Borane, ib qho ntawm homologous series ntawm inorganiccompounds ntawm boron thiab hydrogen los yog lawv derivatives. Cov qauv ntawm peb-centre, ob-electron daim ntawv cog lus nyob rau hauv ib tug B-H-Bfragment ntawm ib tug diborane molecule. Ib khub ntawm electrons nyob rau hauv bondingcombination rub tag nrho peb atoms ua ke.
Yog li ntawd, dab tsi yog borane hauv chemistry?
Boranes yog lub npe muab rau cov chav kawm ntawm hluavtaws hydrides ntawm boron nrog generic formulaBxHy. Yav tag los, borane molecules feem ntau tau sau tias "electron-deficient" vim lawv qhov chaw sib txuas (uas yog ib khub ntawm kev sib txuas ntawm electrons ntau dua ob lub atoms, xws li hauv 3-center-2-electron bonds); qhov no tau ua tiav hauv
Ib yam li ntawd, puas yog bh3 soluble hauv dej? Nws muaj cov tshuaj formula ntawm NH3 BH 3 . Nws kuj yog soluble hauv ether thiab dej thaum tsis kho.
Kuj nug, bh3 hu li cas?
Niam txiv molecule ntawm no series ( BH3 ) kuj npe borane . Borane . Methyl borane . Ib qho organoborane.
Muaj pes tsawg hom Boranes muaj?
Daim vis dis aus no qhia txog dab tsi yog closeo, nido thiab archano cov boranes .dab tsi yog peb qhov chaw ob daim ntawv cog lus electron. muaj pes tsawg hom ntawm daim ntawv cog lus yog tam sim no nyob rau hauv boranes thiab stvxcode los yog styx tooj yog dab tsi.

Dab tsi ua rau cov kab hauv emission spectrum rau cov ntsiab lus?
Cov kab hluav taws xob tshwm sim thaum cov hluav taws xob ntawm cov atom zoo siab, cov khoom lossis cov molecule txav ntawm qib zog, rov qab mus rau hauv av. Cov kab spectral ntawm ib lub caij tshwj xeeb lossis molecule ntawm so hauv chav kuaj ib txwm tshwm sim ntawm tib lub wavelengths
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
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
