Kev tawg ntawm decane
Qee qhov me me hydrocarbons tsim los ntawm tawg yog siv los ua roj (xws li cov saw loj feem ntau tawg tsim octane rau roj av, uas yog nyob rau hauv siab thov), thiab cov alkenes yog siv los ua polymers nyob rau hauv kev tsim cov yas. Qee zaum, hydrogen kuj tsim thaum lub sijhawm tawg.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi tuaj yeem decane tawg rau hauv?
Kev tawg ntawm hydrocarbons muaj thermal decomposition. nrog ib tug yooj yim nto rau lub tawg coj qhov chaw. Piv txwv li, decane (ib qho alkane nrog 10 carbons) ua tau ua tawg los tsim octane thiab ethene.
Ib yam li ntawd, hom tshuaj tiv thaiv yog tawg? Kub tawg yog a hom ntawm chemical tshuaj tiv thaiv uas siv cov cua sov los rhuav tshem cov saw ntev molecules rau hauv me me, ntau reactive, thiab yog li ntawd muaj txiaj ntsig zoo dua, molecules. Hauv tsev kawm ntawv chav kuaj, tej zaum koj tau ua tiav tawg rau koj tus kheej siv cov kua paraffin thiab lub lauj kaub tawg.
Ib yam li ntawd, tib neeg nug, alkenes puas tuaj yeem tawg?
Kev tawg thiab alkenes . Kev tawg yog ib qho tshuaj tiv thaiv uas loj saturated hydrocarbon molecules tau tawg mus rau hauv me me, muaj txiaj ntsig zoo hydrocarbon molecules, qee qhov tsis txaus: cov khoom ntawm tawg suav nrog alkanes thiab alkenes , cov tswv cuab ntawm homologous sib txawv.
Yuav ua li cas thaum tawg?
Hauv Petrochemistry, roj av geology thiab organic chemistry, tawg yog cov txheej txheem uas nyuaj cov organic molecules xws li kerogens los yog cov saw hlau ntev hydrocarbons tau tawg mus rau hauv yooj yim molecules xws li lub teeb hydrocarbons, los ntawm kev tawg ntawm carbon-carbon bonds. hauv cov precursors.
Pom zoo:
Puas yog Dolomite muaj kev tawg lossis tawg?
Dolomite tsis tshua pom muaj nyob rau hauv ib puag ncig niaj hnub sedimentary, tab sis dolostones muaj ntau heev hauv cov ntaub ntawv pob zeb. Lub cev muaj zog ntawm Dolomite Chemical Classification Carbonate Diaphaneity Transparent to translucent Cleavage Perfect, rhombohedral, peb cov lus qhia Mohs Hardness 3.5 txog 4
Yuav ua li cas zoo li Yellowstone yuav tawg?
'Ua Sijhawm dhau mus' tuaj yeem siv rau cov phau ntawv hauv tsev qiv ntawv, daim nqi, thiab kev hloov roj, tab sis nws tsis siv rau Yellowstone! Hais txog kev tawg loj, Yellowstone tau ntsib peb - ntawm 2.08, 1.3, thiab 0.631 lab xyoo dhau los. Qhov no tawm mus rau qhov nruab nrab ntawm 725,000 xyoo ntawm kev tawg
Puas yog supernova tawg tawg?
Ib tug supernova (/ˌsuːp?rˈno?v?/ plural: supernovae /ˌsuːp?rˈno?viː/ los yog supernovas, cov ntawv luv: SN thiab SNe) yog qhov muaj zog thiab lub hnub qub tawg tawg. Qhov kev tshwm sim astronomical no tshwm sim thaum lub sij hawm kawg evolutionary theem ntawm lub hnub qub loj heev los yog thaum ib tug dawb dwarf tau tshwm sim rau hauv khiav tawm nuclear fusion
Yuav ua li cas thaum lub hnub qub loj tawg?
Muaj teeb meem ntau dhau ua rau lub hnub qub tawg, ua rau lub supernova. Raws li lub hnub qub khiav tawm ntawm cov roj nuclear, qee qhov ntawm nws cov huab cua ntws mus rau hauv nws cov tub ntxhais. Thaum kawg, lub hauv paus tseem hnyav heev uas nws tsis tuaj yeem tiv taus nws tus kheej lub zog gravitational. Cov tub ntxhais hluas tawg, uas ua rau muaj qhov tawg loj heev ntawm supernova
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
