Results 1171–1180 of 1369 for s.t.p.

volumetry → volumetrija

Volumetry consists of adding an equivalent amount of a reagent of exactly known concentration to the analyte. From stechiometrical proportion and added volume of reagent the quantity of matter in question can be calculated.

VSEPR → VSEPR

Valence shell electron pair repulsion theory (VSEPR) is a model that explains the shapes of molecules by assuming that electron pairs arrange themselves around atoms in a way that minimizes electron-electron repulsions.

vulcanisation → vulkanizacija

Vulcanisation (vulcanisation of rubber) is a process of combining rubber with sulphur or other substances that causes the polymer chains to crosslink, making them stronger and more elastic.

waste water → otpadna voda

Waste waters are waters which pour down from housing, public or industrial plants and are polluted with mineral and organic substances and microorganisms.

water softening → omekšavanje vode

Water softening is a process in which calcium and magnesium ions are removed from water. It is usually done by ion exchanger which exchanges removed ions with sodium ones.

watt → vat

Watt (W) is the SI derived unit of power. One watt is a power of one joule per second (W = J/s). It was named after the Scottish engineer James Watt (1736-1819).

wave → val

Wave is an oscillating motion that moves outward from the source of some disturbance (ripples running away from a pebble tossed in a pond). Waves transmit the energy of the disturbance away from its source.

wavefunction → valna funkcija

Wavefunction (Ψ) is a mathematical function that gives the amplitude of a wave as a function of position (and sometimes as a function of time and/or electron spin). Wavefunctions are used in chemistry to represent the behaviour of electrons bound in atoms or molecules.

wavelength → valna duljina

Wavelength is the distance between two neighbouring peaks of the electromagnetic wave.

weak base → slaba baza

Weak base is a base that only partially dissociates into ions in solution. Weak bases are weak electrolytes. Ammonia is an example of a weak base

NH₃(aq) + H₂O(l) →← NH₄⁺(aq) + OH^-(aq)
