Txawm tias ionic siv lead ua yog tuav ua ke los ntawm electrostatic zog , cov ions sib cais thaum cov khoom dissolves. Ions muaj zog attracted rau qhov kawg ntawm polar molecules uas muaj nqi opposite rau cov ntawm cov ions.
Tsis tas li lo lus nug yog, yuav ua li cas rau ob hom rog hauv cov iav siv lead ua thaum lawv yaj lossis yaj?
Tab sis thaum lub ionic compound yaj , tus nqi ions yog dawb txav mus los. Yog li ntawd, molten ionic compounds ua hluav taws xob. Thaum a siv lead ua ntawm ib qho ionic compound yaj Hauv dej, cov ions sib cais. Ib zaug ntxiv, cov ions yog dawb txav mus - yog li kev daws teeb meem ntawm ionic compound hauv dej kuj ua hluav taws xob.
Dab tsi quab yuam rhuav cov ionic siv lead ua sib nrug? Txawm li cas los xij, thaum qhov ntawd tshwm sim, nws coj ions ntawm tib tus nqi ib sab ntawm ib leeg (saib daim duab hauv qab). Lub siab phem zog nruab nrab zoo li-them nqi ions ua rau siv lead ua ua tawg. Thaum ib ionic siv lead ua tawg , nws nyiam ua li ntawd raws li cov dav hlau du vim yog kev ua haujlwm tsis tu ncua ntawm cov ions.
Ua raws li qhov no hauv kev xav, vim li cas ions ua cov muaju?
Cov ions muaj ib tug li niaj zaus, rov hais dua kev npaj hu ua ib ionic daim kab xev. Lub lattice yog tsim vim lub ions sib nyiam thiab daim ntawv ib txwm qauv nrog oppositely them ions nyob ib sab. Qhov no yog vim li cas khov ionic tshuaj sib xyaw daim ntawv crystals nrog cov duab tsis tu ncua.
Vim li cas cov ionic nkig tawg tawg thaum ntaus?
Kua muag ionic compounds hu ua electrolytes. Cov pob txha pob txha ntawm ionic compounds yog nkaws . Lawv feem ntau yuav tawg dua li khoov thaum ntaus . Vim li ntawd, ionic crystals nyiam tawg yooj yim.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim thaum ib tug muaj zog acid yaj nyob rau hauv dej?
Thaum cov kua qaub yaj hauv dej, ib qho proton (hydrogen ion) raug xa mus rau cov dej molecule los tsim cov hydroxonium ion thiab qhov tsis zoo ion nyob ntawm seb cov kua qaub koj pib li cas. Cov kua qaub muaj zog yog ib qho uas yuav luag 100% ionised hauv kev daws. Lwm cov tshuaj muaj zog muaj xws li sulfuric acid thiab nitric acid
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Yuav ua li cas tshwm sim thaum koj ntxiv ib tug qaug zog acid rau dej?
Thaum cov kua qaub uas tsis muaj zog ntxiv rau hauv dej, cov ntaub ntawv sib npaug sib npaug hauv cov kua qaub molecules, HA (aq), hnov mob nrog cov dej ua kua los tsim cov aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum cov kua qaub molecules poob H + ions rau dej
