A naturally occurring amino acid and building block of proteins with a sulfur-containing side chain.
Oltingugurt tutgan yon zanjirga ega, oqsil tarkibiga kiruvchi tabiiy aminokislota.
A particle found in the nucleus of an atom and is almost identical in mass to a proton, but carries no electric charge.
Yadroning, massasi proton massasiga juda o'xshash, lekin hech qanday zaryadga ega bo'lmagan tarkibiy qismi.
1. Of or pertaining to moles . 2. An synonym for molarity ; for example, a "six molar solution of hydrochloric acid" contains 6 moles of HCl per liter of solution.
1. Mol so'zidan olingan. 2. Molyarlik tushunchasiga sinonim; misol uchun, "xlorid kislotaning olti molyarli eritmasi" deganda har bir litr eritmada 6 mol HCl eriganligi tushuniladi.
An element is a substance composed of atoms with identical atomic number . The older definition of element (an element is a pure substance that can't be decomposed chemically) was made obsolete by the discovery of isotopes .
Atom raqamlari bir xil bo'lgan atomlardan tashkil topgan modda. Elementga berilgan avvalgi ta'rif (element bu kimyoviy bo'linmas toza modda) izotopning kashf qilinishi bilan o'z kuchini yo'qotdi.
An atom or molecule that has acquired a charge by either gaining or losing electrons. An atom or molecule with missing electrons has a net positive charge and is called a cation ; one with extra electrons has a net negative charge and is called an anion .
Elektron yo'qotishi yoki biriktirishi hisobiga zaryadga erishgan atom yoki molekula. Elektron yo'qotgan atom yoki molekula musbat zaryadga ega bo'lib, kation deyiladi; qo'shimcha elektronga ega bo'lgan atom yoki molekula esa manfiy zaryadga ega bo'lib, anion ...
1. having no net electrical charge. Atoms are electrically neutral; ions are not. 2. A solution containing equal concentrations of H+ and OH-.
1. elektr zaryadga ega bo'lmaslik. Atomlar elektr neytral bo'ladi; ionlar esa aksincha. 2. eritma tarkibida ekvivalent jihatdan teng miqdordagi H+ va OH- lar mavjud bo'ladi.
The coefficients given before substances in a balanced chemical equation . For example, the stoichiometric coefficient of carbon dioxide in the following reaction is 4: 2 C2H6(g) + 7 O2(g) 4 CO2 + 6 H2O
Tenglashtirilgan kimyoviy tenglamalarda moddalarning oldiga qo'yilgan koeffisiyent. Masalan, quyidagi tenglamada uglerod (II) oksidining oldiga qo'yilgan 4 raqami uning koeffisientidir: 2C2H6(g) + 7O2(g)= 4CO2 + 6H2O
The total number of protons and neutrons in an atom or ion. In nuclide symbols the mass number is given as a leading superscript. In isotope names (e.g. carbon-14, sodium-23) the mass number is the number following the element name.
Atom yoki iondagi proton va neytronlarning umumiy soni. Atom og'irligi atom ko'rsatkichlari ichida yetakchi rol o'ynaydi. Izotop nomlaridagi (masalan, uglerod-14, natriy-23) ko'rsatilgan sonlar berilgan elementning og'irliklaridir.
SI unit for amount of substance, defined as the number of atoms in exactly 12 g of carbon-12. One mole of a molecular compound contains Avogadro's number molecules and has a mass equal to the substance's molecular weight, in grams.
Uglerod-12 izotopining aynan 12 grammidagi atomlar soni kabi aniqlanadigan moddaning miqdori uchun SI birligi. Har qanday molekulyar tuzilishli 1 mol modda Avagadro soniga teng molekulalarga va molekulyar massaga teng og'irlikka to'g'ri keladi.
A chemical change in which one compound aquires H+ from another. The compound that receives the hydrogen ion is the base; the compound that surrenders it is an acid.
Bir birikma boshqa birikmadan H+ qabul qilib olgandagi kimyoviy o'zgarish. Vodorod qabul qiluvchi birikma asos, beruvchi birikma kislota deyiladi.
