A class of bitter-tasting, basic organic compounds with nitrogen-containing rings. Alkaloids often have powerful effects on living things. Examples are cocaine, nicotine, strychnine, caffeine, and morphine.
Tarkibida azotli halqa tutuvchi, achchiq ta'mli organik asos birikmalar. Alkaloidlar asosan jonli narsalarga kuchli ta'sir etadi. Alkaloidlarga kokain, nikotin, strixnin, kafein va morfinlarni misol qilib keltirish mumkin.
Condensation products of aromatic amines and aldehydes forming azomethines substituted on the N atom, containing the general formula R-N:CHR.
Umumiy R-N:CHR formulaga ega, N atomi orqali azometin o'rinbosarlarini hosil qiluvchi, aromatik amin va aldegidlarning kondensatsiyasi mahsuloti.
A colorless, odorless, flammable gas, found in petroleum and natural gas. It is used as a fuel and as a raw material for building more complex organic molecules. Propane is the third member of the alkane series.
Neft va tabiiy gaz tarkibidagi rangsiz, hidsiz, yonuvchan gaz. U yoqilg'i va turli murakkab organik molekulalarni olishda xomashyo sifatida ishlatiladi. Propan alkanlar gomologik qatorining uchinchi a'zosi hisoblanadi.
The expression giving the ratio between the products and reactants. The equilibrium expression is equal to the concentration of each product raised to its coefficient in a balanced chemical equation and multiplied together, divided by the concentration of the ...
Mahsulotlar va reaktivlar o'rtasidagi nisbatni ifodalaydi. Muvozanat har bir mahsulotning konsentratsiyalari,koeffitsienti darajasiga ko'tarilgan holda ko'paytmasining, har bir reaksiyaga kirishayotgan moddalar konsentratsiyalari, koeffitsientlari darajasiga ...
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.
A property that can be measured without changing the chemical composition of a substance.
Bir moddaning kimyoviy tarkibini o'zgartirmagan holda o'lchanishi mumkin bo'lgan xususiyati.
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.
When the reactants and products are in a constant ratio. The forward reaction and the reverse reactions occur at the same rate when a system is in equilibrium.
Reaktivlar va mahsulotlar doimiy nisbatda bo'lgan holat. Tizim muvozanat holatda bo'lganda to'g'ri va teskari reaksiya tezliklari o'zaro teng bo'ladi.
Occurs when the moles of acid equal the moles of base in a solution.
Kislota va ishqorning mollari o'zaro teng bo'lganda erishiladigan nuqta.
The central part of an atom that contains the protons and neutrons. Plural nuclei.
Proton va neytronlarni o'z ichiga olgan atomning markaziy qismi.
