Koj puas paub tias polyatomic ion yog dab tsi? Txiav txim siab tus naj npawb oxidation ntawm txhua lub atom hauv lub ion . Piv txwv li, xav txog hydroxide ion , uas muaj oxygen atom thiab hydrogen atom. Tus lej oxidation ntawm oxygen yog -2, thiab tus lej oxidation ntawm hydrogen yog +1. Ntxiv ua ke cov oxidation tooj ntawm tag nrho cov atoms nyob rau hauv lub polyatomic ion.
Hauv qhov no, tus nqi ntawm polyatomic ion carbonate yog dab tsi?
Cov carbonate ion muaj ib tug carbon atom thiab peb oxygen atoms thiab nqa tag nrho nqi ntawm 2-. Cov mis ntawm lub carbonate ion yog CO2-3. Lub atom ntawm a polyatomic ion yog nruj nreem khi ua ke thiab tag nrho ion coj raws li ib tug unit.
Dab tsi yog polyatomic ion yog c2h3o2?
Teb: Nyob rau hauv kev txiav txim, npe polyatomic cation (ammonium) thiab monatomic anion (sulfide). Lub npe yog ammonium sulfide.

Yuav ua li cas koj sau cov mis rau ib tug compound uas muaj ib tug polyatomic ion?
Txhawm rau sau cov qauv rau cov tebchaw uas muaj polyatomic ions, sau lub cim rau cov hlau ion ua raws li cov qauv rau polyatomic ion thiab sib npaug cov nqi. Txhawm rau sau npe ib qho chaw uas muaj polyatomic ion, hais cov cation ua ntej thiab tom qab ntawd cov anion
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog cov khoom ntawm phosphorous acid Dab tsi yog nws cov mis?
Phosphorous acid (H3PO3) tsim cov ntsev hu ua phosphites, kuj siv los txo cov neeg ua haujlwm. Nws yog npaj los ntawm dissolving tetraphosphorus hexoxide (P4O6) los yog phosphorus trichloride (PCl3) hauv dej
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
Dab tsi yog cov lej ntawm oxidation hauv polyatomic ion?
Cov lej ntawm cov lej oxidation hauv polyatomic ion yog sib npaug rau tus nqi ntawm cov ion. Tus lej oxidation ntawm sulfur atom hauv SO42- ion yuav tsum yog +6, piv txwv li, vim tias cov lej ntawm cov oxidation ntawm cov atoms hauv cov ion no yuav tsum sib npaug -2
