Kauj Ruam 4: Lub molecular geometry piav qhia txoj haujlwm nkaus xwb ntawm atomic nuclei (tsis yog ib leeg electron khub) ntawm cov molecule (lossis ion). Yog tsis muaj ib leeg electron khub ntawm lub hauv paus atom, khub electron thiab molecular geometries yog tib yam.
Yuav ua li cas molecular geometry thiab electron geometry zoo ib yam?
Linear geometry suav nrog lub hauv paus atom nrog ob khub ntawm kev sib txuas ntawm electrons ntawm lub kaum sab xis ntawm 180 degrees (ib txoj kab ncaj nraim). Qhov no tsuas yog qhov ua tau zoo rau ib kab geometry; cov electron geometry thiab molecular geometry yog tib yam.
Puas yog cov qauv molecular thiab molecular geometry tib yam?
Molecular geometry, tseem hu ua cov qauv molecular, yog tus qauv peb-dimensional lossis kev npaj ntawm atoms hauv ib lub molecule. Kev nkag siab txog cov qauv molecular ntawm cov khoom sib xyaw tuaj yeem pab txiav txim siab polarity, reactivity, theem ntawm cov teeb meem, xim, hlau nplaum, nrog rau kev ua haujlwm lom neeg.
Raws li qhov xwm txheej twg yog cov npe ntawm cov electron khub geometry thiab cov qauv molecular tib yam?
Cov electron-pair geometries yuav zoo ib yam li cov qauv molecular thaum tsis muaj ib leeg electron khub nyob ib ncig ntawm lub hauv paus atom, tab sis lawv yuav txawv thaum muaj ib khub nthuav tawm ntawm lub hauv paus atom.
Vim li cas electron geometry txawv ntawm moleculargeometry?
Electron geometry qhia peb txog kev teeb tsa ntawm pawg electron sib txawv. Molecular geometry, ntawm qhov tod tes, pab peb nkag siab tag nrho atom thiab nws txoj kev npaj. Nws yog 3D kev npaj ntawm tag nrho cov atoms nyob rau hauv ib tug tshwj xeeb molecule.

Puas yog cov tib neeg ntawm ib hom niaj hnub no txawv dua li cov tib neeg ntawm tib hom?
Puas yog cov tib neeg ntawm ib hom niaj hnub no zoo li txawv dua li cov tib neeg ntawm tib hom tau ntau tiam dhau los? … Yog, txhua tus neeg tuaj yeem hloov pauv me ntsis thiab dhau qhov kev hloov pauv rau lawv cov xeeb ntxwv. Puas muaj qhov sib txawv ntawm cov tib neeg ntawm tib hom?
Thaum ib yam khoom uas tsis yog tib neeg muab rau tib neeg tus yam ntxwv?
Personification yog qhov tshwm sim ntawm tib neeg cov yam ntxwv, yam ntxwv, lossis kev coj tus cwj pwm rau cov tsis yog tib neeg, yog tsiaj txhu, yam tsis muaj sia, lossis txawm tias cov ntsiab lus tsis muaj tseeb. Qhov twg hauv qab no muab tib neeg yam ntxwv rau yam tsis yog tib neeg?
Ntawm cov kab mob cuam tshuam nrog cov qauv molecular?
Pathogen txuam nrog cov qauv molecular (PAMP) yog molecules nrog kev txuag motifs uas cuam tshuam nrog cov kab mob kab mobuas ua haujlwm li ligands rau tus tswv qauv kev paub txog molecules xws li Kev Hu Xov Tooj Zoo li receptors. Qhov twg ntawm cov no yog cov piv txwv ntawm cov kab mob cuam tshuam nrog cov qauv molecular?
Dab tsi yog aniline xiav stained qauv hauv cov qauv nws yog ib qho hnyav?
Dab tsi yog aniline xiav-stained qauv hauv cov qauv? Nws yogstringy pawg hauv qab plab hnyuv epithelium uas txuas mus rau hauv lub villi. "Aniline xiav khi rau cov txheej txheem extracellular xws li cov fibers hauv lamina propria. Lamina propria yog lub npe ntawm cov ntaub so ntswg sib txuas hauv qab plab hnyuv epithelium.
Thaum lub sijhawm tsom xam ntawm tus qauv addie tus tsim qauv?
Tus qauv ADDIE yog cov txheej txheem dav dav uas ib txwm siv los ntawm cov kws tsim qauv qhia thiab cov neeg tsim kev cob qhia. Tsib theem- Kev tshuaj xyuas, Tsim, Kev Txhim Kho, Kev Ua Haujlwm, thiab Kev Ntsuam Xyuas - sawv cev rau cov lus qhia zoo, hloov tau yooj yim rau kev tsim cov kev cob qhia zoo thiab cov cuab yeej txhawb nqa kev ua tau zoo.
