Results 1–4 of 4 for deuterij
deuterium lamp → deuterijeva svjetiljka
Deuterium or hydrogen lamp is used as a source of continuous radiation in UV part of the spectrum.
heavy water → teška voda
Water molecules are composed of two hydrogen atoms and one oxygen atom (H2O). If the hydrogen atoms of a water molecule are replaced by deuterium atoms, the result is heavy water (D2O). Deuterium differs from hydrogen by having one neutron in the nucleus of the atom. There is approx. one part in 5000 D2O in normal water and it can be concentrated by electrolysis. Heavy water has a higher boiling point (101.4 °C) and melts at 3.6 °C. Heavy water is 20/18=1.11 times heavier than ordinary water.
hydrogen → vodik
Hydrogen was discovered by Sir Henry Cavendish (England) in 1766. The origin of the name comes from the Greek words hydro and genes meaning water and generate. It is colourless, odourless gas, burns and forms explosive mixtures in air. Reacts violently with oxidants. Hydrogen is the most abundant element in the universe. Commercial quantities of hydrogen are produced by reacting superheated steam with methane or carbon. In lab work from reaction of metals with acid solutions or electrolysis. Most hydrogen is used in the production of ammonia and in metal refining. Also used as fuel in rockets. Its two heavier isotopes (deuterium and tritium) used respectively for nuclear fusion.
