Nws yog siv rau txiav txim siab cov khoom ntawm ib qho kev hloov pauv hloov, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv qhov series . Kev ua yeeb yam series ntawm ib co ntawm ntau hom hlau, teev nyob rau hauv descending kev txiav txim ntawm reactivity.
Ib yam li ntawd, qhov kev ua yeeb yam yog dab tsi thiab nws ua haujlwm li cas?
Cov kev ua haujlwm ntawm cov hlau yog ib qho cuab yeej siv los kwv yees cov khoom hauv hloov chaw cov tshuaj tiv thaiv thiab reactivity ntawm hlau nrog dej thiab acids nyob rau hauv kev hloov cov tshuaj tiv thaiv thiab ore extraction. Nws tuaj yeem siv los kwv yees cov khoom lag luam zoo sib xws nrog cov hlau sib txawv.
Tsis tas li ntawd, vim li cas cov kev ua haujlwm series ua haujlwm? Kev Ua Haujlwm Series . Lub peev xwm ntawm ib lub ntsiab lus teb nrog lwm lub ntsiab lus yog npe nws kev ua si . Qhov yooj yim dua yog rau ib lub ntsiab lus teb nrog lwm cov khoom, qhov ntau dua nws kev ua si . Rau cov hlau, qhov loj dua kev ua si , qhov yooj yim dua lawv poob electrons, tsim cov ions zoo.
Tsis tas li ntawd, cov hlau reactivity series ua haujlwm li cas?
Cov hlau reactivity series cov npe hlau nyob rau hauv kev txiav txim ntawm lawv reactivity , los ntawm siab tshaj mus rau qis tshaj los ntawm sab saum toj mus rau hauv qab. A hlau teev saum toj no lwm tus hlau yuav hloov qhov ntawd hlau nyob rau hauv ib qho kev hloov pauv (ib qho kev hloov pauv) cov tshuaj tiv thaiv.
Dab tsi yog kev ua yeeb yam series Nws pab peb li cas hauv kev kwv yees?
Ib tug hlau muab tso rau saum hydrogen nyob rau hauv lub kev ua yeeb yam series yuav tshem tawm hydrogen los ntawm dej los yog acids. Ib tug hlau muab tso rau saum lub kev ua yeeb yam series tshem cov hlau hauv qab nws. Yog li, ib qho hlau reactive dua displaces ib tug tsawg reactive hlau los ntawm nws cov ntsev tov.

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 koj paub thaum twg yuav siv brackets los yog parentheses interval notation?
Nws yog ib hom kev sau ntawv uas sawv cev rau qhov nruab nrab nrog ib khub ntawm tus lej. Cov kab lus thiab cov brackets yog siv los qhia seb puas yog ib qho ntsiab lus tsis suav nrog. Ib qho kev sib dhos yog siv thaum lub ntsiab lus lossis qhov muaj nuj nqis tsis suav nrog hauv lub sijhawm, thiab siv lub bracket thaum tus nqi suav nrog
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
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
