Rau sau cov qauv rau Cov tshuaj muaj polyatomic ions , sau lub cim rau hlau ion ua raws li cov qauv rau cov polyatomic ion thiab sib npaug cov nqi. npe a Cov tshuaj muaj ib tug polyatomic ion , hais cov cation ua ntej thiab tom qab ntawd cov anion.
Hais txog qhov no, dab tsi yog qhov sib xyaw uas muaj polyatomic ion?
Polyatomic ions yog ions uas muaj ntau tshaj ib lub atom. Piv txwv li, nitrate ion , TSIS MUAJ3-, muaj ib tug nitrogen atom thiab peb oxygen atoms. Cov atoms hauv a polyatomic ion feem ntau yog covalently bonded rau ib leeg, thiab yog li ntawd nyob ua ke raws li ib leeg, them unit.
Tsis tas li ntawd, yog h2o yog polyatomic ion? yog polyatomic . Txawm tias cov organic molecules yog tag nrho polyatomic . Txawm tias yooj yim molecules zoo li dej H20 , hydrogen H2, nitrogen N2, oxygen O2, ozone O3, yog polyatomic.
Tom qab ntawd, dab tsi yog polyatomic ion muab piv txwv?
Polyatomic ion txhais: A polyatomic ion yog ib ion tsim los ntawm ob lossis ntau dua atoms. Piv txwv : Cov hydroxide cation (OH-) thiab phosphate cation (PO43-) yog ob leeg polyatomic ions.
Hom tshuaj twg yog CuSO4?
tooj liab sulfate inhibits kev loj hlob ntawm cov kab mob xws li E. coli. Tooj (II) sulfate yog cov tshuaj sib xyaw nrog cov mis CuSO4. Cov ntsev no muaj nyob rau hauv cov khoom sib txuas uas sib txawv ntawm lawv cov qib dej.

Yuav ua li cas yog rau cov ntaub ntawv nug uas yuav tsum tau kawm nyob rau hauv ib tug ua txhaum cai?
Qee yam ntawm cov ntaub ntawv nug uas raug kuaj xyuas cov ntaub ntawv pov thawj tau hais hauv qab no. • Xav. • Tshawb xyuas. • Cov Nyiaj Txiag Nyiaj Txiag. • Daim ntawv cog lus. • Cov ntawv txais nyiaj. • Tub Sab Nraud. • Kev dag ntxias. • Kev cuav. • Kev tua tus kheej. • Kev tua neeg. • Nto nta. • Cov duab latent. • Kev hloov pauv. • Watermarks. • Ink stamps
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
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
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
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
