Cia peb ua piv txwv ntawm ib tsis pub ua los ntawm lub hauv paus tsis muaj zog ammonia , NH3 thiab nws cov conjugate acid, NH4 +. Thaum twg HCl (muaj zog acid) ntxiv rau qhov no tsis pub system, qhov ntxiv H + ions ntxiv rau lub kaw lus tau noj los ntawm cov NH3 rau daim ntawv NH4+. Qhov ntxiv ntawm cov kua qaub los yog lub hauv paus rau lub tsis pub yuav hloov nws cov pH sai.
Ib yam li ntawd, nh3 thiab NH4Cl puas yog cov tshuaj tsis haum?
Teb thiab piav qhia: Ammonia thiab ammonium chloride tsis pub yog ib tug sib tov ntawm qaug zog acid thiab nws cov ntsev. Nws yog ib qho yooj yim tsis pub vim hais tias lub hauv paus dissociation tas li rau ammonia yog ntau dua cov kua qaub tas li rau ammonium ions.
Ib yam li ntawd, hom tshuaj tiv thaiv dab tsi yog HCl thiab nh3? Yog li NH3 thaum tau txais H+ ntawm HCl (H + thiab Cl-) tsim NH4 + (ammonium ion) uas ntawm kev sib raug zoo nrog Cl-ion (los ntawm HCl ) muab NH4Cl (ammonium chloride). Cov tshuaj tiv thaiv yog sawv cev li NH3 + HCl = NH4Cl.
Cov lus nug tseem yog, dab tsi tshwm sim thaum HCl ntxiv rau ammonia tsis?
Cov tshuaj hydrochloric kua qaub yuav hnov mob hnyav nrog ammonia los tsim ammonium chloride (uas yog ib qho acidic ntsev me ntsis, feem ntau tsis muaj teeb meem), neutralizing lub hauv paus ntawm cov tshuaj, thiab muaj zog tsim ntawm hydrogen gas npuas yuav raug soj ntsuam, raws li fizzing ntawm cov tshuaj.
Yuav ua li cas ua ib qho ammonia buffer tov?
Ammonia - Ammonium Chloride Tsis pub : Dissolve 67.5 g ntawm ammonium chloride nyob rau hauv li 200 ml dej, ntxiv 570 ml ntawm muaj zog tshuaj ammonia thiab dilute nrog dej rau 1000 ml. Ammonia Buffer pH 9.5: Dissolve 33.5 g ntawm ammonium chloride hauv ISO ml dej, thiab 42 ml ntawm 10M ammonia thiab dilute nrog dej rau 250 ml.

Puas yog gal4 protein nyob rau hauv cov poov xab ua tau zoo lossis tsis zoo ntawm GAL noob?
Gal4 transcription yam yog ib tug zoo regulator ntawm noob qhia ntawm galactose-induced noob. Cov protein no sawv cev rau tsev neeg loj ntawm cov kab mob ntawm cov kab mob, Gal4 tsev neeg, uas suav nrog ntau dua 50 tus tswv cuab hauv cov poov xab Saccharomyces cerevisiae xws li. Oaf1, Pip2, Pdr1, Pdr3, Leu3
Puas yog tus ntiv tes yog qhov hloov pauv tsis tu ncua lossis tsis txuas ntxiv?
Kev hloov pauv tsis tu ncua yog qhov sib txawv, thiab cov no yog cov yam ntxwv ntawm caj ces hloov, xws li qhov siab, xim plaub hau, khau loj. Koj qhov siab, qhov hnyav, ntiv tes ntev thiab lwm yam, yuav tau hloov pauv hauv koj lub neej (nruam), tab sis koj hom ntshav, hom pob ntseg, ntiv tes thiab poj niam txiv neej, tsis txhob (tsis txuas ntxiv)
Puas yog kub suav tau lossis suav tsis tau?
Piv txwv li, hauv kab lus muab, Kub tsis suav nrog vim nws tsis muaj ntau daim ntawv. Yog li ntawd, nws raug cais nyob rau hauv qeb ntawm uncountable khoom
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Puas yog tearing ntawm daim ntawv yog qhov hloov tsis tau?
Tearing ntawm daim ntawv yog ib qho kev hloov ntawm lub cev vim hais tias thaum daim ntawv torn tsuas yog cov tsos ntawm daim ntawv hloov thiab tsis muaj cov khoom tshiab tsim. Tom qab ntawd daim ntawv yog hloov mus rau hauv tshauv no tshuaj hloov pauv yog irreversible hloov
