Yuav ua li cas koj yuav tsum siv ib tug flowchart rau npe ib tug tshuaj compound ? Rau npe a compound los yog sau nws cov qauv, ua raws li cov cov kab kos hauv cov duab 9.20 thiab 9.22 kom raug npe los yog formula.
Yog li ntawd, ua li cas koj thiaj li hu ua chemical compound flowchart?
- H. (Compound yog ib qho acid.
- Siv lub npe ntawm anion. Yog hais tias lub anion xaus rau hauv "-ate," noj.
- -2 (sulfate) ua.
- "sulfuric." Yog hais tias lub anion xaus rau hauv "-ite", coj.
- -2 (sulfite) ua.
- "sulfurous." Ntxiv lo lus "acid" mus rau qhov kawg ntawm lub hauv paus koj nyuam qhuav ua.
Ib tug kuj yuav nug, dab tsi yog txoj cai rau naming binary compounds? Cov cai rau Naming Binary Ionic Compounds
- Lub npe tag nrho ntawm cation yog teev ua ntej.
- Lub hauv paus ntawm lub npe anion yog teev thib ob thiab ua raws li cov lus "ide."
- Yog tias qhov sib xyaw muaj cov hlau hloov pauv, tus lej Roman suav nrog tom qab lub npe hlau los qhia tus lej oxidation ntawm cov hlau.
Tsis tas li ntawd, qhov twg yog qhov tseeb rau cov npe thiab cov qauv ntawm binary ionic compounds?
Rau ib binary ionic compound , hlau yuav ib txwm yog thawj lub hauv paus qauv , thaum lub nonmetal yuav ib txwm yog qhov thib ob. Cov hlau cation yog lub npe ua ntej, ua raws li cov nonmetal anion. Subscripts nyob rau hauv qauv tsis cuam tshuam rau npe.
Cov piv txwv ntawm polyatomic ions yog dab tsi?
Tseeb tiag, feem ntau ionic cov tshuaj muaj polyatomic ions . Paub zoo piv txwv yog sodium hydroxide (NaOH) nrog OH- raws li cov polyatomic anion, calcium carbonate (CaCO3), thiab ammonium nitrate (NH4TSIS MUAJ3), uas muaj ob polyatomic ions : NH+ thiab NO3-.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Yuav ua li cas koj nthuav qhia cov txheeb cais nyob rau hauv ib daim ntawv qhia?
Cov txiaj ntsig piav qhia suav nrog ib lub rooj nrog cov ntaub ntawv txheeb xyuas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv. Cov ntaub ntawv piav qhia yuav tsum muaj feem xyuam rau lub hom phiaj ntawm kev kawm; nws yuav tsum tsis txhob suav nrog rau lub hom phiaj ntawm nws. Yog tias koj tsis mus siv hom nyob qhov twg, tsis txhob suav nrog nws
Koj piav qhia txog daim ntawv qhia topographic li cas?
Daim duab qhia chaw saum toj saud feem ntau yog daim ntawv qhia loj loj uas piav qhia txog lub cev thiab tus txiv neej tsim ntawm toj roob hauv pes; thiab muaj qhov txawv txav los ntawm qhov pom ntawm cov kab contour uas qhia txog kev nthuav dav hauv av nyem ntawm thaj av
Daim duab qhia lub cev dawb qhia koj li cas txog lub zog net ntawm ib qho khoom?
Daim duab dawb-lub cev qhia cov vectors rau txhua lub zog ua haujlwm ntawm lub cev. Qhov tshwm sim vector pom los ntawm kev suav tag nrho tus kheej vectors sawv cev rau lub zog nqa. Txij li thaum F = ma, lub acceleration vector yuav taw tes rau hauv tib txoj kev raws li lub zog net, nrog rau qhov loj ntawm F / m
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
