Lub npe poly- txhais tau tias "ntau," hauv Greek, tab sis txawm tias ions ntawm ob lub atom feem ntau hu ua polyatomic. Piv txwv li: Carbonate (CO 3 2-), sulphate (SO 42-), nitrate - TSIS MUAJ 3 - thiab hydroxide ions hydroxide ions Hydroxide yog ib qho diatomic anion nrog tshuaj formula OH- Nws muaj cov pa oxygen thiab hydrogen. atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa ib qho hluav taws xob tsis zoo. Nws yog ib qho tseem ceeb tab sis feem ntau me me ntawm cov dej. Nws ua haujlwm raws li lub hauv paus, ligand, nucleophile, thiab catalyst. https://en.wikipedia.org › wiki › Hydroxide
Hydroxide - Wikipedia
OH- yog txhua yam polyatomic ions.
Dab tsi yog polyatomic ions muab piv txwv?
Polyatomic ions yog ions uas muaj ntau dua ib lub atom Piv txwv li, nitrate ion, NO3-, muaj ib lub nitrogen atom thiab peb oxygen atoms. Cov atoms nyob rau hauv ib tug polyatomic ion feem ntau yog covalently bonded rau ib leeg, thiab yog li ntawd nyob ua ke raws li ib tug, them unit. Txoj Cai 1.
Dab tsi yog polyatomic ions muab ob qho piv txwv ntawm nws?
Dab tsi yog polyatomic ions? Muab ob qho piv txwv
- Polyatomic atoms yog pawg ntawm atoms uas muaj nuj nqis rau lawv.
- Vim li no ions raug them cov khoom.
- Example:
- Sulphate ion --- SO4⁻²
- sulphate ion muaj atoms ntawm leej faj thiab oxygen atoms nrog tus nqi ntawm -2.
- Carbonate Ion - CO3⁻²
Dab tsi yog polyatomic ions muab ob qho piv txwv Brainly?
Polyatomic ions raws li lub npe qhia yog cov ions uas muaj ntau tshaj ib lub atom. Cov atoms yuav zoo ib yam lossis sib txawv. Piv txwv li: Ammonium ions, Carbonate ions, cyanide ions, chlorite ions yog qee qhov piv txwv ntawm polyatomic ions.
Dab tsi yog polyatomic ions Class 9?
Polyatomic ions: Cov ions uas tau tsim los ntawm pawg ntawm cov atoms koom nrogyog hu ua polyatomic ions. Cov ions tseem hu ua polyatomic ions. Rau eg. Ammonium ion NH4 +, yog ib qho kev sib xyaw ion uas yog tsim los ntawm ob hom atoms koom ua ke nitrogen thiab hydrogen.

Ib qho piv txwv ntawm kev ua piv txwv yog dab tsi?
Raws li qhov piv txwv ntawm kev ua qauv zoo, xav tias hauv cov pejxeem ntawm 10,000 tus neeg, tus kws txheeb cais xaiv txhua 100 tus neeg rau kev kuaj. Cov sijhawm piv txwv kuj tseem tuaj yeem ua tau zoo, xws li xaiv tus qauv tshiab los kos los ntawm txhua 12 teev .
Dab tsi yog exoenzyme muab ob qho piv txwv?
Exoenzymes muaj ntau lub hom phiaj thiab ntau hom muaj nyob rau hauv degrade feem ntau ntawm cov organic teeb meem. Qee qhov piv txwv ntawm exoenzymes xws li proteases, amylases, xylanases, pectinases, cellulases, chitinases, mannases, ligninases thiab lipases .
Dab tsi yog oscillatory motion muab ob qho piv txwv?
Oscillatory motion yog txhais raws li kev txav mus los ntawm lub cev txog nws txoj haujlwm ruaj khov. Oscillatory motion yog ib hom kev txav mus los. Piv txwv ntawm oscillatory motion yog vibrating hlua, viav vias viav vias thiab lwm yam . oscillation yog ob qho piv txwv?
Puas yog piv txwv ntawm kev piv txwv?
Piv txwv ntawm kev tuag metaphors tuag metaphors Ib qho piv txwv tuag yog ib daim duab ntawm kev hais lus uas tau ploj qhov qub duab ntawm nws lub ntsiab lus los ntawm kev siv dav, rov ua dua, thiab siv nrov. Cov lus piv txwv tuag feem ntau yog qhov tshwm sim ntawm kev hloov pauv hauv kev hloov pauv hauv kev hloov pauv ntawm ib hom lus, txheej txheem hu ua kev hais lus ntawm kev ua piv txwv.
Puas yog cov qauv piv txwv zoo ib yam li kev ua piv txwv?
Lub hom phiaj sampling yog siv dav hauv kev tshawb fawb zoo rau kev txheeb xyuas thiab xaiv cov ntaub ntawv nplua nuj cuam tshuam txog qhov tshwm sim ntawm kev txaus siab. Txawm hais tias muaj ntau ntau lub hom phiaj ua piv txwv, cov qauv qauv zoo li tau siv feem ntau hauv kev tshawb fawb siv.
