Concentration of a substance in a mixture measured as moles of the substance per mole of mixture. For example, the mole fraction of oxygen in air is about 0.21, which means that 1 mol of air contains about 0.21 mol O2.
Aralashma tarkibidagi birikmaning konsentratsiyasi bo'lib, birikma mollarining aralashma moliga nisbati bilan aniqlanadi. Misol uchun, havo tarkibidagi kislorodning mol ulushi 0,21 ga teng, buning ma'nosi 1 mol havo 0,21 mol O2 ni o'z ichiga olgan, ...
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 ...
Density is the mass per unit volume of any substance. Its units are kilograms per cubic metre.
Zichlik har qanday moddaning hajm birligidagi massasiga aytiladi. U kilogrammning metr kubga nisbatida ifodalanadi.
Energy is an abstract property associated with the capacity to do work .
Energiya ishni bajarish uchun zarur quvvat bo'lib, u mavhum tushuncha hisoblanadi.
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.
A substance that is made up of two or more chemically bonded elements.
Ikki yoki undan ortiq kimyoviy bog'langan elementlardan tashkil topgan modda.
A process that absorbs heat. The enthalpy change for an endothermic process has a positive sign.
Issiqlik yutilishi bilan boradigan jarayonlar. Endotermik jarayon uchun entalpiya ko'rsatkichi musbat bo'ladi.
Processes or events that have altered the fundamental structure of something.
Biror bir jismning fundamental strukturasining o'zgarish hodisasi.
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 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.
