Properties of a solution that depend only on the number of particles dissolved in it, not the properties of the particles themselves. The main colligative properties addressed at this web site are boiling point elevation and freezing point depression.
Eritmaning kolligativ xossalari eritmani tashkil etuvchi zarrachalar xossalariga emas, balki mazkur zarrachalar soniga bog'liqdir. Asosiy kolligativ xossalar qaynash nuqtasining oshishi va muzlash nuqtasining pasayishi veb-sahifalariga yo'naltirilgan.
The smallest particle of an element or compound that retains the chemical properties of the element or compound. A molecule is a collection of chemically bound atoms with characteristic composition and structure. Making or breaking bonds in a molecule ...
Element yoki aralashmaning barcha xususiyatlarini o'zida tutuvchi, element yoki aralashmaning eng kichik zarrachasi. Molekula xarakterli tarkib va tuzilishga ega, kimyoviy bog'langan atomlar yig'indisidir. Molekulada bog'lar hosil bo'lishi yoki uzilishi yangi ...
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
Enthalpy (H) is defined so that changes in enthalpy ( H) are equal to the heat absorbed or released by a process running at constant pressure. While changes in enthalpy can be measured using calorimetry, absolute values of enthalpy usually cannot be ...
Entalpiyaning ta'rifiga ko'ra, uning o'zgarishi bosim doimiy bo'lgan holatda yutilgan yoki ajratilgan issiqlikka tengdir. Entalpiyaning o'zgarishlar oralig'ini kalorimetr yordamida o'lchash mumkin bo'ls-da, uning mutlaq qiymatini o'lchash mumkin emas. ...
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.
Devices that move electrons in or out of a solution by conduction.
Elektronlarni eritmaning ichiga yoki tashqarisiga ta'sirlanish natijasida harakatlantiradigan qurilma.
Empirical formulas show which elements are present in a compound, with their mole ratios indicated as subscripts. For example, the empirical formula of glucose is CH2O, which means that for every mole of carbon in the compound, there are 2 moles of hydrogen ...
Empirik formulalarda modda qaysi element atomlaridan necha moldan tuzilganligini ko'rsatadi. Misol uchun, glyukozaning empirik formulasi CH2O bo'lib, bu formulaga ko'ra har 1 mol uglerodga 2 mol vodorod va 1 mol kislorod to'gri kelishini ko'rsatadi.
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.
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.
Strong type of intermolecular dipole-dipole attraction. Occurs between hydrogen and F, O or N.
Molekulalararo dipol-dipol ta'sirning kuchli turi. Vodorod bilan F, O yoki N o'rtasida shakllanadi.
