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
In Lewis structures the goal is to make almost all atoms have an octet. This means that they will have access to 8 electrons regularly, even if they do have to share some of them.
Lyuis strukturalarida maqsad barcha atomlarning oktet hosil qilishiga qaratiladi. Bu, atomlar ba'zi elektronlarini almashishlari kerak bo'lsada, ular muntazam ravishda 8 ta elektrondan foydalanish imkoniyatiga ega bo'ladi, degan ma'noni anglatadi.
A carbohydrate that cannot be decomposed into simpler carbohydrates by hydrolysis .
Gidrolizga uchramaydigan eng oddiy uglevod.
A type of covalent bond in which the electron density is concentrated around the line bonding the atoms.
Kovalent bog'ning bir turi bo'lib, bunda elektron zichligi atomlar bog'langan chiziq atrofida jamlanadi.
The number of moles of solute (the material dissolved) per liter of solution. Used to express the concentration of a solution.
1 litr erituvchida erigan moddaning mollar soni. Eritmaning konsentratsiyasini ifodalashda foydalaniladi.
Energy is an abstract property associated with the capacity to do work .
Energiya ishni bajarish uchun zarur quvvat bo'lib, u mavhum tushuncha hisoblanadi.
Forces within molecules. Forces caused by the attraction and repulsion of charged particles.
Molekulaning ichidagi kuchlar. Mazkur kuchlar, zaryadlangan zarrachalarning tortilishi va itarilishi natijasida hosil bo'ladi.
The combined mass (as given on the periodic table) of all the elements in a compound.
Birikma tarkibidagi barcha elementlarning massalari (davriy jadvalda berilgan) yig'indisi molekulyar massani beradi.
Number of events in a given unit of time. When describing a moving wave, means the number of peaks which would pass a stationary point in a given amount of time.
Berilgan vaqt birliklarida voqealarning soni. Harakatlanayotgan to'lqin deb, statsionar nuqtani berilgan vaqt oralig'ida o'tgan piklar soniga aytiladi.
Dispersion is an intermolecular attraction force that exists between all molecules. These forces are the result of the movement of electrons which cause slight polar moments. Dispersion forces are generally very weak but as the molecular mass increases so ...
Dispersion kuch barcha molekulalar orasida mavjud bo'lgan molekulalararo tortishish kuchidir. Bu kuchlar engil qutb daqiqalarni sabab elektronlar harakati natijasidir. Dispersion kuchlar odatda juda zaif, lekin molekulyar massa oshishi bilan, ularning kuchi ...
