NH4 + muaj tus nqi + vim nws yog NH3 uas tau tsim nrog H + siv N ib khub. Tag nrho cov ion muaj 1 ntau proton tshaj nws muaj electrons li no tus nqi.
Kuj tseem paub yog, vim li cas ammonium zoo?
Cov zoo them H + ion, los yog proton, isattracted rau ib leeg khub ntawm qhov tsis zoo kawg ntawm lub ammonia dipole. Qhov txawv tab sis qhov tseem ceeb yog qhov ammonium ion muaj ib tug ntxiv proton nyob rau hauv lub nucleus ntawm lub nruab nrab atom thiab li no tag nrho cov nqi ntawm +1.
Tsis tas li ntawd, puas yog ammonia zoo lossis tsis zoo? Ammonia yog ib tug polar molecule: Saib daim duab ntawm sab laug. Lub trigonal pyramid geometry nrog ib leeg electron khub pab txhawb rau cov nyhuv. Theelectrostatic muaj peev xwm qhia tau meej tias cov nitrogen yog ib feem tsis zoo hos cov hydrogens yog ib feem zoo.
Tom qab ntawd, vim li cas nh4 yog ion?
Ammonium ions , NH4+ , yog tsim los ntawm kev hloov ntawm hydrogen ion los ntawm hydrogen chloride mus rau thelone khub ntawm electrons ntawm ammonia molecule. Cov hydrogen'selectron tau tso tseg ntawm cov tshuaj chlorine los tsim cov tshuaj tsis zoo chloride ion.
Puas yog nh4+ yog acid lossis base?
Yog li, NH3 yog a puag thiab H2O yog ib qho kua qaub . Ib kua qaub – puag Cov tshuaj tiv thaiv yog suav tias yog ib qho kev hloov pauv proton (H +) cov tshuaj tiv thaiv. - Hom NH4 + thiab NH3 yog aconjugate kua qaub - puag khub.

Vim li cas kev sib raug zoo tsis zoo?
Tsawg cohesion tsis zoo vim nws qhia tias muaj cov ntsiab lus hauv chav kawm uas tsis tshua muaj kev sib koom ua ke. Modules uas nws cov ntsiab lus muaj zog thiab muaj kev sib raug zoo tiag tiag yog xav tau. Txhua txoj kev yuav tsum tau cohesive heev. Feem ntau txoj kev tsuas muaj ib txoj haujlwm los ua
Vim li cas cov lej ntawm ob tus lej zoo ib txwm zoo?
Qhov sum yog cov lus teb rau ib qho teeb meem ntxiv.Qhov sum ntawm ob qhov zoo integers yeej ib txwm zoo.Thaum ob los yog ntau tshaj tus lej zoo ntxiv ua ke, qhov tshwm sim los yog sum yog ib txwm zoo. Lub sumof ib tug zoo thiab ib tug tsis zoo integer yuav ua tau zoo, tsis zoo, los yog xoom
Vim li cas cov nqi zoo thiab tsis zoo nyiam?
Tus nqi tsis zoo xav muab nws cov electrons los ua qhov nruab nrab yog li nws nyiam qhov zoo ntawm nws. Ntawm qhov tod tes, ib tug zoo chargere yuav tsum tau electrons los ua nruab nrab, yog li ntawd nws txav mus rau tus nqi tsis zoo
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
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
