Cov pa roj carbon atom nruab nrab rau lub methane molecule muaj 4 valence electrons thiab yog li xav tau 4 ntau electrons los ntawm plaub hydrogen atoms kom tiav nws octet. Cov hydrogen atoms muaj 109 degree daim ntawv cog lus lub kaum sab xis muab lub molecule ib tetrahedral geometry.
Ib yam li ntawd, nws raug nug, hom qauv twg muaj methane?
Methane yog ib tug compound uas muaj ob yam, carbon thiab hydrogen. Nws tshwm sim raws li ib tug molecule. Txhua methane molecule muaj lub hauv paus carbon atom koom nrog thiab ncig los ntawm plaub hydrogen atoms.
Tom qab ntawd, lo lus nug yog, qhov zoo li cas ntawm methane? Cov zoo li methane Qhov ntawd yog tetrahedral kev npaj, nrog lub kaum sab xis ntawm 109.5 °. Tsis muaj dab tsi hloov nyob rau hauv cov nqe lus ntawm lub puab Thaum cov hydrogen atoms ua ke nrog cov carbon, thiab yog li ntawd methane molecule kuj yog tetrahedral nrog 109.5 ° daim ntawv cog lus kaum.
Yog li ntawd, dab tsi muaj methane?
Methane , CH4, yog cov roj tsis muaj xim, tsis muaj ntxhiab tsw, nrog rau qhov dav dav hauv qhov xwm txheej. Nws yog lub hauv paus tseem ceeb ntawm cov pa roj, sib tov muaj 75% CH4, 15% ethane (C2H6), thiab 5% lwm cov hydrocarbons, xws li propane (C3H8) thiab butane (C4H10). Qhov "firedamp" ntawm thee mines yog qhov tseem ceeb methane.
Tib neeg puas tsim methane?
Raws li rau methane (CH4), feem ntau tib neeg ua tsis tau tsim tawm nws tag nrho. Methane nyob rau hauv lub cev tshwm sim los ntawm microbes hu ua methanogens, uas tsis yog cov kab mob tab sis cov tswv cuab ntawm Archaea lub nceeg vaj, lub neej qub tshaj plaws nyob rau hauv lub ntiaj teb no. Tsuas yog ib feem peb ntawm tib neeg muaj methanogens ntawm lawv cov plab hnyuv.

Leej twg yog tus qauv ntawm ib qho tsis muaj polar molecule uas muaj cov ntawv cog lus nonpolar?
(1), (3) H2O thiab NH3 yog cov molecules uas muaj polar covalent bonds, tab sis lawv cov khoom siv hluav taws xob tsis sib luag. (4) H2 yog ib tug nonpolar molecule uas muaj ib tug symmetrical tis ntawm electrons, tab sis cov nyiaj ntawm cov hydrogen atoms yog nonpolar covalent
Cov qauv ntawm cov pa roj carbon zoo li cas rau ntau yam ntawm macromolecules pom hauv cov khoom muaj sia?
Cov pa roj carbon atom muaj cov khoom tshwj xeeb uas tso cai rau nws los tsim cov ntawv cog lus rau ntau li plaub lub atoms sib txawv, ua kom muaj ntau yam khoom zoo tagnrho los ua tus qauv tsim qauv, lossis "ncaj qaum," ntawm macromolecules
Cov qauv twg muaj nyob hauv cov hlwb prokaryotic?
Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Cov cell prokaryotic tsis muaj cov nucleus thiab cov txheej txheem sib khi
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
Qhov twg ntawm cov qauv no muaj cov enzymes digestive?
Lysosomes: Lysosomes yog cov kab mob sib txuas uas muaj cov kab mob digestive uas zom cov protein, lipids, carbohydrates, thiab nucleic acids. Lawv yog ib qho tseem ceeb hauv kev ua cov ntsiab lus ntawm vesicles coj los ntawm sab nraum lub cell
