Cov hydrogen ces muaj ib nrab nqi zoo. Kom paub txog qhov ua tau hydrogen bonding , tshuaj xyuas cov qauv ntawm Lewis molecule . Lub atom electronegative yuav tsum muaj ib lossis ntau dua cov khoom siv hluav taws xob tsis sib xws xws li cov pa oxygen thiab nitrogen, thiab muaj cov nqi tsis zoo.
Dhau li ntawm no, cov molecule twg muaj hydrogen bonding?
dej
Tsis tas li ntawd, yog dej polar lossis nonpolar? Dej (H2O) yog polar vim qhov khoov zoo ntawm cov molecule. Cov duab txhais tau hais tias feem ntau ntawm cov nqi tsis zoo los ntawm cov pa oxygen ntawm sab ntawm lub molecule thiab cov nqi zoo ntawm hydrogen atoms nyob rau sab nraud ntawm lub molecule. Qhov no yog ib qho piv txwv ntawm polar covalent chemical bonding.
Qhov thib ob, lub zog ntawm hydrogen bonds txiav txim siab li cas?
1 Hydrogen bonding . Hydrogen bonds yog tsim los ntawm ib tug electronegative atom thiab a hydrogen atom bonded rau lub thib ob electronegative atom [80]. Cov zog ntawm hydrogen daim ntawv cog lus nyob ntawm qhov electronegativity ntawm cov atoms; Table 1 faib hydrogen bonds muaj zog heev (piv txwv li, [F…H… F]−), muaj zog (e.g., O H…
Vim li cas hydrogen bonds tseem ceeb?
Hydrogen bonding yog tseem ceeb hauv ntau cov txheej txheem tshuaj. Hydrogen bonding yog lub luag hauj lwm rau dej cov kuab tshuaj tshwj xeeb muaj peev xwm. Hydrogen bonds tuav cov kab sib txuas ntxiv ntawm DNA ua ke, thiab lawv yog lub luag haujlwm rau kev txiav txim siab peb-dimensional qauv ntawm folded proteins nrog rau cov enzymes thiab cov tshuaj tiv thaiv.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Yuav ua li cas koj thiaj paub yog hais tias ib tug scatter plot tsis muaj zog los yog muaj zog?
Peb hais tias muaj kev sib raug zoo tsis zoo nyob nruab nrab ntawm qhov sib txawv x thiab y. Xav txog cov nram qab no scatterplot: Peb saib tias y nce li x nce, thiab cov ntsiab lus tsis nyob ntawm txoj kab ncaj nraim. Peb hais tias ib qho kev sib raug zoo tsis muaj zog muaj nyob nruab nrab ntawm qhov sib txawv x thiab y
Yuav ua li cas koj qhia yog hais tias ib tug piecewise graph yog ib tug muaj nuj nqi?
Yuav Qhia Li Cas Yog Piecewise Function yog Nruam lossis Tsis Txuas Ntxiv. Txhawm rau qhia yog tias daim duab sib txuas tsis tu ncua lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom tias y point yog tib yam ntawm lawv txhua tus.(Yog tias y's txawv, yuav muaj "dhia" hauv daim duab !)
