Cia li nco ntsoov, hauv ib tawg sib npaug , cov reactant yog alkane ntev thiab ob yam khoom yog me me alkane thiab alkene molecules. Los ntawm kev siv tus general qauv , nws yog ua tau kom sib npaug ntawm tawg sib npaug . Alkane yog CnH2n + 2 thiab Alkene yog CnH2n.
Ces, 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 yuav tau ua tawg rau koj tus kheej siv cov kua paraffin thiab lub lauj kaub tawg.
Ib yam li ntawd, ob hom kev tawg yog dab tsi? Hom Cracking - Cua sov Kev tawg thiab Catalytic Kev tawg . Kev tawg yog ib tug txheej txheem uas complex high molecular hnyav cov organic tebchaw yog tawg mus rau hauv me me fragments ntawm molecules. Lub complex siab molecular hnyav organic tebchaw yog feem ntau ntev chained hydrocarbons xws li roj av.
Ntawm no, dab tsi yog txheej txheem ntawm cracking?
Hauv petrochemistry, roj av geology thiab organic chemistry, tawg yog cov txheej txheem Qhov no complex organic molecules xws li kerogens los yog ntev-chain hydrocarbons tau tawg mus rau hauv yooj yim molecules xws li lub teeb hydrocarbons, los ntawm kev tawg ntawm carbon-carbon bonds nyob rau hauv lub precursors.
Yuav ua li cas tawg ua GCSE?
Kev tawg tso cai rau loj hydrocarbon molecules kom tawg mus rau hauv me me, muaj txiaj ntsig zoo hydrocarbon molecules. Cov feem uas muaj cov loj hydrocarbon molecules yog rhuab kom vaporize lawv. Tom qab ntawd lawv yog: rhaub rau 600-700 ° C.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
