Cycloalkenes muaj cov cov mis loj C H2(n-m). Tsab ntawv m sawv cev rau tus lej ntawm ob daim ntawv cog lus. Yog li, cyclopropene muaj cov khoom siv qauv C3H4 Thaum cov cyclobutene yog C4H6. Cov khoom ntawm alkanes thiab alkenes zoo sib xws.
Ib yam li ntawd, tib neeg nug, dab tsi yog cov qauv ntawm Cycloalkanes?
cycloalkanes : Cyclic saturated hydrocarbons nrog a cov mis loj ntawm CnH(2n). Cycloalkanes yog alkanes nrog carbon atoms txuas rau hauv daim ntawv ntawm lub nplhaib kaw.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov qauv ntawm cov saw ncaj alkene nrog ib qho C C)? Alkenes yog unsaturated hydrocarbons uas muaj yam tsawg kawg nkaus ib C = C daim ntawv cog lus. Lawv muaj general formula C H2 ib n, thiab muaj npe zoo ib yam li alkanes (saib Tshooj 10.1.
Kuj nug, vim li cas cov qauv dav dav rau Cycloalkanes?
4.5 Cycloalkanes Cov cov mis loj rau alkane yog C H2 ib n+2. Txhua lub nplhaib nyob rau hauv ib qho chaw txo cov naj npawb ntawm hydrogen atoms los ntawm 2 txheeb ze rau ib qho alkane vim hais tias lub nplhaib muaj cov pa roj carbon ntxiv-carbon thiab, yog li ntawd, ob tsawg dua carbon-hydrogen bonds.
Dab tsi Cycloalkane ruaj khov tshaj?
Cyclopentane yog ib ruaj khov molecule nrog ib tug me me ntawm lub nplhaib strain, thaum cyclohexane muaj peev xwm txais yuav lub zoo meej geometry ntawm ib tug cycloalkane nyob rau hauv uas tag nrho cov ces kaum yog qhov zoo tagnrho 109.5 ° thiab tsis muaj hydrogen eclipsed; nws tsis muaj ring strain kiag li. Yog li ntawd nws lub feem ntau ruaj khov cycloalkane.

Yuav ua li cas koj hloov daim ntawv dav dav mus rau cov qauv ntawm hyperbola?
Tus qauv qauv ntawm ib tug hyperbola uas openssideways yog (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1. Rau lub hyperbola uas qhib thiab nqis, nws yog (y - k) ^2 / a^2 - (x- h)^2 / b^2 = 1. Nyob rau hauv ob qho tib si, qhov chaw ntawm lub hyperbolais muab los ntawm (h, k)
Lub ntsiab lus dav dav rau RuBisCO yog dab tsi?
Ribulose-1,5-bisphosphate carboxylase/oxygenase, feem ntau paub los ntawm cov ntawv luv luv Rubisco, rubisco, RuBPCase, lossis RuBPco, yog ib qho enzyme koom nrog thawj kauj ruam tseem ceeb ntawm kev kho cov pa roj carbon monoxide, txheej txheem uas cov pa roj carbon dioxide hloov los ntawm cov nroj tsuag thiab lwm yam. Cov kab mob photosynthetic muaj zog nplua nuj
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
