Rau binary ionic compounds ( ionic compounds uas tsuas muaj ob hom ntsiab), lub tshuaj sib xyaw yog npe los ntawm kev sau ntawv npe ntawm cation thawj zaug ua raws li cov npe ntawm anion. Piv txwv li, KCl, ib ionic compound uas muaj K+ thiab Cl- ions , yog npe poov tshuaj chloride.
Yog li ntawd, dab tsi yog peb lub ntsiab lus uas tsim ib qho anion?
Zoo thiab tsis zoo Ions: Cations thiab Anions
| Tsev neeg | Element |
|---|---|
| VIA | Oxygen |
| Sulfur | Sulfide anion |
| VIIA | Fluorine |
| Chlorine | Chloride anion |
Tom qab ntawd, lo lus nug yog, koj yuav txheeb xyuas qhov anion li cas? Anion Kev ntsuam xyuas thiab kev soj ntsuam Dilute nitric acid yog thawj zaug ntxiv kom tshem tawm cov ions cuam tshuam. Tom qab ntawd, ib qho tshuaj aqueous yog ntxiv rau cov qauv kuaj. Xaiv ib tug aqueous tov uas yuav ua precipitate nrog lub anion nyob rau hauv cov qauv xeem. Yog tias precipitate tsim, peb tuaj yeem lees paub qhov txheeb xyuas ntawm anion.
Ua raws li qhov xav tau, lub npe ntawm ionic compound PbSO3 yog dab tsi?
Lead (II) Sulfite PbSO 3 Molecular Luj - EndMemo.
Puas yog Cl A cation lossis anion?
Cov hlau hlau feem ntau tsim cations thiab cov khoom tsis yog hlau feem ntau tsim anions . Piv txwv li hauv NaCl, lub cation , Na+, yog tsim los ntawm kev poob ntawm ib qho hluav taws xob los ntawm pawg 1 hlau sodium. Thaum lub tshuaj chlorine anion , Cl -, yog tsim los ntawm qhov nce ntawm ib qho hluav taws xob los ntawm pawg 7 uas tsis yog hlau tshuaj chlorine atom.

Yuav ua li cas cov nroj tsuag tau txais cov khoom uas lawv xav tau rau kev loj hlob?
Cov nroj tsuag tau txais cov ntaub ntawv uas lawv xav tau rau kev loj hlob thiab kev loj hlob feem ntau los ntawm cov txheej txheem hu ua photosynthesis. Photosynthesis xav tau lub teeb lub zog (los ntawm lub hnub), huab cua (carbon dioxide), thiab dej los tsim cov suab thaj (glucose) thiab oxygen
Yuav ua li cas koj hloov cov units me mus rau cov units loj?
Hloov cov chav me me mus rau cov chav loj loj dua chav tsev loj. Txhawm rau hloov los ntawm chav tsev loj dua mus rau ib qho me me, sib npaug. Txhawm rau hloov los ntawm chav tsev me mus rau qhov loj dua, faib
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Organic compounds thiab inorganic compounds yog dab tsi?
Lub ntsiab sib txawv yog nyob rau hauv lub xub ntiag ntawm ib tug carbon atom; cov organic tebchaw yuav muaj cov pa roj carbon atom (thiab feem ntau yog hydrogen atom, tsim hydrocarbons), thaum yuav luag tag nrho cov inorganic tebchaw tsis muaj ib qho ntawm ob lub atoms. Meanwhile, inorganic tebchaw muaj xws li cov ntsev, hlau, thiab lwm yam elemental compounds
Puas yog tag nrho cov ionic compounds muaj cov qauv lattice?
Ib qho ionic compound yog cov qauv loj heev ntawm cov ions. Cov ions muaj qhov tsis tu ncua, rov ua dua tshiab hu ua ionic lattice. Qhov no yog vim li cas cov khoom ioniccompounds tsim cov muaju nrog cov duab tsis tu ncua
