the electrical attraction of positively charges metal ions for mobile electrons that belong to the crystal as a whole.

Suspension

A heterogeneous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction.

Heterogeneous Catalyst

A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.

Entropy

A thermodynamic state or property that measures the degree of disorder or randomness of a system.
