Vim tias cov tshuaj molecular yog tsim los ntawm nruab nrab molecules, lawv cov hluav taws xob conductivity feem ntau tsis zoo, txawm nyob rau hauv cov khoom los yog kua. … Thaum molten, txawm li cas los xij, nws tuaj yeem ua hluav taws xob vim nws cov ions tuaj yeem txav mus los ntawm cov kua (Daim duab 6.2.
Cov kua molecular puas ua tau hluav taws xob?
Molecular compounds tsis dissociate rau hauv ions thiab yog li tsis ua hluav taws xob hauv kev daws. Hluav taws xob conductivity ntawm lub compound nyob rau hauv kua daim ntawv. … Covalent molecular compounds tsis ua, vim lawv feem ntau tsis hloov electrons tshwj tsis yog lawv hnov mob.
Koj paub li cas yog lub molecule ua hluav taws xob?
Txoj hauv kev yooj yim tshaj plaws los txiav txim siab seb qhov sib xyaw puas tuaj yeem ua tau tam sim no yog txhawm rau txheeb xyuas nws cov qauv molecular lossis cov khoom sib xyaw. Cov tshuaj uas muaj zog conductivity dissociate tag nrho rau hauv them atoms los yog molecules, los yog ions, thaum yaj nyob rau hauv dej. Cov ions no tuaj yeem txav mus thiab nqa tam sim no tau zoo.
Puas covalent compounds ua hluav taws xob?
Covalent compounds (khoom, kua, kua) tsis ua hluav taws xob. Cov hlau thiab cov pa roj carbon (graphite) yog cov khoom siv hluav taws xob tab sis cov hlau tsis yog hlau yog cov hluav taws xob hluav taws xob. … Ionic tebchaw ua kua los yog thaum nyob rau hauv kev daws raws li cov ions tsis pub txav mus los.
Vim li cas molecules tsis ua hluav taws xob?
Yooj yim molecules muaj nozuag qhia tag nrho tus nqi, lossis cov khoom them uas tuaj yeem sib cais, yog li cov tshuaj molecular yooj yim tsis tuaj yeem ua hluav taws xob, txawm tias thaum ua kua lossis yaj hauv dej. … Thaum tej yam yooj yim molecular yaj los yog boil, lawv cov tsis muaj zog intermolecular rog yeej kov yeej, tsis muaj zog covalent bonds.
