CHEMISTRY GLOSSARY
barometer → barometar
Barometer is an instrument that measures atmospheric pressure. A mercury barometer is a closed tube filled with mercury inverted in a mercury reservoir. The height of the mercury column indicates atmospheric pressure (with 1 atm = 760 mm of mercury). An aneroid barometer consists of an evacuated container with a flexible wall. When atmospheric pressure changes, the wall flexes and moves a pointer which indicates the changing pressure on a scale.
biochemistry → biokemija
Biochemistry is the study of the chemistry of living organisms, especially the structure and function of their chemical components (principally proteins, carbohydrates, lipids and nucleic acids).
bioelement → bioelement
Bioelement is any chemical element that is found in the molecules and compounds that make up living organism.
carbon dating → određivanje starosti radioaktivnim ugljikom
Carbon dating is used to the time passed since a living organism died. It is based on measuring the quantity of isotope of carbon-14 that is contained in all living organisms.
contaminant → kontaminat
Contaminants are any physical, chemical, biological, or radiological substance or matter in water that may be harmful to human health or which degrade the palatability of water.
invertase → invertaza
Invertase (sucrase, saccharase, beta-fructofuranosidase) is an enzyme present in yeast and in the intestinal juice of animals that catalyze the hydrolysis of table sugar (sucrose, saccharose) to the simple sugars, glucose and fructose. This equimolar mixture of glucose and fructose is called invert sugar.
bismuth → bizmut
Bismuth was discovered by Claude Geoffroy (France) in 1753. The origin of the name comes from the German words Weisse Masse meaning white mass; now spelled wismut and bisemutum. It is hard, brittle, steel-grey metal with a pink tint. Stable in oxygen and water. Dissolves in concentrated nitric acid. Bismuth can be found free in nature and in minerals like bismuthine (Bi2S3) and in bismuth ochre (Bi2O3) Main use is in pharmaceuticals and low melting point alloys used as fuses.
crude oil → sirova nafta
Crude oil (petroleum) is a fossil fuel formed from plant and animal remains many million of years ago. It is occasionally found in springs or pools but is usually drilled from wells beneath the earth’s surface. Crude oil is a mixture of hydrocarbons with small quantities of other chemicals such as sulphur, nitrogen and oxygen. Crude is the raw material which is refined into petrol, heating oil, jet fuel, propane, petrochemicals, and other products.
