Yam dab tsi ntawm cov rog intermolecular muaj zog hauv lub xeev ua kua ntawm txhua yam hauv qab no? a) Neon (Ne) yog cov roj zoo. Cov zog uas muaj nyob ntawm noble gas atoms thiab nonpolar molecules yog hu ua dispersion zog . Yog li, hauv ua kua neon dispersion lub zog muaj zog.
Ib yam li ntawd, hom dab tsi ntawm kev quab yuam intermolecular active nyob rau hauv cov kua hauv lub xeev ntawm NE?
dispersion rog
Tsis tas li ntawd, cov kua dej puas muaj lub zog sib xyaw ua ke? Cov kua dej , solids, thiab gases. Cov kua dej flow vim intermolecular rog nruab nrab ntawm cov molecules tsis muaj zog txaus kom cia cov molecules txav ib ncig ntawm ib leeg. Intermolecular rog yog cov zog nruab nrab ntawm cov molecules nyob sib ze. Nyob rau theem molecular, kua muaj qee yam khoom ntawm gases thiab qee cov khoom khib nyiab.
Nyob rau hauv no, hom dab tsi ntawm lub zog intermolecular muaj nyob rau hauv cov kua roj thiab cov khib nyiab?
Roj particles tau tawg tawm ntawm cov intermolecular rog tias tuav kua thiab khoom ua ke. Lwm lub npe rau intermolecular rog yog van der Waals zog . Lawv suav nrog London Dispersion Kev quab yuam , dipole-cov zog , thiab hydrogen bonds.
Cov kua dej twg muaj zog tshaj plaws hauv lub cev?
Dej muaj lub zog intermolecular zog (hydrogen bonds) ntawm tag nrho cov khoom siv. Glycerine thiab methylated dab kuj muaj hydrogen bonds, tab sis cov no intermolecular rog me ntsis qaug zog dua hauv dej.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi yog txhais los ntawm cov rog intermolecular?
Intermolecular rog (IMF) yog cov rog uas sib haum xeeb ntawm cov molecules, nrog rau cov rog ntawm kev nyiam lossis kev tawm tsam uas ua rau ntawm cov molecules thiab lwm yam ntawm cov khoom nyob sib ze, piv txwv li. atoms los yog ions. Ob pawg ntawm cov quab yuam yog qhov tseem ceeb ntawm cov quab yuam uas nquag siv hauv molecular mechanics
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Lub xeev twg ntawm cov teeb meem twg muaj zog tshaj intermolecular rog ntawm attraction?
Raws li qhov kub thiab txias tseem poob qis, qhov teeb meem tsim muaj zog. Vim tias cov khoom tsis muaj zog kinetic, cov khoom tsis muaj 'lub sij hawm' txav mus los, cov khoom muaj 'lub sij hawm' kom nyiam. Yog li ntawd, cov khib nyiab muaj qhov muaj zog tshaj plaws intramolecular rog (vim lawv muaj qhov muaj zog tshaj plaws)
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
