thaum MGCL2 yog electrolysed Tom qab ntawd MG2 + ion tso rau ntawm anode thiab 2CL-ion tso rau ntawm cathode. Lub 2CL-ion poob nws 2 electron thiab dhau los ua CL2 (gas). yog li ntawd rau electrolysis ntawm MGCL 2 peb tau txais MG thiab CL2 (gas).
Tsis tas li ntawd, yuav ua li cas thaum magnesium chloride Electrolysed?
Lwm qhov tseem ceeb ntawm kev siv electrolysis yog nyob rau hauv zus tau tej cov magnesium los ntawm dej hiav txwv. Cov magnesium chloride Tom qab ntawd melted thiab electrolyzed. Zoo ib yam li kev tsim cov sodium los ntawm molten sodium tshuaj chloride , saum toj no, lub molten magnesium yog tso rau ntawm cathode, thaum cov roj chlorine tso tawm ntawm lub anode.
Qhov thib ob, vim li cas ho tsis yog cov tshuaj aqueous ntawm MgCl2 siv hauv electrolysis? Magnesium tau txais los ntawm electrolysis ntawm molten MgCl2. (A) Aqueous daws ntawm tsis yog siv hauv electrolysis txheej txheem vim hais tias tus qauv txo qhov peev xwm ntawm ntau dua li ntawm li qhov tshwj xeeb yog txo thiab tsis txo yog li tsis tau.
Raws li txoj cai, yuav ua li cas thaum molten magnesium chloride Electrolysed?
MgCl 2 yuav tsum tau cua sov kom txog thaum molten kom nws ua hluav taws xob. Thaum twg molten Koj muaj Mg2+ thiab 2Cl-ions. Ces electrolysis cais cov ntsiab lus. Mg2 + txo qis ntawm cathode (-) thiab Cl- yog oxidized ntawm anode (+).
Vim li cas magnesium ions mg2 +) txav mus rau qhov tsis zoo electrode?
Cov tsis zoo raug them electrode hauv electrolysis yog npe cathode. Kev them nqi zoo ions txav mus rau cathode. Tsis zoo raug them ions txav mus rau lub anode.

Dab tsi yog tsim thaum potassium nitrate Electrolysed?
Electrolysis ntawm cov tshuaj potassium nitrate tsim cov pa oxygen ntawm anode thiab hydrogen ntawm cathode
Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
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
