Cov qauv ntawm yog raws li hauv qab no: Ntawm no muaj 3 H atoms txuas rau 3 O atoms. Cov atoms no hloov mus rau hauv ions los ntawm pub 1 electron rau Oxygen li Oxygen muaj ntau electronegativity dua hydrogen. Yog li no triprotic vim nws tuaj yeem tso 3 ions.
Tsis tas li ntawd, yog h3po4 yog Triprotic acid?
Phosphoric Acid , H3PO 4 (aq) yog a triprotic acid , txhais tau tias ib tug molecule ntawm lub kua qaub muaj peb acidic protons. Kwv yees cov pH thiab cov concentrations (M) ntawm txhua hom hauv 0.450 M phosphoricacid daws.
Qhov thib ob, yog h3po3 Triprotic? Phosphorous acid, yog qhov sib xyaw uas tau piav qhia los ntawm theformula H3PO3. Cov kua qaub no yog diprotic (readilyionizes ob protons), tsis yog triprotic raws li tej zaum yuav tau hais los ntawm cov qauv no. Phosphorous acid yog qhov nruab nrab hauv kev npaj ntawm lwm cov phosphorus compounds.
Ib yam li ntawd, puas yog phosphoric acid Triprotic?
Raws li lawv lub npe qhia, polyprotic tshuaj acids muaj ntau tshaj ib tug acidic proton. Ob qho piv txwv yog carbonic kua qaub (H2CO3, uas muaj ob acidic protons thiab yog li adiprotic kua qaub ) thiab phosphoric acid (H3PO4, uas hasthree acidic protons thiab yog li ntawd a triproticacid ).
Vim li cas phosphoric acid yog Triprotic acid?
Qhov tseem ceeb tshaj plaws polyprotic acid pab pawg los ntawm abiological standpoint yog triprotic phosphoric acid . Vim phosphoric acid muaj peb acidic protons, nws kuj muaj peb pKib tus nqi. H3PO4 yog muaj zog kua qaub vim hais tias tus (ib zaug) tsis zoo nqi ntawm nws conjugate puag H2PO4- tuaj yeem bedelocalized tshaj ob lub atoms oxygen.

Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Qhov twg yog qhov zoo dua qhov kev xaiv ntuj los yog kev xaiv dag Yog vim li cas?
Thaum lub sij hawm xaiv ntuj, hom ciaj sia thiab kev yug me nyuam txiav txim siab cov yam ntxwv. Txawm hais tias tib neeg tuaj yeem txhim kho lossis ua rau lub cev muaj peev xwm los ntawm kev xaiv kev yug me nyuam, qhov xwm txheej cuam tshuam nws tus kheej nrog cov yam ntxwv uas tso cai rau qhov zoo rau cov tsiaj muaj peev xwm ua phooj ywg thiab muaj sia nyob
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
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
