Qhov no feem ntau txhais tau hais tias nyob rau hauv aqueous tov ntawm tus qauv kub thiab siab, qhov concentration ntawm hydronium ions yog sib npaug rau cov concentration ntawm muaj zog acid qhia txog kev daws teeb meem. Ionization ntawm kua qaub thiab bases hauv dej : A muaj zog acid ionizes kiag li nyob rau hauv ib tug aqueous tov los ntawm poob ib proton (H +).
Raws li txoj cai, vim li cas cov kua qaub muaj zog sib cais hauv dej?
Thaum HCl molecules yaj lawv tsis sib haum hauv H+ ions thiab Cl- ions. HCl yog a muaj zog acid vim nws dissociates yuav luag kiag li . Hauv cov ntsiab lus: qhov muaj zog dua kua qaub qhov ntau dawb H+ ions raug tso tawm rau hauv kev daws teeb meem. Qhov ntau dua tus naj npawb ntawm H+, qhov qis dua tus nqi pH rau qhov ntawd kua qaub.
Tsis tas li ntawd, vim li cas cov kua qaub ionize hauv dej? Cov kua qaub thiab bases dissolve nyob rau hauv dej thiab, vim hais tias lawv nce lub concentration ntawm ib qho ntawm cov khoom ntawm dej tus kheej- ionization , xws li protons lossis hydroxide ions, lawv suppress dej kev tsis sib haum xeeb. Rau ib qho twg kua qaub , Ka yog qhov equilibrium tas mus li kua qaub dissociation cov tshuaj tiv thaiv hauv dej.
Ib tug kuj yuav nug, puas muaj zog acids kiag li ionize hauv dej?
Ib kua qaub los yog lub hauv paus lub zog hais txog nws qib ntawm ionization . A muaj zog acid yuav tag nrho ionize hauv dej thaum qaug zog kua qaub yuav tsuas yog ib feem ua ionize . Ib tug muaj zog kua qaub yuav yog ib tug zoo proton pub, yuam kom sib npaug mus rau sab xis. Qhov no tsim ntau hydronium ions thiab conjugate puag.
Vim li cas thiaj muaj zog acids siab ionise?
A muaj zog acid yog ib kua qaub uas yog tag nrho ionized nyob rau hauv ib tug aqueous tov. Hydrogen chloride (HCl) ionizes kiag li rau hauv hydrogen ions thiab chloride ions hauv dej. Tsis muaj kua qaub , zoo li muaj zog acids , ua ionize los ua tus H+ ion thiab conjugate puag. Vim HCl yog ib muaj zog acid , nws conjugate puag (Cl−) yog heev qaug zog.

Lub ntiaj teb yuav hloov li cas yog tias cov nyhuv tsev cog khoom tsis muaj nyob rau hauv tag nrho cov lus nug?
A) Yog tsis muaj cov nyhuv tsev cog khoom, lub ntiaj teb yuav tawg tag nrho nws cov cua sov rau hauv qhov chaw. b) Txhua lub hnub ci hluav taws xob tuaj yeem nqus tau yam tsis muaj lub tsev cog khoom. C) Qhov tshwm sim ntawm tsis muaj cov nyhuv tsev cog khoom yuav yog lub ntiaj teb kub heev uas yeej tsis txias
Yuav ua li cas yog tag nrho cov electromagnetic nthwv dej muaj nyob rau hauv ntau quizlet?
Dab tsi yog tag nrho cov electromagnetic nthwv dej muaj qhov sib xws? Lawv tuaj yeem taug kev ntawm lub teeb nrawm. Lawv muaj tib lub wavelengths. Lawv tsuas taug kev los ntawm qhov teeb meem
Dab tsi lub cev muaj zog ua rau tag nrho cov alkali hlau muaj?
Cov yam ntxwv ntawm Alkali Metals Pom nyob rau hauv kem 1A ntawm lub sijhawm teem sijhawm. Muaj ib tug electron nyob rau hauv lawv txheej txheej ntawm electrons. Yooj yim ionized. Silvery, mos, thiab tsis ntom. Tsawg melting ntsiab lus. Zoo kawg nkaus reactive
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Ntau npaum li cas ntawm cov pej xeem hauv ntiaj teb nyob ntawm cov kab ke roob rau tag nrho lossis qee qhov ntawm lawv cov dej?
Roob yog lub ntiaj teb "dej yees," muab 60-80% ntawm tag nrho cov dej tshiab rau peb ntiaj chaw. Tsawg kawg ib nrab ntawm lub ntiaj teb cov pej xeem nyob ntawm roob ecosystem kev pabcuam kom muaj sia nyob - tsis yog dej xwb, tab sis kuj muaj zaub mov thiab lub zog huv
