Dab tsi yog qhov zoo o2 ? | kab tawm |

Yog li ntawd, lub cev molecular ntawm oxygen yog dab tsi?
Siv cov ntaub ntawv no thiab Table 3.1 peb pom tias cov molecular zoo yog tetrahedral. Central atom yog oxygen (koj tuaj yeem pom qhov no los ntawm kev kos duab molecules Lewis daim duab). Muaj ob lub tshuab hluav taws xob nyob ib puag ncig oxygen thiab ob leeg ib leeg. Cov molecule muaj cov qauv dav dav (ext{AX}_{2} ext{E}_{2}).
Ib sab saum toj, vim li cas o2 trigonal planar? O atom yog sp2 hybridized thiab nws cov qauv yog trigonal txoj kev . Yog li, ib qho O atom muaj ib daim ntawv cog lus (doube daim ntawv cog lus) thiab ob lub lonepairs. Txij li thaum peb xav txog cov duab peb tsis suav nrog cov khub ib leeg, tsuas yog ib qho kev sib cog lus ua rau nws cov duab linear. Tab sis nws tus qauv los yog geometry yog trigonal txoj kev.
Ib yam li ntawd, tib neeg nug, yog o2 linear lossis khoov?
Cov oxygen muaj 6 valence electrons thiab yog li xav tau 2 ntau electrons los ntawm 2 hydrogen atoms kom tiav nws octet. Lub molecule yog ob sab thiab khoov as opposed to beryllium hydride case uas yog a kab tawm los yog txoj kab ncaj nraim molecular geometry vim nws tsis muaj ib leeg electron khub.
Lub kaum sab xis ntawm o2 yog dab tsi?
Lub trioxygen molecule O3 muaj ib tug ib leeg thiab ua ib tug khoov duab nrog daim ntawv cog lus cov ces kaum ntawm 118 degrees. Ntawm qhov tod tes, O2 muaj ob leeg ib khub thiab ib tug linear duab.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Lub cev molecular ntawm cov molecule hauv qab no yog dab tsi?
Yog hais tias cov no yog tag nrho cov kev sib raug zoo ua ke lub molecular geometry yog tetrahedral (xws li CH4). Yog hais tias muaj ib leeg ib khub ntawm electrons thiab peb daim ntawv cog lus cov txiaj ntsig molecular geometry yog trigonal pyramidal (xws li NH3). Yog hais tias muaj ob daim ntawv cog lus thiab ob leeg ib leeg ntawm electrons lub molecular geometry yog angular los yog khoov (xws li H2O)
Lub luag haujlwm ntawm lub cev thiab lub cev yog dab tsi?
Anatomy yog kev kawm txog cov qauv thiab kev sib raug zoo ntawm lub cev. Physiology yog kev kawm txog kev ua haujlwm ntawm lub cev thiab lub cev tag nrho
