10. Thaum huab cua electron nyob ib ncig ntawm ib lub molecule tsis faib symmetrically, ib lub molecule yog polar. 11. Chemical bonds muaj xws li ionic bonds thiab hydrogen bonds.
Thaum huab cua hluav taws xob tsis tau muab faib ua symmetrically lub molecule raug suav tias yog polar?
Intermolecular rog tshwm sim los ntawm kev sib cuam tshuam ntawm electron ntawm cov nyob sib ze molecules. Thaum huab cua hluav taws xob tsis tau faib symmetrically, lub molecule muaj qhov polarity. Cov ntawv cog lus tshuaj muaj xws li ionic bonds, metallic bonds, thiab atomic bonds. 3.)
Cov polarity ntawm ib yam khoom cuam tshuam li cas rau lub zog ntawm kev nyiam ntawm cov molecules?
Polar molecules sib dhos kom qhov kawg ntawm ib lub molecule cuam tshuam nrog qhov tsis zoo kawg ntawm lwm cov molecule. Tsis zoo li covalent bonds ntawm atoms nyob rau hauv ib lub molecule (intramolecular bonding), dipole-dipole kev sib cuam tshuam tsim kev nyiam ntawm cov khoom ntawm cov khoom(intermolecular attractions).
Yuav ua li cas electronegativity cuam tshuam rau lub zog ntawm lub cev?
Qhov txawv ntawm electronegativity ntawm ob lub atoms hauv daim ntawv cog lus txiav txim seb hom ntawv cog lus uas tsim. … Intermolecular rog, xws li dipole-dipole rog, London dispersion rog, thiab hydrogen bonds, yog qaug zog zog uas muaj nyob nruab nrab ntawm molecules.
Dab tsi yog qhov kev sib cuam tshuam molecular uas muaj zog tshaj plaws?
Lub zog muaj zog tshaj plaws yog hydrogen bonding, uas yog ib qho tshwj xeeb ntawm kev sib cuam tshuam ntawm dipole-dipole uas tshwm sim thaum hydrogen nyob ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine).

Thaum twg yog lub teeb hluav taws xob tsim hluav taws xob?
Lub teeb sodium siab tsawg tau tsim ua ntej hauv 1920 los ntawm Arthur H. Compton ntawm Westinghouse. Thawj lub teeb yog lub teeb puag ncig nrog ob lub electrodes ntawm txhua sab . HPS tau tsim thaum twg? HPS teeb tau tsim thiab qhia hauv 1968 ua qhov chaw siv hluav taws xob zoo rau sab nrauv, kev ruaj ntseg, thiab kev siv teeb pom kev zoo, thiab tshwj xeeb tshaj yog nyob rau hauv kev siv teeb pom kev zoo .
Nyob hauv lub tswb hluav taws xob lub tshuab hluav taws xob yog sib nqus thaum hloov pauv?
Thaum qhov hloov pauv (K) raug kaw, qhov hluav taws xob tam sim no dhau los ntawm lub roj teeb (U) los ntawm cov cua tshuab hluav taws xob. Nws tsim magnetic teb uas nyiam lub caj npab hlau ntawm tus npuaj teg, rub nws los muab lub tswb rau tus kais .
Thaum cov nqi hluav taws xob marginal txo qis tag nrho cov nqi hluav taws xob?
(b) Marginal utility, los ntawm kev txhais, qhia txog kev hloov pauv ntawm tag nrho cov nqi hluav taws xob. Yog li kev siv nyiaj marginal txo qis nrog kev siv ntau ntxiv, dhau los ua xoom thaum tag nrho cov nqi hluav taws xob yog qhov siab tshaj plaws, thiab yog qhov tsis zoo thaum tag nrho cov nqi hluav taws xob poob .
Yuav tsum tau hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob?
Kuv puas yuav tsum hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob? Ignition coils thiab spark plugs ua haujlwm zoo ua ke. … Tab sis yog tias koj tsuas yog hloov koj lub qhov hluav taws xob ua ib feem ntawm kev saib xyuas niaj hnub, nws tsis tsim nyog los hloov koj cov hluav taws xob hluav taws xob tib lub sijhawm tshwj tsis yog muaj cov cim qhia tias lawv ua tsis tau Yuav tsum hloov cov hluav taws xob hluav taws xob ntau npaum li cas?
Puas yog roj hluav taws xob hluav taws xob hluav taws xob zoo?
Central gas heating systems siv natural gas rau tsev sov. Kuv xav siv cov pa roj carbon monoxide tsis zoo rau lub hauv nruab nrab cua sov vim tias nws yooj yim, yooj yim, txhim khu kev qha, thiab ua haujlwm zoo dua. Thaum tshav kub kub uas los ntawm cov nkev ntuj pom tau tias sov dua li cua sov tawm ntawm lub hauv paus system .
